With only a week left until the release of SOMA, Steam is offering a substantial 100% discount on developer Frictional Games’ spooky hallway light ’em up, Amnesia: The Dark Descent.

At some point between now and tomorrow at 10AM PST, I’d like you to find Amnesia on the Steam Store and add it to your library. There is no better way to prepare your mind, body, soul and sphincter — assuming yours is separate from your body — for the imminent arrival of one of the most anticipated horror games of the year.
