TimeShift is a sci-fi first-person shooter developed by Saber Interactive and published by Sierra Entertainment for Microsoft Windows, Xbox 360 and PlayStation 3 in fall 2007. Timeshift had a very troublesome development, after switching 2 publishers and going through 2 delays. It was finally published by Vivendi after reveiving a complete overhaul and a massive bug fixing together with a major visual improvement.
It tries to be innovative with it's time controling mechanics, but gets dumbed down by repetitive gameplay and a simply bad plot.
Although from the trailer it might seem like Prince of Persia with guns, it isn't.
