Highly original first-person shooter that plays more like a tactical turn-based game than traditional FPS. Everything moves only when you move and at the same speed, and your job is to predict enemy movements and take them out one at the time. Most of the time you are surrounded and at great disadvantage. Gameplay is crazy fun, and with more depth could carry a much longer game. It's really more like a tech demo than a fully realized game, and story mode takes about 90 minutes to complete.
