AssaultCube is a FREE, multiplayer, first-person shooter game, based on the CUBE engine by the team at Rabid Viper Productions. Taking place in realistic environments, with fast, arcade gameplay, it's addictive and fun!
With efficient bandwidth usage, it's low-latency and can even run over a 56 Kbps connection. It's tiny too, weighing in at a lightweight about 50 MB package available for Windows, Mac and Linux. On the correct settings, it can even run on old hardware (Pentium III and above).
