John Diamond, the lead developer of the open-source Alien Arena game, has emailed in tipping us off that Alien Arena 2011 will be released next week. Alien Arena is a science-fiction first person shooter game that's powered by a modified id Tech 2 game engine. We first reported on Alien Arena 2011 in October when talking about some of the planned features we were informed of, but as of next week it will be available to all Linux gamers (and those on Windows too) as an early Christmas present -- it was just in May that Alien Arena 2010 was released.
Alien Arena 2011 is internally known as Alien Arena v7.50 and it features rag-doll physics using the Open Dynamics Physics Engine, two new maps, updated player models and skins, faster particle rendering, new in-game music, updated/improved shaders, and many other key improvements. According to the early change-log, there are 25 major changes to be found in this updated open-source 3D FPS game.
