OnLive—the subscription service that lets you play a host of games on the cheap, regardless of your hardware—wants to scare their supporters, in the best way possible. They're giving away free copies of Frictional Games' indie-horror gem Amnesia: The Dark Descent, from now until 9pm PST tonight. All you have to do to snag one of the scariest games of all time is register at this link, download the free demo, then enter the promo code "THANKYOU" when it expires.

If you've somehow managed to miss playing this ingeniously-paced thriller (or you've been building up the courage to take a crack at it), now's the perfect time to pick it up. It's one thing to play a game in the dark, headphones on, terrified to move an inch further in fear that you might mess yourself when an invisible demon with a gaping mouth starts chasing you. It's another to be doing those things completely free of charge.
