Amnesia: The Bunker, like its predecessor, is a first-person survival horror video game. The game is set in World War I, and the player assumes control of French soldier Henri Clément. Henri is trapped in an underground bunker and hunted by a mysterious but photosensitive monster named “the Beast”. To survive in the bunker, Henri must maintain the base’s power while collecting resources and ammo, which are randomly placed in the game’s map. Henri can also use a revolver, a shotgun, and other throwable items such as grenades and flares to fight against enemies, but ammo is very scarce. The base is dimly lit, and Henri is eventually equipped with a watch that indicates when the generators will run out of fuel. If the fuel runs out, the base will become completely dark and the monster will actively hunt Henri. To solve the problem, the player needs to refuel the generator and use a noisy dynamo flashlight to find his way in the bunker. There are limited amounts of fuel in the bunker, and once all supplies are used up, the player will have to complete the rest of their playthrough in the dark.
