Quake2World

Quake2World is a Free, standalone first person shooter video game. Our goal is to bring the fun and excitement of straightforward old-school death-match gaming to a more contemporary platform, and perhaps to a new generation of gamers. Quake2World is multiplayer-only. There is no single-player or offline gameplay mode. If you have no Internet and no friends, Quake2World might not be for you.
