XPilot

XPilot is an addictive networked multiplayer space-shooter for the X Window System and Windows, modeled after such arcade classics as Asteroids and the Commodore 64's Thrust. This game takes it a step further, though, with an extemely detailed physics engine, enough weapons to bind to almost every key on your keyboard, and network play in any of three modes: deathmatch, team play, and racing. The myriad of keys one has to learn to fly effectively and the relative difficulty of controlling your spaceship pose a steep learning curve for newbies, but once basic control is mastered, it's awesome.
