As far as FPS games go, Timeshift is un-remarkable. But add in the unique time manipulation mechanic and this game is amazing. I find myself repplaying each area during a single play though just to perform actions differently. Enimies come running out of a room you can't go into, until your reverse time and run in there with them! Frickin Amazing! I bought this when it first came out, purchased a GOG copy to relive the magic. Worth every penny!
