0. INTRODUCTION
===============
o This document provides information on various Doom, Ultimate Doom and Doom II
 games, and compares the game-console and handheld versions to the original PC
 editions, and to each other.

o Apple Macintosh ("Mac") and other computer-based editions of the PC Doom
 games exist, however they are identical in most aspects to the PC games, and
 so are generally not addressed in this document.  Other editions of Doom or
 Doom II not addressed here may be included in future updates.

o This document does not address the "Final Doom" games for the PC and the Sony
 PlayStation, or the "Master Levels" games/maps for the PC, PlayStation and
 Microsoft Xbox.  A similar document comparing these games can be accessed at:
 http://classicdoom.com/fdoomcmp.htm

o In the game descriptions included in this document, "Pros" are notable
 features of the indicated game version, some of which may set it above other
 versions covered here; "Cons" are generally features that existed in the
 original PC game(s) but are missing from the indicated version, or may
 otherwise cause a version to be rated below other versions covered here;
 "Miscellaneous" notes cover those features which do not necessarily fall
 under the other categories.

o This document is 79 characters wide, and is best viewed in a monospaced font.

1. DOOM/DOOM II GAMES: GENERAL
==============================
o All Doom/Doom II games in this document feature these basic game elements:

 Monsters     |Weapons        |Ammo                    |Items and Artifacts
 -------------|---------------|------------------------|----------------------
 Baron Of Hell|BFG 9000       |Box of bullets          |Backpack
 Cacodemon    |Chaingun       |Box of rockets          |Berserk Pack
 Demon        |Chain saw      |Box of shotgun shells   |Combat/Mega Armor

              |Shotgun        |Shotgun shells (cluster)|Medikit
              |               |                        |Radiation suit/shield
              |               |                        |Security Armor
              |               |                        |Skull Key
              |               |                        |Soul Sphere
              |               |                        |Spiritual Armor bonus
              |               |                        |Stimpack
 -----------------------------------------------------------------------------
 Notes: These elements exist in all Doom games including Nintendo 64 Doom 64
 (which, unlike other console versions, is not a copy of an original PC game).
 "Monsters" include enemy types found in all Doom, Ultimate Doom, and Doom II
 games.  Doom 64, and every Doom II game (or Episode) will also include these
 monster/enemy types: Arachnotron, Hell Knight, Mancubus, and Pain Elemental.
 In Doom 64, the pink "Demon" monster is referred to as a "Bull Demon".
 Note that not all monsters, items, etc. appear in all games at all difficulty
 levels.  Also, some elements found on a given map during a single-player game
 may be absent from the same map during a multiplayer game, and vice versa.
 In Sega 32X Doom, a BFG 9000 weapon is only available when using cheat codes.
 For more about Doom cheat codes, access: http://classicdoom.com/doomcode.htm

o In all Doom/Doom II games, a player character may walk, turn, run, "jump"
 (run across small gaps), and side-step/strafe.  In almost all Doom games,
 these maneuvers can be done both in first-person mode, and while the Automap
 screen is displayed.

o All Doom/Doom II games can experience speed fluctuations during gameplay.
 In general, overall game speed will drop/rise with an increase/decrease in
 sprites and textures displayed on the screen.

o The following are limitations in all console and handheld Doom/Doom II games:
 Deathmatch games cannot include monsters; No built-in ability to import
 external map levels, customized graphics, or sounds/music; No way to adjust
 graphics resolution for a given screen size; Cannot place numerical markings
 on the Automap.

o Most non-computer Doom/Doom II games exclude some of the maps that exist in
 the original PC games, and/or include maps not found in the PC games.  (Some
 game-console versions also have new hidden exits added to some map levels.)
 Because of this, the exact playing order of map levels can differ from that
 of the comparable PC game.

o In all Doom games, monsters can turn and/or move in any one of at least 8
 lateral directions.  In the Super Nintendo and Sega 32X games, monsters
 often appear to be walking backwards, or "crab-walking" sideways, because
 artwork is supplied only for their forward-facing surfaces.  (No sprites are
 included to give the appearance of turning or facing away from the player.)

o Most console Doom games allow cheats to be invoked with an ordinary game
 controller.  Various cheats may also be loaded into many console/handheld
 Doom games with separately sold devices (such as a Game Genie or Game Shark)
 that plug into the game system.

2. COMPUTER-BASED DOOM/DOOM II GAMES
====================================
o Various IBM-PC 486 computers, and PC-compatible 486 and Pentium computers,
 were used as the test systems for the PC games described in this document
 (version 1.9 of PC Ultimate Doom and version 1.9 of PC Doom II: Hell on Earth
 were tested, as well as various earlier versions of all PC Doom and Doom II
 games).  For testing multiplayer games, these computers were connected to
 similar systems via various network and/or modem connections.

o Pros: In general, more features and options, and greater versatility than all
 game-console or handheld versions of Doom or Doom II.  2 players may play
 simultaneously via modem connection; Up to 4 may play via network connection.
 On a modern PC, gameplay is somewhat faster/smoother than in most console/
 handheld versions.  Ability to use and configure a variety of input devices
 (keyboard, mouse, joystick, gamepad, etc.) for game play.  Doom II-based PC
 games include more monster types than are available in many console/handheld
 Doom or Doom II games.  A game in progress may be saved at any point (to any
 of several save-game slots) and restored later to the same point.  Saved
 games retain copious information (player location, health, weapon, ammo and
 armor status, live/dead status of all monsters on the map level, etc.).
 Supports 9 screen sizes, which also allows the first-person view to be
 expanded to fill the entire screen.  Deathmatch games may include monsters.
 PC Doom 1's entire first Episode is still available as shareware.  Thousands
 of external map levels are available for use with these games.  Built-in
 ability to record or watch single-player/multiplayer gameplay sessions.
 Later PC Doom/Doom II game releases include extensive documentation and
 reference material with the software.  Separate utilities exist which allow
 players to create or edit new map levels, new artwork and/or new sounds for
 existing Doom/Doom II games.  A variety of free third-party Doom engines have
 been released, which add improved graphics, better multiplayer support and
 other features to the commercial PC games.  Wide variety of built-in cheat
 codes.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC
 Doom/Doom II games, including areas on some levels where players may become
 inadvertently trapped, a program bug that creates nearly-intangible monsters,
 a bug that can allow a player character to become stuck partially inside
 solid objects when reloading saved games, and a bug in Doom II where the game
 can crash if a map-30 save-game file is reloaded.

o Miscellaneous: Games by id Software.  Disk or CD format; Also available via
 direct download through www.idsoftware.com.  Decent graphics resolution and
 quality; Very good in some hardware/software configurations.  The commercial
 edition of Doom ("Doom 1") for the PC includes 27 map levels, divided into
 three 9-map Episodes.  A later reissue of the game, titled "The Ultimate
 Doom: Thy Flesh Consumed", includes the original three Episodes and a newer
 fourth Episode which includes 9 more map levels.  Doom II ("Doom 2: Hell on
 Earth") for the PC has 32 map levels built in, and adds new monsters and a
 double-barrelled shotgun not found in Doom 1 or Ultimate Doom.  Occasionally
 when a Pain Elemental monster (in Doom II) dies, the Lost Souls generated by
 its explosion may be flung through nearby walls, where they may become
 trapped (this has little effect on the game, since Lost Souls do not count
 towards a Kills score).  Unlike some console/handheld versions, a player can
 only cycle between fist and chain saw while a Berserk power-up is in effect.

3. SONY PLAYSTATION DOOM
========================
o A Sony PlayStation, model SCPH-1001, equipped with one standard PlayStation
 controller (model SCPH-1080), was used as the test system for the Custom
 PlayStation Edition of Doom described in this document.  For testing
 multiplayer games, the system was connected to an identical system via the
 PlayStation Link cable (model SCPH-1040).

o Pros: Features most of the map levels (or equivalents) from the PC games "The
 Ultimate Doom" and "Doom II" (Doom 2: Hell on Earth).  Large variety of
 monster types (17) compared to many other game-console and handheld versions.
 Link ability (for compatible systems) allows 2-player Deathmatch and Co-Op
 games.  The first-person view and status bar combination fills the entire
 display space on the TV/monitor screen (some other console versions of the
 same era do not support this).  Map level, skill level, health, armor, weapon
 and ammo information is translated to a password code which is given after
 successful completion of each map level (some other console Doom games cannot
 save such information externally).  The last password entered or generated on
 the password screen may be re-entered with a single button press (useful
 when, for example, a player is killed and wishes to restart on the map with a
 non-default status).  Extensive controller customizing is allowed the (Fire
 button can swap functions with Speed button or Activate button, etc.).

o Cons: The 24 maps from Jaguar Doom are incorporated (with minor edits) into
 the 33-map "Ultimate Doom" Episode (most of the maps in Atari Jaguar Doom are
 edited/simplified versions of the original PC Doom maps).  Minor errors
 appear in a few map levels (secret room impossible to access, difficulty in
 picking up an item, etc.).  No crushing ceilings in the "Ultimate Doom" maps.
 From powering up the PlayStation, there is a relatively long wait (over a
 minute) before the player can actually start playing.  Game cannot make use
 of a memory card (sold separately).  Game does not save controller or sound
 configuration settings.  Some monster/enemy types from PC Doom II are missing
 from this version, including the Arch-Vile, "SS Officer", and the "Baphomet"/
 Boss entity.  Occasionally, objects in the foreground are partially overlaid
 by background wall or floor textures.  Weapons are cyclic-access only
 (although weapon choices may be cycled while the game is paused).  The status
 bar can only display the ammo level of the currently selected weapon (in PC
 and some other games, all ammo levels for all weapons can be displayed at all
 times).  All of the built-in cheat codes are rather long and complex (for
 example, an invincibility cheat code is 3 button-presses on the Jaguar, 5 on
 the PC, 10 on the PlayStation).  No "Gamma Correction" feature or equivalent.

o Miscellaneous: Port by id Software and Williams Entertainment, Inc.  CD
 format.  59 map levels, 8 of which are not found in PC Doom/Doom II games.
 Good graphics resolution and quality.  Gameplay speed is adequate, but is
 somewhat slower than a PC Doom/Doom II game played on a modern computer.
 Game information stored in a password code may be inaccurate (health, armor
 and ammo level numbers tend to be rounded).  Features music tracks (and other
 background audio effects) not found in PC Doom games.  Features new colored
 lighting effects.  Health potions and Spiritual Armor bonuses add 2% to a
 player's health or armor (versus 1% in the PC games).  In PC Doom II, the two
 shotgun types are both represented as weapon 3 in the status bar; In PSX
 Doom, the shotgun types are separated into weapons 3 and 4.  No "Nightmare"
 skill level.  Some Doom II monsters (Heavy Weapon Dude, Revenant, etc.)
 appear in the "Ultimate Doom" maps when playing at the highest skill level
 ("Ultra Violence").  Monster and weapon sounds tend to differ from the sounds
 used in the PC games.  In this game, "blurred" objects are translucent and
 faded, but otherwise maintain their normal colors and surface features (in
 the PC games, "blurred" objects, when visible, are a translucent gray, with a
 flat, flowing/scrambled surface).  Another version of the Spectre appears in
 this game: the "Nightmare Spectre", which appears visibly darker, and is
 harder to kill than the normal Spectre.  The Nightmare Spectre is a not a
 1-to-1 replacement for the missing Arch-Vile monster.  Very tall rooms/areas
 from equivalent maps in the PC game(s) are lower in this version.  An "X-ray
 vision" cheat code not found in the PC games is included.  An animated "wall
 of fire" exterior background is used in some map levels.  Some monsters and
 monster projectiles tend to move slower than their PC-game counterparts.
 Graphics "noise" may sometimes be seen along the top or bottom edges of
 walls.  On occasion, the "marine face" in the status bar explodes when the
 player character dies.  On occasion, when a Pain Elemental monster dies, the
 Lost Souls generated by its explosion may be flung through nearby walls,
 where they may become trapped.  Lost Souls that are trapped behind walls may
 still be visible, but may be impossible to kill (this normally has no effect
 on the game, since Lost Souls do not count towards a Kills score).  The voice
 effect that accompanies "victory text" is not heard if Music Volume is turned
 down.  Some monsters on the original PC maps are replaced with different
 monsters on the equivalent maps in this version.  In 2-player games, both
 player characters wear a green uniform.  In Cooperative games, Frags are not
 indicated in the tally screens.  The "WOLFENSTEIN" and "GROSSE" secret map
 levels from PC Doom II do not appear in this game.  The "Commander Keen"
 character from PC Doom II is not included.  The "Lots of Goodies" cheat code
 will not add keys if they are not necessary.

