Amnesia: The Bunker

Game description:

First, imagine the picture: people screaming, bullets whistling, shells rumbling. You are running through a trench, and the events are taking place on the battlefield of the First World War. As you kill enemy after enemy, you find that you are out of ammunition and wounded. A death trap could have lived up to its name, but you fought to the last, sacrificing your memory for your life. You must aim, shoot, craft and throw items - this is the only guarantee of your survival in a bunker whose inhabitants do not wish you well. Inaction equals death.
