A few happy items to touch on as we lead up to Frictional Games release of their immersive survival horror title Amnesia: The Dark Descent next week.

First, Frictional has offered up a multi-platform (PC, Mac and Linux) demo for the title. The trial weighs in around 150 MB and apparently the devs have turned up the sanity mechanics so it’s harder to stay sane. You like your demo difficult right? The file can be found along with a list of mirror sites hosting it via the official site for the game.

Also in related news, Steam has launched its pre-order page for the game, offering 20% off ($4) for those who throw down for the game before its release September 8 on PC and Mac. A 10% discount can be had through other digital outlets and the developer themselves who also offer a Linux version.

Amnesia hits next Wednesday and from what we’re hearing thus far, is shaping up to be an IOTY contender.