 Notes: Map equivalency is based on general map layouts, not map names.
 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 The PSX "HELL KEEP" map does not match the PC "HELL KEEP" map.  (It does,
 however, match an equivalent map in the Saturn, Jaguar, 3DO and GBA Doom 1
 games.)

4. SEGA SATURN DOOM
===================
o A Sega Saturn unit, model MK-80000A, equipped with one standard Sega Saturn
 Control Pad (model MK-80116), was used as the test system for the NTSC Sega
 Saturn Doom game described in this document.

o Pros: Features most of the map levels (or equivalents) from the PC games "The
 Ultimate Doom" and "Doom II" (Doom 2: Hell on Earth).  Large variety of
 monster types (17) compared to many other game-console and handheld versions.
 The first-person view and status bar combination fills the entire display
 space on the TV/monitor screen (some other console versions of the same era
 do not support this).  Map level, skill level, health, armor, weapon and ammo
 information is translated to a password code which is given after successful
 completion of each map level (some other console Doom games cannot save such
 information externally).  The last password entered or generated on the
 password screen may be re-entered with a single button press (useful when,
 for example, a player is killed and wishes to restart on the map with a
 non-default status).  Extensive controller customizing is allowed (the Fire
 button can swap functions with Speed button or Activate button, etc.).

o Cons: No multiplayer ability (NTSC edition).  Overall game speed is slower/
 choppier in than in the PC games and some other game-console versions.  The
 24 maps from Jaguar Doom are incorporated (with minor edits) into the 33-map
 "Ultimate Doom" Episode (most of the maps in Atari Jaguar Doom are edited/
 simplified versions of the original PC Doom maps).  Minor errors appear in a
 few map levels (secret room impossible to access, difficulty in picking up an
 item, etc.).  No crushing ceilings in the "Ultimate Doom" maps.  Game cannot
 make use of a memory cartridge (sold separately).  This game does not save
 controller or sound/music configuration settings.  "Strafing"/side-stepping
 tends to be somewhat slower here than in many other versions.  Weapons are
 cyclic-access only, and can only be cycled in one direction.  Some monster/
 enemy types from PC Doom II are missing from this version, including the
 Arch-Vile, "SS Officer", and the "Baphomet"/Boss entity.  The status bar can
 only display the ammo level of the currently selected weapon (in PC and some
 other game versions, all ammo levels for all weapons can be displayed at all
 times).  Background objects or surfaces may occasionally overlap foreground
 objects or surfaces.  No "Gamma Correction" feature or equivalent.

o Miscellaneous: Port by Rage Software (NTSC edition).  CD format.  59 map
 levels, 8 of which are not found in PC Doom/Doom II games.  Decent graphics
 resolution and quality.  Sega Saturn Doom is very similar to the earlier
 PlayStation (PSX) Doom game (map levels, monsters, sound effects, music, and
 passwords used are all virtually identical).  Saturn Doom graphics are
 similar to the PSX Doom graphics, but lack some of the enhanced lighting and
 color effects used in PSX Doom.  Game information stored in a password code
 may be inaccurate (health, armor and ammo level numbers tend to be rounded).
 Health potions and Spiritual Armor bonuses add 2% to a player's health or
 armor (versus 1% in the PC games).  In PC Doom II, the two shotgun types are
 both represented as weapon 3 in the status bar; In Saturn Doom, the shotgun
 types are separated into weapons 3 and 4.  No "Nightmare" skill level.  Some
 Doom II monsters (Heavy Weapon Dude, Revenant, etc.) appear in the "Ultimate
 Doom" maps when playing at the highest skill level ("Ultra Violence").
 Monster and weapon sounds tend to differ from the sounds used in the PC
 games.  In this game, "blurred" objects are translucent and faded, but
 otherwise maintain their normal colors and surface features (in the PC games,
 "blurred" objects, when visible, are a translucent gray, with a flat,
 flowing/scrambled surface).  A second version of the Spectre appears in this
 game: the "Nightmare Spectre", which looks like the normal Spectre, but is
 harder to kill.  The Nightmare Spectre is a not a 1-to-1 replacement for the
 missing Arch-Vile monster.  Very tall rooms/areas from equivalent maps in the
 PC game(s) are lower in this version.  Some monsters and monster projectiles
 tend to move slower than their PC-game counterparts.  The player character's
 basic running speed (compared to other moving objects in the environment) is
 somewhat faster here than in other versions.  In general, each weapon's
 "rapid-fire" rate is higher here than in other Doom games.  Graphics "noise"
 may sometimes be seen along the top or bottom edges of walls.  On occasion,
 when a Pain Elemental monster dies, the Lost Souls generated by its explosion
 may be flung through nearby walls, where they may become trapped.  Lost Souls
 trapped behind walls may still be visible, but may be impossible to kill
 (this has little effect on the game, since Lost Souls do not count towards a
 Kills score).  The voice effect that accompanies "victory text" is not heard
 if Music Volume is turned down.  Some monsters on the original PC maps are
 replaced with different monsters on the equivalent maps in this version.
 Player may select stereo (default) or monophonic audio.  Stereo sounds may
 occasionally phase-shift, giving false impressions of sound sources (for
 example, during continuous firing of the player's chaingun, some of the
 reports may seem to originate from a point to the player's left or right).
 Pausing the game does not interrupt music.  "DEMO" will flash on the screen
 while demo games are shown.  3 demo games are shown during Attract mode
 (including demos from 2 "secret" map levels), then the third demo is repeated
 once before cycling back to the first.  In most Doom/Doom II games that end
 victoriously with a "parade" (or "Cast of Characters"), the parade repeats
 until the player resets or restarts the game; In Saturn Doom, the parade runs
 through one time, and then the game returns to the Main Menu screen.  The
 "WOLFENSTEIN" and "GROSSE" secret map levels from PC Doom II do not appear in
 this game.  The "Commander Keen" character from PC Doom II is not included.
 The "Lots of Goodies" cheat code will not add keys if they are not necessary.

 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 The Saturn "HELL KEEP" map does not match the PC "HELL KEEP" map.  (It does,
 however, match an equivalent map in the PSX, Jaguar, 3DO and GBA Doom 1
 games.)

5. NINTENDO 64 DOOM 64
======================
o Note that Doom 64, unlike other console/handheld Doom games, is not a direct
 port or conversion of an existing PC Doom game.  It does, however, share many
 of the same features and functions found in all other Doom and Doom II games.

o A Nintendo 64 Control Deck, model NUS-001, equipped with one standard
 Nintendo 64 Controller (model NUS-005), was used as the test system for the
 Doom 64 game described in this document.

o Pros: Comparatively smooth, high-resolution graphics produced through dynamic
 antialiasing.  The "pixelation" effect (a drop in graphics resolution seen in
 other Doom games as the player character approaches a surface or object) is
 notably reduced here.  Features some new graphics effects (fog/mist, fading
 objects, animated skies, etc.).  First-person view fills the entire space on
 the TV/monitor screen (with or without the "status bar" displayed).  The
 "bar" of the "status bar" is invisible: only the numerals used for health,
 ammo and armor, and the icons used for keys, will actually obstruct any part
 of the first-person view.  The status bar may be switched off, allowing only
 the first-person view to fill the screen.  Map level, skill level, health,
 armor, weapon and ammo information is translated to a password code which is
 given after successful completion of each map level (some other console Doom
 games cannot save such information externally).  On the password screen, the
 last password entered or generated may be re-entered with a single button
 press (useful when, for example, a player is killed and wishes to restart on
 the map with a non-default status).  The game supports a "Controller Pak" (a
 separately-sold memory cartridge device) which allows storage and retrieval
 of up to 16 game passwords.  Built-in screen brightness adjustment option,
 somewhat similar to the "Gamma Correction" feature in the PC Doom games.
 Automap is dual-mode, allowing a player to view the map with a detailed
 textured floor (using an Area's actual floor textures), or view the map as a
 plain (PC-Doom style) untextured Automap.  Extensive controller customizing
 is allowed (the Fire button can swap functions with Speed button or Activate
 button, etc.), including an ability to choose and/or modify any one of 5
 preset configurations.  Player may walk and move in the game with the
 controller's directional-pad buttons, and/or with the controller's built-in
 joystick.  The player character can rotate at varying speeds: turning slowly
 using controller buttons, marginally faster using the joystick, or very fast
 with the joystick if "Controller Stick Sensitivity" is increased through a
 setting under the game's Options Menu.  The game provides a feature for
 "centering" the position of the game screen on the display device, allowing
 horizontal and vertical adjustments.  Game messages (such as "PICKED UP A BOX
 OF SHELLS") may be toggled on or off, as can be done in the PC Doom games.

o Cons: No multiplayer ability.  On some display devices the first-person view
 may seem too dark, and/or the status bar data may be difficult to read, even
 when the game's brightness level is set to maximum.  Occasionally objects in
 the foreground are partially overlaid by background wall or floor textures.
 Weapons are cyclic-access only (but may be cycled in both directions).  Game
 does not save controller, display, or sound configuration settings.  Although
 joystick-based turning speed can be greatly increased through a setting under
 the game's Options Menu, D-pad (or button-based) turning speed cannot.  The
 status bar can only display the ammo level of the currently selected weapon
 (in PC and some other game versions, all ammo levels for all weapons can be
 displayed at all times).  Once in Automap mode, a player must cycle through
 both Automap styles to return to the first-person view (this can be done
 almost instantaneously if desired, but must be done every time the Automap is
 accessed).  At 16 characters long, the passwords are somewhat cumbersome to
 enter, unless they are stored in a separately-sold Controller Pak memory
 cartridge.  The Zombieman and Shotgun Guy enemy types are very similar in
 appearance, and may be indistinguishable during combat.  The delay between a
 player character's death and subsequent resurrection is longer here than in
 other Doom games.

