Amnesia the Bunker: A Survival Horror Game

Amnesia the Bunker is set in a World War I bunker that you can freely explore. The puzzles in the game are designed around unlocking new areas within that bunker. And it's just one of those games that has a cool setting that I cannot deny combined with survival horror mechanics, which I am an absolute sucker for. Josh hopes they get to expand on it kind of like high fire rush with a promise sequel.
