The atmosphere is incredible in this game. It was actually pretty damn scary at time and the lighting helps add to this creepy dark atmosphere. The mechanic of the flashlight works really well in making the environment creepier. Since from what I can tell the flashlight is what attracts the zombies to you but is also your only real way of knowing what is going on. So it leads to this cool dichotomy where the flashlight is your main tool of survival but can also be your death sentence. All in all interesting horror game with well executed mechanics.