o Miscellaneous: Game by Midway Home Entertainment, Inc. and id Software.
 Cartridge format.  32 map levels, none of which are found in PC Doom/Doom II
 games.  Gameplay speed is adequate, but some aspects of a player character's
 motion (such as running speed) may be marginally slower here than in a PC
 Doom/Doom II game played on a modern computer.  More monster/enemy variety in
 this game than in most Doom 1-based games (several of the Doom 64 monster
 types are based on PC Doom II types).  With some new features and completely
 re-worked graphics, the "look and feel" of this game bears only a distant
 resemblance to all other Doom games.  All enemies have a modified appearance,
 and in some cases are only vaguely similar to their counterparts in other
 Doom or Doom II games.  Virtually all objects and surface textures have been
 changed from their original designs, including weapons, power-ups, walls,
 floors, ceilings, switches and teleporters.  Map levels may have structures
 that simulate crossing paths at different heights (such as a solid "bridge"
 that a player can walk over or under), and similar map features which are not
 found in other Doom games.  Graphics, overall, tend to be darker here than in
 most other versions.  Features new music tracks (and other background audio
 effects) not found in the PC games.  Some features appear in this game that
 appear in no other Doom or Doom II game, including horizontally-sliding
 surfaces, wall-mounted monitors that can be used to view distant parts of the
 map, automated traps that launch projectiles, etc.  Doom 64 features a new
 "Boss" monster (referred to in the game as the "Mother of all Demons") which
 is not found in any other Doom game.  The Spider Mastermind monster found in
 most other Doom games is not included.  Another version of the Imp appears in
 this game: the "Nightmare Imp", which is semi-translucent, darker, and faster
 than the normal Imp, and launches high-velocity fireballs.  Arachnotrons fire
 twin, side-by-side plasma bursts (versus single-stream bursts in all other
 games).  Pain Elemental monsters can release 2 Lost Souls at a time (versus a
 maximum of 1 at a time in all other games).  Lost Souls are semi-translucent
 in this game, and tend to attack more quickly than their counterparts in
 other games.  In Doom 64, Baron-Of-Hell projectiles can injure Hell Knights,
 and vice-versa (in other Doom/Doom II games, both projectiles are harmless to
 both monsters).  The "Demon" monster (a pink, muscular, hunched-over, biting
 monster), is referred to as a "Bull Demon" in the manual included with the
 game.  A Spectre Demon is opaque until it discovers a player character,
 whereupon it becomes translucent.  If a translucent Spectre Demon is killed,
 its body becomes opaque.  A new laser-type weapon appears in this game, and
 uses the same "cell" ammunition as a plasma rifle or BFG 9000.  Doom 64
 includes a unique type of power-up (referred to in this document as a "Demon
 Artifact") which acts both as an enhancement for the new laser weapon, and as
 a special key/activator for use within the game's final map level.  Demon
 Artifacts have an appearance somewhat similar to the demon/pentagram graphic
 that is used both in the game's tally screens and on the cover of the game's
 manual.  When a Demon Artifact is picked up, an icon representing that
 particular Artifact appears at the lower-right corner of the Automap screen.
 A double-barrelled "Super Shotgun" (similar to the weapon found in Doom II
 games) appears in this game.  The double-barrelled shotgun and the rocket
 launcher both have a "kick" when firing, giving a slight backwards push
 against the player character.  In this game, the plasma rifle tends to make a
 continuous buzzing noise whenever it is selected as the current weapon.  In
 this game, the chain saw has a pair of blades, side by side (versus a single
 blade in all other Doom games).  In all other Doom games, only players and
 monsters may be teleported from place to place; In Doom 64, other objects
 (power-ups, weapons, and structures) may also be moved from place to place,
 or fade in and out of existence.  Occasionally monsters will spontaneously
 "fade in" to a location on the current map (an effect which is similar to
 teleportation).  Game information stored in a password code may be inaccurate
 (health, armor and ammo level numbers tend to be rounded).  Monster and
 weapon sounds tend to differ from the sounds used in the PC games (in fact
 most sound effects are identical to those used in the PlayStation/PSX Doom
 games, released prior to Doom 64).  The sound effect used in PSX Doom for an
 item re-spawning during a Deathmatch game is used in this game to indicate
 that a monster or item/object is "fading into" (or "spawning into") a nearby
 location.  In this game, "blurred" objects are translucent and faded, but
 otherwise maintain their normal colors and surface features (in the PC games,
 "blurred" objects, when visible, are a translucent gray, with a flat,
 flowing/scrambled surface).  Explosive barrels are not mentioned in the game
 manual, but do appear in this game, as they do in all other Doom games.  The
 "marine face", seen in the status bar of all other Doom/Doom II games, is not
 in the status bar in this game.  "Secret areas" are usually announced (via
 on-screen messages) as a player character enters them.  While walking/running
 in Automap mode, the player icon does not turn to change direction; instead,
 the Automap rotates around the icon, which is always facing north.  In this
 game, the "radiation shield" power-up appears as a green "biohazard" symbol,
 instead of as the white, full-body "radiation suit" seen in all other Doom
 games.  The physical location of an item on a given map can vary with the
 skill level that the map is played on (for example, the blue keycard in the
 STAGING AREA map is in an open area when the game is played on skill 1, but
 is located in a small, closed room on skill 4).  Doom 64 uses skill level
 names unique among console Doom games: "BE GENTLE!", "BRING IT ON!", "I OWN
 DOOM!", and "WATCH ME DIE!".  Some surfaces with 1-way transparency are used
 in this game (a feature missing from most other non-computer versions).  In
 Doom 64, entering a valid map 1 password, or using a special locked exit on
 map 32, will reveal a hidden "Features Menu", which allows access to various
 cheat functions.  On occasion, the first-person display will shake as an
 indication of a major change in the current map level (changes in the map's
 topography, structures, etc.).  When firing a weapon, the first-person view
 can jump or vibrate with the weapon's recoil.  Every 30 seconds of idle time
 after a player character dies, the game will display one of 12 "taunts" (such
 as "HAHAHAHA!" or "HAVE YOU HAD ENOUGH?").  Both shotgun types are reloaded
 without the relatively elaborate reloading animation seen in all other Doom/
 Doom II games (however the weapon reloading times remain comparable to those
 of the other games).  In most Doom and Doom II games the plasma rifle is
 swung up and to the side for a moment at the end of a firing sequence; in
 this game the weapon always faces forward.

 or Doom II game.

6. ATARI JAGUAR DOOM
====================
o An Atari Jaguar 64-Bit Interactive Multimedia System, equipped with one
 standard Jaguar controller, was used as the test system for the Atari Jaguar
 Doom game described in this document.  For testing multiplayer games, the
 system was hooked to an identical system via the Jaglink Interface cable.
 Multiplayer games were then tested with identical systems hooked together
 via Catbox interface devices (sold separately by ICD, Inc.).

o Pros: 2-player ability (although multiplayer function may be unstable).  The
 first-person view and status bar combination fills the entire display space
 on the TV/monitor screen (some other console versions of the same era do not
 support this).  Some controller customizing allowed (the Fire button can swap
 functions with Speed button or Activate button, etc.).  Memory built into the
 game cartridge will automatically store controller configuration settings,
 the sound volume setting, the current skill level setting, and also stores
 the map level numbers of all Areas that were successfully conquered (except
 Area 24).  When first starting up the game, a player may choose to start play
 on any of 23 map levels previously conquered (this is a quick process, as
 there are no passwords to keep or re-enter), and may choose a different skill
 level to play it at.  During a game in progress, weapons are direct-access.
 The built-in cheat codes may be entered quickly and easily (for example, an
 invincibility cheat code is 3 button-presses on the Jaguar, 5 on the PC, 10
 on the PlayStation).  The Jaguar Doom game comes with a plastic overlay which
 fits into the top of the game controller, providing labels and weapon icons
 for the buttons on the controller's keypad.

o Cons: Most of the maps in this game are edited/simplified versions of the
 equivalent PC Doom 1 maps.  Games in progress cannot be saved (but a player
 may start a new game on any of 23 map levels previously conquered).  As
 stated in the game manual, occasional "Network Errors" can occur during
 Deathmatch and Cooperative games, causing a game in progress to suddenly
 start over again on the current map.  Only 7 monster types in the game (tying
 with the Sega 32X and GBA Doom 1 games for least variety).  No Spectre Demon.
 No Cyberdemon or Spider Mastermind monsters.  No Blur Artifacts.  No
 light-amplification visors.  No crushing ceilings.  No music during gameplay.
 Somewhat lower graphics resolution or quality than some other large-screen
 console Doom versions.  The status bar can only display the ammo level of the
 currently selected weapon (in PC and other game versions, all ammo levels for
 all weapons can be displayed at all times).

o Miscellaneous: Port by id Software.  Cartridge format.  24 map levels, 2 of
 which are not found in PC Doom games.  Adequate graphics resolution and
 quality.  Gameplay speed is adequate, but can be somewhat slower than a PC
 Doom game played on a modern computer.  This game's mapset, in whole or in
 part, also appears in the PlayStation, Saturn, 3DO, Sega 32X and GBA Doom 1
 games or Episodes.  Rocket and barrel explosions can penetrate solid walls
 and doors (allowing a player to kill some enemies without ever directly
 encountering them).  Health potions and Spiritual Armor bonuses add 2% to a
 player's health or armor (versus 1% in the PC games).  Picking up an
 Invulnerability Artifact tints the screen bluish-pink, as opposed to the
 white-out effect seen in many other versions.  In 2-player games, both player
 characters wear a green uniform.  In Deathmatch games, the Frag counts for
 both players are displayed in each player's status bar.  Corrosive floors
 (slime, etc.) will decrease a player's health quickly (faster in this version
 of Doom than in most other versions running at a comparable skill level).
 When the "Happy Ammo" cheat code is used, the player attains an ammo level of
 500 rounds for every weapon (versus a specific individual ammo level for each
 weapon in the PC games).  Game manual is written in English, French, German.
 Game manual states that cartridge memory will not accept more than 100,000
 changes to stored information (however this would still allow, for example,
 50 changes a day for more than 5 years).

 -----------------------------------------------------------------------------
 Notes: Map equivalency is based on general map layouts, not map names.
 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 The Jaguar "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No
 Jaguar equivalent exists for the PC "DIS" map.
 The Jaguar "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map.
 (It does, however, match the "TOWER OF BABEL" map in the 3DO and GBA Doom 1
 games, and the "HELL GATE" map in the PSX and Saturn games.)
 The Jaguar "HELL KEEP" map does not match the PC "HELL KEEP" map.  (It does,
 however, match an equivalent map in the PSX, Saturn, 3DO and GBA Doom 1
 games.)

