Highlights of the latest release include improvements in shadow, weather, and sound effects (including doppler effect), as well as security fixes and recording of first run settings. Two new game levels have been added.
Like many other great 3D shooter games, Alien Arena is based on the Quake II engine and is in some ways similar to Quake III and Unreal Tournament. The game shows off amazing visual effects and offers a rich Sci Fi type environment with dozens of game levels and numerous modes of play, player models, and weapons. You can fight in single player mode against the machine's AI, or connect to a server and play with other people over the Internet.
You can download the latest version from the the Alien Arena home page.
