Another Cool Game (Only Multiplayer MODE not Single Mode)

Tremulous is a free, open source game that blends a team based FPS with elements of an RTS. Players can choose from 2 unique races, aliens and humans. Players on both teams are able to build working structures in-game like an RTS. Tremulous is based upon the GPL source release of the Quake 3 game engine. As a result the Tremulous code is also licensed under the GPL. This means that not only is Tremulous free in terms of monetary value, it is also free in the sense that you are free to use and examine it...