7. 3DO (PANASONIC AND OTHERS) DOOM
==================================
o A Panasonic REAL 3DO Interactive Multiplayer, model FZ-1, equipped with one
 standard Panasonic 3DO controller (model FZ-JP1X), was used as the test
 system for the 3DO Doom game described in this document.

o Pros: Some controller customizing allowed (the Fire button can swap functions
 with Speed button or Activate button, etc.).  Ability to choose between 4
 window sizes (or 6, when using a cheat code) for the first-person view.  3DO
 system memory automatically stores controller configuration settings, the
 sound volume setting, the current skill level setting, the selected window
 size for the first-person view, and also stores the map level numbers of all
 Areas that were successfully conquered (except Area 24).  When first starting
 up the game, a player may choose to start play on any of 23 map levels
 previously conquered (this is a quick process, as there are no passwords to
 keep or re-enter), and may choose a different skill level to play it at.

o Cons: Games in progress cannot be saved (but a player may start a new game on
 any of 23 map levels previously conquered).  No multiplayer ability.  Overall
 game animation speed can be choppy, with frequent micro-pauses to access the
 CD, and animation noticeably slows down and speeds up with variances in the
 number of on-screen textures and sprites.  This game uses the Jaguar Doom
 mapset (most of the maps in Atari Jaguar Doom are edited/simplified versions
 of the original PC Doom maps), and includes no other maps.  No Cyberdemon or
 Spider Mastermind monsters.  No light-amplification visors.  No crushing
 ceilings.  Weapons are cyclic-access only.  First-person view does not fill
 the entire space above the status bar.  Game does not utilize all available
 display space on the TV/monitor screen.  The status bar can only display the
 ammo level of the currently selected weapon (in PC and some other versions,
 all ammo levels for all weapons can be displayed at all times).

o Miscellaneous: Port by Logicware and Art Data Interactive, Inc.  CD format.
 24 map levels, 2 of which are not found in PC Doom games.  Adequate graphics
 resolution and quality.  Gameplay speed, overall, is below the average speed
 of most other Doom games.  Features many of the music tracks from PC Doom,
 re-mastered with new and more distinctive instrumentation.  A built-in cheat
 code allows the first-person view window to be expanded two more times beyond
 the default maximum size (however, larger windows further slow down the
 game).  The game box for 3DO Doom advertises "full screen display", and the
 first-person view is indeed maximized within a window; but the window itself
 (when expanded to any size) is always bordered by static artwork.  Rocket and
 barrel explosions can penetrate solid walls and doors (allowing a player to
 kill some monsters without ever directly encountering them).  Health potions
 and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1%
 in the PC games).  In this game, "blurred" objects are a translucent gray,
 with a plain, flat surface (in the PC games, "blurred" objects, when visible,
 are a translucent gray, with a flat, flowing/scrambled surface).  If the "Map
 All Things" cheat code is used, monster orientations are not indicated, as
 they are in all other game versions that support this cheat code; all object
 indicators point in the same direction.  The "marine face" in the status bar
 always explodes when the player character dies.  Music from the first map
 level accompanies the tally screens.  No "Attract mode"; no demo games.  When
 the "Happy Ammo" cheat code is used, the player attains an ammo level of 500
 rounds for every weapon (versus a specific individual ammo level for each
 weapon in the PC games).

 Notes: Map equivalency is based on general map layouts, not map names.
 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 The 3DO "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No 3DO
 equivalent exists for the PC "DIS" map.
 The 3DO "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map.  (It
 does, however, match the "TOWER OF BABEL" map in the Jaguar and GBA Doom 1
 games, and the "HELL GATE" map in the PSX and Saturn games.)
 The 3DO "HELL KEEP" map does not match the PC "HELL KEEP" map.  (It does,
 however, match an equivalent map in the PSX, Saturn, Jaguar and GBA Doom 1
 games.)

8. SUPER NINTENDO DOOM
======================
o A Super NES Control Deck, model SNS-001, equipped with one standard Super NES
 controller (model SNS-005), was used as the test system for the SNES Doom
 game described in this document.  For testing multiplayer games, the system
 was connected to various similar systems via the X Band network, using a
 Catapult X Band modem device (model 00100).

o Pros: The basic map layouts tend to match the equivalent PC-Doom 1 maps with
 above-average accuracy (higher accuracy, overall, than is found in most other
 early console versions).  Simplified 2-player online Deathmatch ability via
 an X Band Network connection.  SNES Doom includes both the Spider Mastermind
 and Cyberdemon monsters from the original PC games (one or both of these are
 missing from GBA Doom 1 and some large-format console versions).  The Automap
 is actively updated at all times, whether displayed or not (in most other
 Doom/Doom II games, the Automap will not update while displayed).  A player
 character with 200% health will not automatically pick up a Soul Sphere on
 contact (in most other Doom and Doom II games, a Soul Sphere is always picked
 up on contact).  Weapon choices can be cycled while the game is paused.

o Cons: Games in progress cannot be saved.  Comparatively low-resolution
 graphics (most noticeable with distant objects); lowest overall resolution of
 all large-screen Doom games.  Cannot play Episodes 2 or 3 using low skill
 levels.  For multiplayer games, a separately-sold "X Band" modem device, and
 a subscription to the X Band Network, is/was required for each player's game
 system.  Cooperative games are not supported.  Deathmatch games are scaled
 down in this version (no sound effects, items do not re-spawn, an enemy
 player character simply disappears from the Area when killed, exiting a map
 level displays the main menu, where both players must select which map to
 restart the game on, and weapons, ammo, etc., cannot be carried between map
 levels).  Most vertical surfaces tend to be somewhat "sticky", occasionally
 slowing or halting the player character on contact.  Shotguns or ammo clips
 dropped by killed enemies do not appear on the floor/ground.  A player may
 still pick up weapons after ammo levels are at maximum (for example, a player
 may pick up multiple shotguns, even after reaching the maximum carry limit of
 100 shells).  Newly acquired weapons or ammo items contain a standard amount
 of ammunition at all skill levels (in the PC games, the standard amount of
 ammo for each item is doubled when playing at the lowest or highest skill
 levels).  No controller customizing allowed.  Weapons are cyclic-access only
 (although weapons may be cycled while the game is paused), and weapon choices
 can only cycle in one direction.  No real textures for ceilings or floors
 (including corrosives and teleporters).  Monsters can only display a front
 side.  No Spectre Demon.  Cannot save game configuration settings.  Game does
 not utilize all available display space on the TV/monitor screen.  Sounds
 from events at medium or long ranges may be truncated, or may not be played.
 Although monsters can hurt each other, they cannot deliberately fight each
 other.  No screen-flash warning as an Invulnerability Artifact or radiation
 suit begins to wear out.  When the player character is attacked, the "marine
 face" in the status bar does not indicate direction of attack (as it does in
 other Doom games).  Unlike other versions, pivoting and strafing functions
 are mutually exclusive.  The status bar can only display the ammo level of
 the currently selected weapon (in PC and some other game versions, all ammo
 levels for all weapons can be displayed at all times).

o Miscellaneous: Port by Sculptured Software, Inc.  Cartridge format.  22 map
 levels, all of which are found in PC Doom 1.  Gameplay speed is adequate, but
 can be slower than a PC Doom game played on a modern computer.  No "Attract
 mode"; no demo games.  A bug in the game can allow the player to instantly
 acquire additional weapons once a chain saw has been picked up.  In most Doom
 versions, a killed player restarts a map level with 100% health, 0% armor, a
 pistol and 50 bullets; In SNES Doom, a killed player restarts with 100%
 health, and whatever armor, weapons and ammo that the player originally
 brought into the level.  While walking/running in Automap mode, the player
 icon does not turn to change direction; instead, the Automap rotates around
 the icon, which is always facing north (this is also how Automap "scrolling"
 is handled).  Some monsters are easier to kill than their counterparts in
 other versions of the game.  When cycling through weapons, the chain saw
 weapon slot is located between the shotgun and chaingun (in PC Doom the fist
 and chain saw share slot 1).  Unlike other Doom games, Blur Artifacts in SNES
 Doom can render the player undetectable to "waiting" monsters at medium or
 long range; A monster that detects a player at short range can even return to
 "wait" mode if the player moves away.  In this game, "blurred" objects are
 translucent and faded, but otherwise maintain their normal colors and surface
 features (in the PC games, "blurred" objects, when visible, are a translucent
 gray, with a flat, flowing/scrambled surface).  Hitting the Activate/Use
 button can still trigger the "grunt" sound effect, even when the player
 character is nowhere near a wall, switch, or door.  Compared to other Doom
 games, many sound effects in SNES Doom are mismatched with their events, or
 are used for multiple events (for example, a monster's "alert sound" can also
 be used for it's "growl" sound while patrolling).  Some action sequences
 (such as monster deaths, explosions, etc.) use fewer frames of animation than
 the equivalent sequences in other Doom games.  No exploding-monster effect
 (usually seen in PC Doom games when, for example, an Imp or Former Human is
 hit by a rocket).  Teleportation is instantaneous, without the motion-damping
 effect seen in other versions.  No "green spark" effect when a player or
 monster goes through a teleporter.  Impacts of bullets or shotgun pellets on
 walls are not visible.  No panels or switches are activated by projectile
 impacts, as they are in other versions.  An Artifact or power-up can be
 picked up when the player walks over it, but can also be picked up if the
 player is jumping (running) through the airspace above it.  A weapon icon
 appears in the player's status bar to show which weapon is currently held.
 Monster projectiles may affect monsters in ways contrary to what is seen in
 other Doom or Doom II games (a Cacodemon's projectiles can injure other
 Cacodemons, a Cyberdemon can be damaged by its own rockets, etc.).  Unlike
 other Doom games, a Cyberdemon in SNES Doom can use a melee/scratch attack at
 close range (although the normal rocket-firing animation is displayed).  The
 Cyberdemon tends to fire 2 rockets in a row, versus 3 in a row in all other
 versions.  Cyberdemon rockets appear to fly backwards.  A player's chaingun
 fires fewer bullets than what is indicated by the firing sound.  In SNES Doom
 a minimal burst of chaingun fire is typically 1 bullet (with 2 reports),
 versus 2 bullets in most other Doom games.  The plasma rifle fires its
 projectiles at a lower rate than in most other Doom games.  A BFG 9000 will
 use up to 40 energy cells per shot, but can be fired when less than 40 cells
 remain (most Doom/Doom II games always require a minimum of 40 cells).  Some
 projectiles move at faster speeds than in other Doom games.  In most other
 Doom games an elevator/lift will automatically reverse if a player/monster
 prevents it from rising to its highest position; In the SNES game, a blocked
 elevator will simply halt in place, and only move again when the obstacle is
 removed.  Crushing ceilings may not cycle upwards while a player/monster is
 being crushed (unlike certain crushing ceiling types in PC Doom/Doom II).
 Some secret doors/panels are better camouflaged in this game than in PC Doom.
 Players and monsters do not move laterally as a result of impacts or nearby
 explosions, as they do in other Doom games.  Phobos/Deimos/Hell landscapes
 are used as the background for the tally screens between map levels, showing
 the player's progress through the various stages of each Episode (this art is
 omitted from some other non-computer Doom versions).  After a player finishes
 Episode 2, an Episode-3 game begins automatically.  Maps in Episode 3 use the
 same sky/background used in Episode 2 (PC Doom uses a "Hell" sky/background
 for Episode-3 maps).  No scrolling/sliding textures, as are found in other
 Doom games.  No built-in volume controls (but music and sound effects can be
 switched on/off separately).  Most of the original PC Doom story text appears
 in this game.  Both armor-vest types are referred to as "MEGAARMOR" (in other
 games this term is used only for the blue 200%-armor vest).  No built-in
 cheat codes.

