TimeShift is a sci-fi, first-person shooter from Vivendi Games for the PC, Xbox 360 and PlayStation 3.
It was developed by Saber Interactive, the same developers behind the game Will Rock, using a new proprietary engine. A few pieces of Will Rock carry over to TimeShift, from the way gibs are shown to some of the unique weapon designs.
Modern-age scientists have begun to work on time travel. The antagonist Aiden Krone goes back in time using the alpha suit (the suit from the original build of TimeShift) and does not return. When he reaches the past, he remakes the world in his image, creating a dystopia where Krone rules. The anonymous protagonist uses the Beta time travel suit to travel back in time to see how Krone changed time and stop him.
