Alien Arena 2006: Uranium Edition for Windows

It includes 34 maps, five modes of gameplay (DM, TDM, CTF, All Out Assault, and Deathball), six mutators (instagib, rocket arena, low grav, vampire, regen, and excessive), 8 weapons (each with an alternate firing mode), and 9 player characters to choose from - all wrapped up in a retro sci-fi theme. Uranium Edition now includes a level editor, and the brand new Galaxy server browser, which also includes an IRC client to connect you to the channel where players can meet and plan clan wars and matches.
