Amnesia: The Dark Descent

Amnesia: The Dark Descent is the latest game from the makers of the Penumbra
series, Frictional Games.  This game puts us in the roll of Daniel, a man who
finds himself trapped inside of a massive castle sometime in the 1830's.  He
has little to no memory of how he got to where he is now.  The only clue is a
letter he wrote to himself prior to losing his memory, explaining that there
is an unstoppable shadow hunting him and that he is to kill a man named
Alexander.

Amnesia is a adventure/horror survival game.  It has placed a large emphasis on
atmosphere and immersion.  It's best to play the game at night, alone, inside
of a dark room, and wearing headphones.  To increase the feeling of
helplessness the game features no weapons and no ways to kill the shadow
chasing after him.
