For the next couple of days, and if you’re keen on having your nerves tested, the Amnesia Collection is available for the low price of nothing! This comes courtesy of the good people at Humble.
The collection includes Amnesia: The Dark Descent and Amnesia: A Machine for Pigs. By checking out over at Humble, you’ll be provided with a Steam key for Windows, Mac or Linux. So the only requirement is a Steam account.
