#5 Amnesia: The Dark Descent
Amnesia: The Dark Descent is another title that was a massive success when it first released in 2010. The game first released as an independent download by developers Frictional Games. Players awake in a dark castle with no memory other than their name and that something is hunting them down. As players lurk throughout the castle to regain their memory they’ll be subjected to the main gameplay element, puzzle solving. However, within the castle are grotesque enemies that not only will kill the player character but also cause their sanity level to decrease. This sanity level acts as a health indicator. If not managed properly, the player will start to witness unsettling events, eventually leading to their death.
