Manipulating time, has been done so many times before. But on timeshift, it has been done exceptionally well.

User Rating: 8 | TimeShift (2007) PC
It offers nothing new or revolutionary, just plain shoot-em up FPS with a time manipulation twist.
You can pause slow down or rewind time. there are puzzles throughout the game that have to be solved using time manipulation.
You can also use it (of course) when you are outnumbered by enemies, for example pause time, kill them all...start time again and watch them all drop dead!
Or steal their weapons and watch them looking around confused as to what just happened.
Your health is embedded into the suit you are wearing and it recharges regularly so there is no need of health packs etc.
Your time manipulation energy also runs out and recharges automatically.
Story line is mediocre but who cares??
I skip the story line videos anyway....
Its a fun game and a must play for an FPS fan.
