Red Eclipse is a total conversion of Cube 2, featuring entirely free
art under CC BY-SA 3.0 or a compatible license. It features many modes
like deathmatch, free-for-all, and capture-the-flag. The game has a
sci-fi theme and has gameplay similar to Quake-based arena games, with
the notable omission of pickups. The game uses OpenGL.

In the past there was a possibility of the game going commercial, so
some files were labelled Omitted to default to the included license.
It was decided that the default license will be CC BY-SA, so from then
on Red Eclipse is completely libre and is now included in Debian main.

Red Eclipse has been converted to the much more advanced Tesseract
engine. Tesseract adds features such as dynamic lighting, improved map
model support, improved specular and normal map rendering, support for
day/night versions, and more.

This is an unofficial Intel OS X Leopard+ port of the original source.