 Notes: The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to
 as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 The "E#M#" designators used here for SNES Doom maps are for reference only,
 and are not displayed in the actual game.

9. SEGA GENESIS 32X DOOM
========================
o A Sega Genesis System Console, model 1601, equipped with one standard Sega
 Genesis "6-button" controller (model MK-1653), and one Sega Genesis 32X
 module (model MK-84000A), was used as the test system for the Sega 32X Doom
 game described in this document.

o Pros: Player can always start a game on any of 15 map levels.  The Automap is
 actively updated at all times, whether displayed or not (in most other Doom/
 Doom II games, the Automap will not update while displayed).  Some controller
 customizing allowed (the Fire button can swap functions with Speed button or
 Activate button, etc.).  With a "6-button" controller attached, weapons can
 be accessed directly, or weapon choices can be cycled in both directions.

o Cons: Requires both a Sega Genesis system and the "32X" expansion module.
 This version has the least map levels of all Doom games, and most of the maps
 are edited/simplified versions of the original PC Doom 1 maps.  Games in
 progress cannot be saved (but a player may always start a new game on any of
 15 maps).  No multiplayer ability.  No BFG 9000 weapon available without
 using a cheat code.  Monsters can only display a front side (despite the fact
 that screen shots on the game box and the 32X module box show side views of
 monsters).  Only 7 monster types in the game (tying with the Jaguar and GBA
 Doom 1 games for least variety).  No Spectre Demon.  No Cyberdemon or Spider
 Mastermind monsters.  No Blur Artifacts.  No light-amplification visors.  No
 crushing ceilings.  With a standard Sega "3-button" controller, weapons are
 cyclic-access only, and weapon choices can be cycled in only one direction.
 Cannot save game configuration settings.  First-person view does not fill the
 entire space above the status bar, and game does not utilize all available
 display space on the TV/monitor screen.  Although monsters can hurt each
 other, they cannot deliberately fight each other.  Some rooms on some maps
 are inaccessible.  The few built-in cheat codes can be difficult to implement
 (the code button combinations may have to be pressed several times before a
 code will take effect).  The use of cheat codes can prevent access to some
 maps, and also prevents the game's full ending sequence from being shown.
 The status bar can only display the ammo level of the currently selected
 weapon (in PC and some other game versions, all ammo levels for all weapons
 can be displayed at all times).  Infrequent, brief flashes of graphics
 "noise" may sometimes appear across the first-person view or Automap screen.

o Miscellaneous: Port by id Software.  Cartridge format.  17 map levels, all of
 which are found in PC Doom games.  Decent graphics resolution and quality.
 Gameplay speed is adequate, but can be somewhat slower than a PC Doom game
 played on a modern computer.  Maps 16 and 17 can only be accessed if the game
 was started on map 1, and if cheat codes were not used during the game.  In
 order to see the game's entire ending sequence, a player must start on map
 level 1 and play the game all the way through without using cheat codes (a
 game won any other way will result in the credits being shown, and then the
 game simply halts with a plain textured screen and a "DOS prompt").  Contrary
 to what is stated in the game manual, a player cannot enter map 1 from map
 15; map-level sequence does not "wrap around".  Rocket and barrel explosions
 can penetrate solid walls and doors (allowing a player to kill some monsters
 without ever directly encountering them).  Health potions and Spiritual Armor
 bonuses add 2% to a player's health or armor (versus 1% in the PC games).
 Picking up an Invulnerability Artifact causes a drop in graphics chroma, as
 opposed to the white-out effect seen in many other versions.  Picking up a
 Berserk Pack causes a relatively bright, sustained flash of red, which may be
 mistaken for the effect seen when the player character takes sudden, heavy
 damage.  The shotgun-loading sound is played (sometimes at very low volume)
 for a teleportation event, instead of the teleport sound heard in most other
 versions.  Map level names are not used, only map numbers.  Map numbers are
 only indicated in the tally screens, not while playing a map level.  In the
 Automap, the player icon (an arrow) looks like the one used in the PC games,
 as opposed to the green triangle used in most other versions.  There is an
 option in Automap mode to turn on a grid which overlays the map, and can be
 used as a reference for scale (a feature otherwise found only in the PC
 games).  Rockets fired by the player appear to fly backwards (the nose of the
 rocket faces the player as the rocket moves away).  All monsters, items and
 Artifacts located in very dark areas remain well lit at all times.  Not all
 teleporters function (but all important ones do).  Because graphics are only
 provided to show the front side of objects, some monsters in "wait" mode may
 seem blind when a player approaches them from behind (a monster will always
 appear to look at a player even when it is not actually facing toward the
 player).  When the "Happy Ammo" cheat code is used, the player attains an
 ammo level of 500 rounds for every weapon (versus a specific individual ammo
 level for each weapon in the PC games).

 Notes: The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to
 as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 Map level names are not used in Sega 32X Doom.

10. NINTENDO GAME BOY ADVANCE DOOM
==================================
o A Nintendo Game Boy Advance, model AGB-001, and a Nintendo Game Boy Advance
 SP, model AGS-001, were used as test systems for the GBA Doom game described
 in this document.  For testing multiplayer games, these system were connected
 to identical systems via one or more Nintendo Game Boy Advance Game Link
 cables (model AGB-005).

o Pros: Multiplayer link ability, allowing 2 players in Cooperative games, and
 2 to 4 players in Deathmatch games.  Includes 8 Deathmatch-only bonus maps
 not found in other commercial Doom games.  Some flaws have been corrected in
 some maps which were copied from earlier console Doom games.  A game in
 progress may be saved to any of 4 save-game slots in the Doom Game Pak, and
 save-game data includes controller, lighting and audio settings.  Supports 2
 lighting-style choices, "Dynamic" (normal), and "Static" (low light levels
 are increased, and lights that normally flash are always on).  Has 6-level
 "Brightness" adjustment option (somewhat similar to the "Gamma Correction"
 feature in the PC Doom games), which controls the maximum brightness of both
 Dynamic and Static lighting modes.  Includes an "Autorun" option (player
 always runs).  In the status bar, current ammo levels and ammo limits are
 always displayed for all weapons (in most other console Doom games, only the
 currently selected weapon can have an ammo level displayed).  Some controller
 customizing allowed (any of 6 preset button configurations may be selected).

o Cons: The original Game Boy Advance does not have any built-in lighting for
 its screen, which means that GBA Doom can be difficult to view unless the
 right amount of external light is hitting the screen at the right angle at
 all times (a later model of the GBA, the GBA SP, does have built-in screen
 lighting).  Saved games may occasionally become corrupted, and fail to reload
 correctly.  Cooperative games have a 2-player limit, even when 3 or more GBAs
 are linked.  This game uses a slightly modified version of the Jaguar Doom
 mapset (most of the maps in Atari Jaguar Doom are edited/simplified versions
 of the original PC Doom maps), and includes no other single-player maps.  The
 player character can potentially become trapped behind a wall or barrier on
 certain maps.  Only 7 monster types in the game (tying with the Jaguar and
 Sega 32X games for least variety).  No Spectre Demon.  No Cyberdemon or
 Spider Mastermind monsters.  No Blur Artifacts.  No light-amplification
 visors.  No crushing ceilings.  Weapons are cyclic-access only.  In some of
 the preset button configurations weapon-swapping can be awkward, and weapon
 changes can occur unintentionally when performing certain maneuvers.  Some
 rooms in some map levels are inaccessible.  The sound effect used to indicate
 a player taking damage is also mistakenly used whenever a player lands unhurt
 after falling a short distance.  Frag counts for players in Deathmatch games
 are only displayed in the Automap view.  No tally screen is displayed, and no
 opportunity to save the game is given, when a player goes through the exit to
 the "MILITARY BASE" map level.

o Miscellaneous: Port by David A. Palmer Productions.  Cartridge format.  32
 map levels, 10 of which are not found in PC Doom games.  Decent graphics
 resolution and quality for the GBA screen.  Gameplay speed is adequate, but
 will be somewhat slower than a PC Doom game played on a modern computer.  The
 game's overall speed can be affected by the built-in lighting options, where
 Dynamic Lighting may lower the framerate, and Static Lighting may raise it.
 No "Attract mode"; no demo games.  No "Ultra-Violence" skill setting; the
 highest skill is "Nightmare".  Player can select the fist weapon at any time,
 whether or not a chain saw or Berserk Pack has been acquired.  When monsters
 or players are killed, their corpses disappear after a brief delay.  Monster
 and player blood is green instead of red.  All monsters, items and Artifacts
 located in very dark areas remain well lit at all times.  Sounds produced by
 distant events may be played at an undiminished volume, and/or may penetrate
 walls or areas that are "soundproof" in other Doom games.  When a pink Demon
 is killed, it makes the same sound as a dying Imp (in most other Doom games,
 Imps and Demons will make separate sounds).  No exploding-monster effect
 (usually seen in PC Doom games when, for example, an Imp or Former Human is
 hit by a rocket).  Rocket and barrel explosions can penetrate solid walls and
 doors (allowing a player to kill some enemies without directly encountering
 them).  Teleportation is almost instantaneous, without the motion-damping
 effect seen in most other versions.  In a reversal of the Automap colors used
 in most other Doom games, GBA Doom's Automap displays "viewed" surfaces as
 gray lines, while "unseen" surfaces (added to the Automap when a Computer
 Area Map item is acquired) are displayed in red.  The Automap screen allows 5
 preset zoom levels.  Health potions and Spiritual Armor bonuses add 2% to a
 player's health or armor (versus 1% in the PC games).  Picking up an
 Invulnerability Artifact tints the screen blue, as opposed to the white-out
 effect seen in many other Doom versions.  In this game, muzzle flashes from
 player weapons do not brighten nearby surfaces, as they do in other Doom
 games.  Unlike most other Doom games, Lost Souls are calculated in the Kills
 score displayed in the tally screens.  The tally screen shows both the time
 spent on the map, and the map's Par Time.  Phobos/Deimos/Hell landscapes are
 used as the background for the tally screens between map levels, showing the
 player's progress through the various stages of each Episode (this art is
 omitted from some other non-computer Doom versions).  The "YOU ARE HERE"
 indicators in the tally/landscape screens do not always point to the correct
 locations.  When the "Happy Ammo" cheat code is used, the player attains an
 ammo level of 500 rounds for every weapon (versus a specific individual ammo
 level for each weapon in the PC games).  In this game the player's fist makes
 an impact noise when striking a wall or other inanimate object (in most other
 versions, fist impacts against inanimate objects are silent).

