Terminator 3: War of the Machines is a team-oriented multiplayer FPS from Clever's Games and Atari. It is based on the Terminator 3 universe (having loved The Terminator and hated T2, I haven't seen T3 and can't comment on whether the game follows the movie or not). It takes place in the year 2029, where the machines are attempting to take over the world, and the humans are trying to stop them. You play as a grunt on either side in one of the many battles that occur. Gameplay closely resembles Battlefield 1942.
