As part of their Summer Sale, GOG’s offering a free copy of Magrunner: Dark Pulse for 24 hours (the game will be available for free until June 19 2014 at 12:59 AM.) Apart from the freebie GOG features 30 game deals and some flash deals, so if you want to add more games to your digital library, it doesn’t get better than this.
For the uninitiated, Magrunner: Dark Pulse is a first-person physics-based puzzle game that shares many similarities with Valve’s Portal and H.P. Lovecraft. In my review, I called Magrunner: Dark Pulse a title that “will catch your attention right from the beginning and won’t let it go until the credits start rolling.”