 Notes: Map equivalency is based on general map layouts, not map names.
 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
 The GBA "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No GBA
 equivalent exists for the PC "DIS" map.
 The GBA "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map.  (It
 does, however, match the "TOWER OF BABEL" map in the Jaguar and 3DO games,
 and the "HELL GATE" map in the PSX and Saturn games.)
 The GBA "HELL'S KEEP" map does not match the PC "HELL KEEP" map.  (It does,
 however, match an equivalent map in the PSX, Saturn, Jaguar and 3DO games.)
 GBA Doom maps 25 through 32 are only accessible in Deathmatch games.

11. NINTENDO GAME BOY ADVANCE DOOM II
=====================================
o A Nintendo Game Boy Advance, model AGB-001, and a Nintendo Game Boy Advance
 SP, model AGS-001, were used as the test systems for the GBA Doom II game
 described in this document.  For testing multiplayer games, these system were
 connected to identical systems via one or more Nintendo Game Boy Advance Game
 Link cables (model AGB-005).

o Pros: This game has more maps and monster types than the "DOOM II" Episodes
 of PlayStation Doom or Saturn Doom.  Multiplayer link ability, allowing 2
 players in Cooperative games, and 2 to 4 players in Deathmatch games.  Games
 in progress may be saved to any of 4 save-game slots in the Doom II Game Pak,
 and game data includes controller, lighting and audio settings.  Includes a
 6-level "Gamma" adjustment option to control the overall brightness of the
 game screen.  Controller customizing includes 4 preset button configurations,
 a 5-level "Sensitivity" adjustment option to control the player character's
 pivoting speed, and an "Always Run" option (player always runs).  In the
 status bar, current ammo levels and ammo limits are always displayed for all
 weapons (in most console Doom games, only the currently selected weapon can
 have an ammo level displayed).  The "Happy Ammo" cheat code provides a
 backpack (in most other Doom games, a backpack is not provided, or a player's
 existing backpack is removed).

o Cons: The original Game Boy Advance does not have any built-in lighting for
 its screen, which means that GBA Doom II can be difficult to view unless the
 right amount of external light is hitting the screen at the right angle at
 all times (a later model of the GBA, the GBA SP, does have built-in screen
 lighting).  On rare occasions the game may freeze, and the Game Boy Advance
 must be powered down and restarted.  Cooperative games have a 2-player limit,
 even when 3 or more GBAs are linked.  Occasionally a player weapon fired at a
 close target will auto-aim towards the ceiling/sky or floor/ground.  In some
 of the preset button configurations, weapon-swapping can be awkward, and
 weapon changes may occur unintentionally when performing certain maneuvers.
 Weapons are cyclic-access only.  The auto-aim ability of monsters can remain
 unaffected when the player picks up a Blur Artifact.  Damage to a player's
 armor may not always be accurately represented in the status bar display.
 The scoring system for "Kills" is inaccurate under certain conditions (for
 example, unlike the PC games GBA Doom II counts Lost Souls as score-affecting
 enemies, yet does not actually give credit to the player for killing them).
 Frag counts for players in Deathmatch games are only displayed in the Automap
 view.  When the player character is attacked, the "marine face" in the status
 bar does not indicate direction of attack (as it does in other Doom games).
 Unlike the PC games, a player's running speed is slower in reverse than when
 moving forward.

o Miscellaneous: Port by Torus Games.  Cartridge format.  34 map levels, all of
 which (in whole or in part) are found in PC Doom II: Hell on Earth.  Decent
 graphics resolution and quality for the GBA screen.  Overall gameplay speed
 is adequate, but is somewhat slower than a PC Doom II game played on a modern
 computer.  No "Attract mode"; no demo games.  No "Ultra-Violence" skill
 setting; the highest skill is "Nightmare!".  GBA Doom II maps reflect some
 features found in maps from older versions of PC Doom II (currently the
 latest version of PC Doom II is v1.9).  In this game some maps have minor
 alterations, such as elevators replacing stairs, and strategically placed
 walls/barriers, or deleted windows, in order to reduce the maximum number of
 objects that need to be drawn at any given time.  Some maps in this game have
 major alterations, such as deleted buildings; however in general there are
 fewer large omissions than in many other console/handheld Doom games.  The PC
 Doom II maps INDUSTRIAL ZONE and THE CHASM are each split into 2 "half" maps
 in this game.  When computing collision detection in this game, most of the
 non-structural objects have a comparatively narrow diameter, which can allow
 some objects (such as players and/or monsters) to move very close together,
 or to push past one another, where they could not in PC Doom II.  Unlike most
 other Doom games, the monsters in this game cannot open doors.  Monsters and
 players may occasionally cross above/below one another (a player can even
 stand on top of a monster, which is something that does not occur in other
 commercial Doom games).  Some monsters on some map levels are "blind" or
 "deaf" where equivalent PC Doom II monsters are not.  A monster's "sensory
 range" is foreshortened in this game (monsters cannot see or hear as far as
 they can in PC Doom II or most other Doom games).  An active monster may halt
 in place if enough distance accrues between the player and monster.  Monsters
 can remain inactive even while being attacked by a player at long distances.
 When monsters are killed, their corpses will flicker and disappear after a
 brief delay.  Arch-Viles may resurrect killed monsters even after the monster
 corpses have disappeared.  Mancubus monsters are not able to aim vertically,
 and will always launch their fireballs in a wide, predetermined pattern.
 Revenants will only fire homing missiles, which are smokeless (in PC Doom II,
 Revenants can fire 2 missile types: a smoking homing missile, and a smokeless
 non-homing missile).  Unlike most other Doom games, monsters such as Imps or
 Demons cannot scratch or bite a player from very high/low adjacent areas.
 Floating/flying monsters may not always change altitude to attack a target,
 or may fail to rise again after dropping in pursuit of a target.  Monsters
 may continue to try to attack killed players.  Some monster sound effects are
 missing, including the standard walking sound effects for Arachnotrons and
 Cyberdemons.  Common bullet-firing sounds are used when the Chaingunner enemy
 fires (in PC Doom II, a shotgun sound is used).  The sounds used during an
 Arch-Vile attack are reversed from sounds used in PC Doom II (in this game,
 the "boom" sound of a completed attack precedes the "burning" sound of an
 attack in progress).  Some player/monster weapons have slightly modified
 firing strengths or rates.  Weapons tend to have less horizontal auto-aiming
 ability, and some projectiles are "narrower", than their counterparts in PC
 Doom II.  In GBA Doom II, a minimal burst of chaingun fire is typically 1
 bullet, versus 2 bullets in most other Doom games.  The function of the BFG
 9000 is somewhat different here than in most other Doom games (the weapon's
 secondary-attack pattern and range has been altered).  Bullet and shotgun
 pellet impact patterns differ somewhat from those in other versions.  Monster
 blood is green instead of red.  Player characters do not bleed when injured;
 their blood-spatter sprites are replaced here by "bullet puffs" (small gray
 sprites used for bullet or shotgun pellet impacts on solid surfaces).  No
 exploding-monster effect (usually seen in PC Doom games when, for example, an
 Imp or Former Human is hit by a rocket).  Rocket explosions and plasma bursts
 can trigger impact-activated switches (in most other Doom/Doom II games these
 projectiles will not affect switches).  Unlike other Doom games, close-range
 explosions caused by player rockets will not push against the player.  In
 this game muzzle flashes from player weapons do not brighten nearby surfaces,
 as they do in other Doom/Doom II games.  Unlike the PC Doom games, players
 can change lateral direction and speed while falling/moving through the air.
 Hitting the Activate/Use button can still trigger the "grunt" sound effect,
 even when the player character is nowhere near a wall, switch, or door.
 Certain messages in this game, such as "Find the switch to open this door",
 do not appear in other Doom games.  Some surfaces with 1-way transparency are
 used in this game (a feature missing from many other non-computer versions).
 "Secret areas" are usually announced (via on-screen messages) as a player
 character enters them.  Monsters which are killed by other monsters are not
 included when calculating the Kills score (in all other Doom games, monster
 deaths are attributed to players regardless of how the kill occurred).  Newly
 acquired weapons or ammo items contain a doubled amount of ammunition at all
 skill levels (in the PC games, the standard amount of ammo for each item is
 doubled when playing at the lowest or highest skill levels).  In GBA Doom II,
 almost all retrievable items on a given map level are tallied in the Items
 score (in most other Doom/Doom II games, many retrievable item types are not
 tallied).  Unlike PC Doom games, a player may pick up more than one Computer
 Map item.  The tally screen shows both the time spent on the map, and the
 map's Par Time.  All major items and power-ups will re-spawn in Deathmatch,
 including Invulnerability Spheres, Blur Artifacts and Megaspheres (in PC Doom
 games, not all item types will re-spawn).  Some symbols and images from the
 secret maps in PC Doom II are altered in the equivalent GBA Doom II maps.
 Objects suspended from ceilings (bodies or body parts on chains, etc.) do not
 appear, as they do in the equivalent PC Doom II maps.  In most Doom/Doom II
 games the plasma rifle is swung up and to the side for a moment at the end of
 a firing sequence; in this game the weapon always faces forward.  Some item
 names are misspelled (MEDIKIT spelled MEDKIT), or are spelled differently in
 different places (ARMOR/ARMOUR).

 Notes: In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally
 screens, and "'O' OF DESTRUCTION!" in the Automap.
 In GBA Doom II, maps "INDUSTRIAL ZONE" and "THE CHASM" are each split into 2
 separate maps (parts "A" and "B").
 The map numbers used here for GBA Doom II maps are for reference only, and
 are not displayed in the game.

12. TAPWAVE ZODIAC DOOM II
==========================
o The term "Zodiac" in this document applies to either of 2 similar handheld
 Tapwave devices: Zodiac 1 and Zodiac 2.

o A Tapwave Zodiac 2, model T2907USA ("first edition"), was used as the test
 system for the Zodiac Doom II game described in this document.

o Pros: Zodiac Doom II is a nearly direct copy of the v1.9 PC Doom II game, and
 so includes all of the original PC maps and monsters, and almost all of the
 original art, textures, music, etc.  This Zodiac game has fewer changes or
 omissions than GBA Doom II and many other non-computer Doom/Doom II games.
 Decent gameplay and screen-refresh rate.  A game in progress may be saved at
 any point and restored later to the same point.  Saved games retain copious
 information (player location, health, weapon, ammo and armor status, live/
 dead status of all monsters on the map level, etc.).  Game supports 9 screen
 sizes, which also allows the first-person view to be expanded to fill the
 entire screen.  Some analog-control customization allowed ("Move sensitivity"
 and "Turn sensitivity" adjustment options).  Includes an "Autorun" option
 (player always runs).  Games played at "Nightmare" skill include re-spawning
 monsters (a feature otherwise found only in PC, Xbox and Xbox 360 games).

o Cons: No multiplayer ability.  Although analog-control sensitivity can be
 adjusted, precise movement of the player character can be difficult to
 maintain (for example, it can be overly easy to pivot while attempting to
 move in a straight line).  Some infrequently-encountered flaws exist in the
 original commercial PC Doom II game which were ported unchecked into this
 game, including a program bug that creates nearly-intangible monsters, and a
 bug that can allow a player character to become trapped partially inside
 solid objects when reloading saved games.  Save-game files are stored in RAM,
 and so are preserved only if the RAM remains powered (power can diminish even
 while the unit is "off"), or the files are manually copied to separate media.
 Weapons are cyclic-access only, and weapon choices can be cycled in only one
 direction.  Occasional errors occur when cycling through available weapons
 (weapon cycle may "wrap around" at the wrong point, etc.).  Map name/number
 is not displayed on the Automap screen.

o Miscellaneous: Port by MachineWorks NorthWest LLC.  Memory-card format (SD
 type); formerly also available as a direct download from www.tapwave.com.  32
 map levels, all of which are found in PC Doom II: Hell on Earth.  No "Attract
 mode"; no demo games.  Some sound effects in this game are "pitch shifted" at
 random, which adds some variety to game sounds (this is a feature found in
 the earliest PC Doom releases, but later abandoned).  Cheat codes are allowed
 in games played at "Nightmare" skill.  A "walk through walls" cheat code is
 included (a cheat otherwise found only in the original PC games, and in Apple
 iPhone/iPod Doom).

