Get ready for some first-person-shooter action, time-travel style. Raven Software and Activision's latest title Singularity is a sci-fi FPS that gives the player the ability to manipulate time with -- what else? -- a Time Manipulation Device. You'll use your ability to rewind and fast-forward time to manipulate objects, characters, and solve puzzles. Like most good games and tech experiments, Singularity's events are rooted in the Cold War.
