SUPERHOT is an FPS that has been receiving a pretty significant amount of buzz due to it's unique, signature mechanic in which time moves only when you do. The description for the trailer describes it like this:
SUPERHOT is the first person shooter where time moves only when you move. No regenerating health bars. No conveniently placed ammo drops. It's just you, outnumbered and outgunned, grabbing the weapons of fallen enemies to shoot, slice, and maneuver through a hurricane of slow-motion bullets.
The game released on Steam today, and if you get it before March 3rd, you'll get it for 10% off. Check out the trailer for yourself below.
