Amnesia: The Dark Descent and Crashlands are free on the Epic Games Store.
The deal is part of Epic’s policy of giving away a free game (or two) each week. Anyone with an Epic Games Store account will be able to claim the games to keep, but you’ll only have until May 7th to do so.
To claim the games, just head on over to the Epic Games Store website or open the PC launcher and find the free games tab. Once there, you’ll be able to claim your digital goodies.
