Alien Arena 2009 is a freeware online deathmatch game with fast and furious action for Windows and Linux!
The game runs on the CRX engine, and features modern effects such as real-time lighting and shadows, shaders, light bloom, reflective surfaces and much more, while still being able to run on even modest systems.

The game includes a built in, as well as external server browser and chat client. Players can look up their stats online, chat with other players, and become part of a growing community.
