Fancy a free trip into possibly the scariest PC game of all time? Well, Amnesia: The Dark Descent is exactly that from our point of view, and right now, the Amnesia Collection is free on the Humble Store today and tomorrow.

The collection, which comprises of two games – Amnesia: The Dark Descent and Amnesia: A Machine for Pigs – would normally set you back £27 (or $35), but costs absolutely nothing until tomorrow at 6pm GMT (1pm ET in the US).
