"Today Frictional Games, the makers of the Penumbra series, has
released a demo for their upcoming first person survival horror
"Amnesia: The Dark Descent". Players with Windows, Mac or Linux all
get a chance to experience a small slice of the dread and terror
contained in the full game.
"The game begins with Daniel awakening in a desolate Prussian
castle, without any memories to explain his situation. A letter
written by himself, reveals that the amnesia is actually
self-inflicted. The mysterious message urges him to seek out and
kill Alexander, a man residing deep below the castle. Hunted by a
dark shadow, Daniel can see no other way out than to trust his
former self. If he is to save his life and mind, he needs to find
out what it is all really about. It is his only hope for salvation.
A dark descent awaits."