13. MICROSOFT XBOX CLASSIC DOOM GAMES
=====================================
o The Xbox game "Doom 3: Limited Collector's Edition" includes the bonus games
 Ultimate Doom: Thy Flesh Consumed, and Doom II: Hell on Earth.  The Xbox game
 "Doom 3: Resurrection of Evil" includes those same two classic games, and an
 additional Master Levels game (essentially an extra mapset for Xbox Doom II).
 This document addresses the classic Ultimate Doom and Doom II games for Xbox;
 For more information about various Master Levels games/Episodes/maps, access:
 http://classicdoom.com/fdoomcmp.htm

o A Microsoft Xbox, model F23-00097, equipped with one standard Xbox controller
 (model K04-00001), was used as the test system for the Xbox Ultimate Doom and
 Xbox Doom II games described in this document.  For testing split-screen
 multiplayer games, additional controllers (K04-00001, K86-00001, third-party)
 were added to the system.

o Pros: The Xbox Ultimate Doom and Doom II games are nearly direct copies of
 the equivalent v1.9 PC games, and so include all of the original PC maps and
 monsters, and almost all of the original art, textures, music, etc.  In
 general, these games have fewer changes or omissions than most other console
 Doom/Doom II games.  Both games support split-screen Deathmatch/Cooperative
 gameplay for 2 to 4 players.  Very fast gameplay and screen-refresh rate in
 both single-player and multiplayer games.  Single-player games in progress
 may be saved at any point and restored later to the same point.  Saved games
 retain copious information (player location, health, weapon, ammo and armor
 status, live/dead status of all monsters on the map level, etc.).  Games
 support 9 screen sizes, which also allows the first-person view to be
 expanded to fill the entire screen.  Games played at "Nightmare" skill
 include re-spawning monsters (a feature otherwise found only in the PC and
 Xbox 360 games, and Zodiac Doom II).

o Cons: Some infrequently-encountered flaws exist in the original commercial PC
 Doom/Doom II games which were ported unchecked into these games, including
 areas on some levels where players may become inadvertently trapped, a
 program bug that creates nearly-intangible monsters, a bug that can allow a
 player character to become stuck partially inside solid objects when
 reloading saved games, and a bug in Doom II where the game can crash if a
 map-30 save-game file is reloaded.  In addition to the flaws ported from the
 PC games, the Xbox games may sometimes freeze or crash where the original PC
 games would not.  Cheat functions can be accidentally implemented during play
 (some common gameplay actions have button-use patterns that match certain
 cheat codes).  No controller customizing allowed.  No built-in ability to
 adjust sound effects volume or music volume.  No ability to independently
 scroll the Automap (the Automap display is always in "Follow mode").  No
 ability to select skill level for multiplayer games; Deathmatch and Co-Op
 games can only be played at skill 3 ("Hurt Me Plenty").  Items will not
 re-spawn in Deathmatch games.  Weapons are cyclic-access only (although
 weapon choices can be cycled in both directions).  Some enemy types are not
 in "fast" mode in games played at "Nightmare" skill.  A player cannot get a
 100% Kills or Secret score on Ultimate Doom map E4M1 ("HELL BENEATH"), due to
 a switch that was disabled when this map was ported from PC Ultimate Doom.
 No "Gamma Correction" feature or equivalent (however the first-person view
 tends to be brighter than in some other console versions).

o Miscellaneous: Ports by Vicarious Visions.  Xbox DVD format.  The Ultimate
 Doom game contains 37 map levels, 1 of which is not found in PC Ultimate
 Doom; The Doom II game contains 33 map levels, 1 of which is not found in PC
 Doom II: Hell on Earth.  Graphics resolution and quality are virtually
 identical to the original PC games.  In "split screen" mode, the individual
 player screens retain the aspect ratio of a full-sized screen; As such, the
 first-person views do not expand to fill all available space on the display
 device for 2- or 3-player games.  All Episodes of the Ultimate Doom game use
 only one sky/background texture for each map (versus a variety of backgrounds
 in the PC game).  Music tracks in both games play at a slightly different
 rate than the equivalent tracks in the original PC games.  When cycling
 through weapons in Doom II, the double-barrelled "Super Shotgun" weapon slot
 is located between the chain saw and fist (in PC Doom II games, both shotgun
 types share a weapon slot between the pistol and chaingun).  The player can
 select the fist weapon at any time, whether or not a chain saw or Berserk
 Pack has been acquired.  In the first 3 Episodes of the Ultimate Doom game,
 Phobos/Deimos/Hell landscapes are used as the background for the tally
 screens between map levels, showing the player's progress through the various
 stages of each Episode (this art is omitted from some other non-computer Doom
 versions).  Some sound effects in both games are "pitch shifted" at random,
 which adds some variety to game sounds (this is a feature found in the
 earliest PC Doom releases, but later abandoned).  Cheat codes are allowed in
 games played at "Nightmare" skill.  The bonus maps in these games originally
 appeared earlier as third-party WAD files for the PC games.

14. MICROSOFT XBOX 360 DOOM
===========================
o "Doom" for the Xbox 360 is available as a download through Xbox Live Arcade
 (a subcomponent of Xbox Live, an online service for Xbox and Xbox 360 game
 consoles).  The game is offered in 2 forms: "Free Trial", where players can
 try the game's first map for free, and "Full Game" (which currently costs a
 one-time payment of 400 Microsoft Points, about 5 US dollars).

o Although this Xbox 360 game is titled "Doom", the actual product is the
 4-Episode update/reissue of Doom, called "The Ultimate Doom".

o A "Premium" Microsoft Xbox 360, model MSK-XBOX360CONSOLE(B), equipped with
 one standard Xbox 360 wireless controller (model X809478-001), was used as
 the test system for the Xbox 360 Doom game described in this document.  For
 testing split-screen multiplayer games, additional identical controllers were
 added to the system.  For testing online multiplayer games, the console was
 connected through the Xbox Live service to an identical console.

o Pros: This Xbox 360 game is a nearly direct copy of PC Ultimate Doom v1.9,
 and so includes all of the original PC maps and monsters, and virtually all
 of the original art, textures, music, etc.  In general, this Xbox 360 game
 has fewer changes or omissions than most other console Doom/Doom II games,
 including the earlier Ultimate Doom port for Xbox (bundled with Xbox Doom 3
 games).  Graphics resolution for this game is higher than that of any other
 commercial Ultimate Doom game (including the original PC version), improving
 the sharpness and detail of sprites and textures at longer ranges.  Supports
 split-screen Deathmatch and Cooperative gameplay for 2 to 4 players, and
 full-screen Deathmatch/Cooperative games over Xbox Live.  Very fast gameplay
 and screen-refresh rate in both single-player and same-console multiplayer
 games.  Single-player games in progress may be saved at any point and
 restored later to the same point.  Saved games retain copious information
 (player location, health, weapon, ammo and armor status, live/dead status of
 all monsters on the map level, etc.).  Game supports 11 screen sizes (but
 does not allow the first-person view to be expanded to fill the entire
 screen).  Games played at "Nightmare" skill include re-spawning monsters (a
 feature otherwise found only in the PC, Xbox/Xbox 360, and Zodiac games).
 As an Xbox Live product, online patches or upgrades may become available for
 this game at any time.  Game supports 10 save-game slots per storage device,
 and the storage device can be specified or changed when saving/loading games.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC
 game which were ported unchecked into this game, including areas on some
 levels where players may become inadvertently trapped, and a program bug that
 can allow a player character to become stuck partially inside solid objects
 when reloading saved games.  In addition to the flaws ported from the PC
 game, this Xbox 360 game may sometimes freeze where the original PC game
 would not.  No controller customizing allowed.  No ability to independently
 scroll the Automap (the Automap display is always in "Follow mode").  Online
 multiplayer games are currently only available to paying members of Xbox Live
 Gold; the free/Silver membership does not support online play.  Deathmatch
 games are confined to single maps (exit switches/portals are deactivated).
 Weapons are cyclic-access only (although weapon choices can be cycled in both
 directions).  Some enemy types are not in "fast" mode in games played at
 "Nightmare" skill.  No "Gamma Correction" feature or equivalent (however the
 first-person view tends to be brighter than in some other console versions).

o Miscellaneous: Port by Nerve Software and Vicarious Visions.  Available as a
 download (about 23 megabytes) through the Xbox Live online service.  36 map
 levels, all of which are found in PC Ultimate Doom.  As with other Xbox Live
 titles, this game supports the "Achievements" system, which allows players to
 track various accomplishments in the game, for both themselves and other
 players of the game on Xbox Live.  In "split screen" mode, the individual
 player screens retain the aspect ratio of a full-sized screen; As such, the
 first-person views do not expand to fill all available space on the display
 device for 2- or 3-player games.  In Cooperative-mode games, whenever one
 player acquires a key, the same key appears in the inventory of all other
 players.  A player can select the fist weapon at any time, whether or not a
 chain saw or Berserk Pack has been acquired.  In the first 3 Episodes of the
 game, Phobos/Deimos/Hell landscapes are used as the background for the tally
 screens between map levels, showing the player's progress through the various
 stages of each Episode (this art is omitted from some other non-computer Doom
 versions).  Music tracks are remastered in 5.1 Surround Sound, and so sound
 marginally different than the equivalent tracks in the original PC game.
 Some sound effects in this game are "pitch shifted" at random, which adds
 some variety to game sounds (this is a feature found in the earliest PC Doom
 releases, but later abandoned).  No built-in cheat codes.

 LIMBO" in the tally screens, and "LIMBO" in the Automap.

