Time Splitters 2
Release date: 2002
Allowing you to go anywhere from the Wild West to the 25th century, TimeSplitters 2 was a first-person shooter wherein you were tasked with defeating a group of aliens bent on altering the course of human history. What really drew people to this game was its focus on its multiplayer aspect, with some critics calling it the best multiplayer FPS that the PS2 had seen yet. On top of that, there was a split-screen co-op mode that allowed you and a friend to take on the campaign together. Never a bad idea to have a buddy by your side when you're hopping around in the fourth dimension.
