Magrunner: Dark Pulse Free for 24 Hours on GOG.com

As a part of its 2014 DRM-Free Summer Sale special, GOG is currently offering Magrunner: Dark Pulse free for a single day. Released in 2013 by developer Frogwares, Magrunner: Dark Pulse is a Lovecraftian first-person psychics puzzle that follows the story of a megacorporation summoning the Old Ones. Oops! The game plays out as a cross up between Portal and Call of Cthulhu, so if that’s your thing, head over to GOG.com to add it to your library at a 100% discount.