15. MICROSOFT XBOX 360 DOOM II
==============================
o Doom II for the Xbox 360 includes 2 games/Episodes in a single download via
 Xbox Live Arcade (a subcomponent of Xbox Live, an online service for Xbox and
 Xbox 360 game consoles).  This download is offered in 2 forms: "Free Trial",
 where players can try the first map of either Episode for free, and "Full
 Game" (which currently costs a one-time payment of 800 Microsoft Points,
 about 10 US dollars).

o A "Premium" Microsoft Xbox 360, model MSK-XBOX360CONSOLE(B), equipped with
 one standard Xbox 360 wireless controller (model X809478-001), was used as
 the test system for the Xbox 360 Doom II game described in this document.
 For testing split-screen multiplayer games, additional identical controllers
 were added to the system.  For testing online multiplayer games, the console
 was connected through the Xbox Live service to an identical console.

o Pros: This Xbox 360 title features a nearly direct copy of PC Doom II v1.9,
 (and so includes all of the original PC maps and monsters, and virtually all
 of the original art, textures, music, etc.), and also includes an additional
 and separate 9-map Episode, "No Rest for the Living".  In general, Xbox 360
 Doom II has fewer changes or omissions than other console/handheld Doom II
 games, including the Doom II port for Xbox (bundled with Xbox Doom 3 games).
 Graphics resolution for this game is higher than that of any other commercial
 Doom II game (including the original PC version), improving the sharpness and
 detail of sprites and textures at longer ranges.  Supports split-screen
 Deathmatch and Cooperative gameplay for 2 to 4 players, and full-screen
 Deathmatch/Cooperative games over Xbox Live.  Very fast gameplay and
 screen-refresh rate in both single-player and same-console multiplayer games.
 Single-player games in progress may be saved at any point and restored later
 to the same point.  Saved games retain copious information (player location,
 health, weapon, ammo and armor status, live/dead status of all monsters on
 the map level, etc.).  Game supports 11 screen sizes (but does not allow the
 first-person view to be expanded to fill the entire screen).  Games played at
 "Nightmare" skill include re-spawning monsters (a feature otherwise found
 only in the PC, Xbox/Xbox 360, and Zodiac games).  As an Xbox Live product,
 online patches or upgrades may become available for this game at any time.
 Game supports 10 save-game slots per storage device, and the storage device
 can be specified or changed when saving/loading games.  Gameplay sessions are
 automatically recorded (although recordings can be flawed), and the top ten
 highest-scoring sessions on the Xbox Live Leaderboards are preserved, and can
 be watched at any time from the Leaderboard menu screen.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC
 game which were ported unchecked into this game, including areas on some
 levels where players may become inadvertently trapped, and a program bug that
 can allow a player character to become stuck partially inside solid objects
 when reloading saved games.  In addition to the flaws ported from the PC
 game, this Xbox 360 game may sometimes freeze where the original PC game
 would not.  No controller customizing allowed.  No ability to independently
 scroll the Automap (the Automap display is always in "Follow mode").  Online
 multiplayer games are currently only available to paying members of Xbox Live
 Gold; the free/Silver membership does not support online play.  Deathmatch
 games are confined to single maps (exit switches/portals are deactivated).
 Some enemy types are not in "fast" mode in games played at "Nightmare" skill.
 No "Gamma Correction" feature or equivalent (however the first-person view
 tends to be brighter than in some other console versions).  Recorded gameplay
 sessions ("demos") may desync when replaying, causing player characters to
 appear to move and shoot at random.

o Miscellaneous: Port and additional content by Nerve Software.  Available as a
 download (about 35 megabytes) through the Xbox Live online service.  41 map
 levels, total, 32 of which are found in PC Doom II.  As with other Xbox Live
 titles, this game supports the "Achievements" system, which allows players to
 track various accomplishments in the game, for both themselves and other
 players of the game on Xbox Live.  In "split screen" mode, the individual
 player screens retain the aspect ratio of a full-sized screen; As such, the
 first-person views do not expand to fill all available space on the display
 device for 2- or 3-player games.  In Cooperative-mode games, whenever one
 player acquires a key, the same key appears in the inventory of all other
 players.  In addition to standard cyclic weapon selection, weapons can also
 be selected by category, tapping Up on the D-pad to select shotgun (or to
 switch between shotgun types), Right for pistol/chaingun, Left for plasma
 rifle/BFG 9000, and Down for all others.  A player can select the fist weapon
 at any time, whether or not a chain saw or Berserk Pack has been acquired.
 Recently-recorded gameplay sessions on the player's Xbox 360 will temporarily
 replace the built-in demos that are shown during any idle time between games.
 Music tracks are remastered in 5.1 Surround Sound, and so sound marginally
 different (in addition to being slower) than the equivalent tracks in the
 original PC game.  Many sound effects in this game are "pitch shifted" at
 random, which adds some variety to game sounds (this is a feature found in
 the earliest PC Doom games, but later abandoned).  The red plus-shaped symbol
 on health power-ups has been replaced in this version by a red-and-white pill
 symbol.  No built-in cheat codes.

16. APPLE IPHONE/IPOD TOUCH DOOM
================================
o The terms "iPhone Doom", "iPod touch Doom", "iTouch Doom" and "iPod Doom" in
 this document all refer to the Doom (Classic) game for Apple iPhone and iPod
 touch devices.

o A third-generation 32GB Apple iPod touch ("iTouch"), model PC008LL, was used
 as the test device for the Apple iPhone/iTouch Doom game described in this
 document.  For testing multiplayer games this device was connected wirelessly
 to a second, identical iPod touch.

o Pros: This game is a close copy of PC Ultimate Doom v1.9, and so includes all
 of the original PC maps and monsters, and virtually all of the original art,
 textures, music, etc.  In general, this game has fewer changes or omissions
 than most other console/handheld Doom games.  Multiplayer ability, allowing
 2-4 player Deathmatch and Cooperative games via short-range wireless
 connection.  Extensive control customization allowed.  Comparatively smooth,
 high-resolution graphics produced through dynamic antialiasing.  The
 "pixelation" effect (a drop in graphics resolution seen in other Doom games
 as the player character approaches a surface or object) is notably reduced
 here.  Very good gameplay and screen-refresh rate.  A game in progress may be
 saved at any point (but only a single save-game slot is available) and then
 restored later to the same point.  Saved games retain copious information
 (player location, health, weapon, ammo and armor status, live/dead status of
 all monsters on the map level, etc.).  During a game in progress, weapons are
 direct-access (after a single tap on the touchscreen to bring up a weapons
 menu).  Built-in ability to listen to alternative audio on the device (music
 files, etc.) while playing the game.  In the status bar, current ammo levels
 and ammo limits are always displayed for all weapons (in some console Doom
 games, only the currently selected weapon has an ammo level displayed).  On
 the Automap screen, zooming and scrolling functions are very quick and
 responsive.  Widest number and variety of built-in cheat codes among all
 commercial classic Doom games.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC
 Doom/Ultimate Doom game which were ported unchecked into this game, including
 areas on some levels where players may become inadvertently trapped.  No
 documentation, background story, or gameplay information is included with the
 download.  Because the touchscreen itself is used as a control interface,
 some part of the first-person view is always obscured during active gameplay.
 Only one save-game slot is available, and this slot is automatically used
 whenever a player moves between map levels, overwriting any manually-saved
 game.  No ability to play in Automap mode (gameplay is always paused while
 the Automap screen is displayed).  Game App file size is 77MB, which is much
 larger than the equivalent PC software.  When running, the game will override
 the device's optional "Auto-Lock" and "Passcode Lock" settings, which put the
 device in a sleep/password-protected mode if it is unattended for a specified
 amount of time.

o Miscellaneous: Port by John Carmack and the PrBoom project team.  Available
 as a 77MB downloadable application (or "App") via Apple Inc.'s iTunes/App
 Store.  36 map levels, all of which are found in PC Ultimate Doom.  Unlike
 most other commercial Doom games, a player may choose any map to start a new
 game on.  This game keeps a running tally of certain player achievements per
 map, including whether or not the player played that map, got a 100% Kills or
 Secrets score, and/or beat that map's Par Time.  No "Nightmare" skill level.
 Automap screen provides more color-coded information than the original PC
 games, including specific color designation for key-locked doors, secret
 areas, and differentiation for object types when using Automap cheat codes.
 In this game, "blurred" objects are translucent and faded, but otherwise
 maintain their normal colors and surface features (in the PC games, "blurred"
 objects, when visible, are a translucent gray, with a flat, flowing/scrambled
 surface).  A player can select the fist weapon at any time, whether or not a
 chain saw or Berserk Pack has been acquired.  In the first 3 Episodes of the
 game, Phobos/Deimos/Hell landscapes are used as the background for the tally
 screens between map levels, showing the player's progress through the various
 stages of each Episode (this art is omitted from some other non-computer Doom
 versions).  Some sound effects in this game are "pitch shifted" at random,
 which adds some variety to game sounds (this is a feature found in the
 earliest PC Doom releases, but later abandoned).  An option has been added to
 allow a player killed in single-player mode to restart on the map with some
 additional ordnance.  Unlike some other Doom games, a player cannot switch to
 any weapon in the inventory that has zero ammo.

 Notes: "N/A" is "Not Applicable"; "Data" is any gameplay information that can

 Unlike other console/handheld Doom games, Doom 64 is not a copy of a PC game.
 GBA Doom II uses 2 separate "half-maps" for each of 2 copied PC Doom II maps.
 Some features in some game versions may require additional hardware/software,
 broadband access, third-party devices, controller adjustments or cheat codes.

 Notes: Map equivalency is based on general map layouts, not map names.
 (Examples: The PSX "HELL KEEP" map is not considered a match for the PC "HELL
 KEEP" map, as the two map layouts are completely different; And although the
 Jaguar game has no map named "FORTRESS OF MYSTERY", the Jaguar's "DIS" map
 layout does match that of the PC "FORTRESS OF MYSTERY" map.)
 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.

 Notes: Map equivalency is based on general map layouts, not map names.
 (Examples: The PSX "HELL KEEP" map is not considered a match for the PC "HELL
 KEEP" map, as the two map layouts are completely different; And although the
 Jaguar game has no map named "FORTRESS OF MYSTERY", the Jaguar's "DIS" map
 layout does match that of the PC "FORTRESS OF MYSTERY" map.)
 The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to a
 "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.

 Notes: "PC DOOM GAMES" includes Doom 1, Ultimate Doom, Doom II, and Doom 95;
 "XBOX DOOM GAMES" includes Ultimate Doom, Doom II and Doom II Master Levels.
 The SNES and Xbox 360 games have no built-in cheats so are not included here.
 The "sound mix" ("high-resolution mixing") code, the "mass kill" ("destroy
 all monsters") code, and the "quiet mode" ("monsters cannot detect quiet
 player") code in the PC-games category indicate PC games played with Doom 95.
 In PSX and Saturn Doom, the add-ammo code only adds keys if they can be used.
 In 3DO Doom, a player cannot warp to another map level during a game in
 progress; However, a cheat code is available that allows a player to start
 new games on any map except map 24.
 In PSX and Saturn Doom games, maps 55 through 59 cannot be warped to from any
 map.  In Doom 64 a player may only warp to maps 1 through 27, or warp to any
 current map to restart on it.  In GBA Doom a player can only warp to the next
 map from the current map, or warp 10 maps beyond the current map.  In the
 Xbox games secret/bonus maps are not accessible via the Warp/exit-level code.
