Alien Arena 2007 is a standalone game based off of the Quake II/III source that combines the classic sci-fi atmosphere of CodeRED with the tournament style deathmatch of Q3A and UT2k4. With major graphical enhancements such as hi-res 24/32 bit tga textures, light blooms, real time lights and shadows, stainmaps, textured particles, shaders, and reflective water, Alien Arena brings the venerable Quake II engine into modern gaming. The engine also includes mutators, adjustable effects, bot skill settings, and fully configurable deathmatch, team deathmatch, CTF, All Out Assault, Team Core Assault, and Deathball games.

The game features all original artwork, with player models in the 2000-4000 poly range, hi-res textures, and music by PuzzleFighter and WhiteLipper. There are currently 35 maps, loaded with weapons(each having an alternate firing mode) and all new powerups.
