GOG's summer sale presses on, and today it's offering a flash deal on Magrunner: Dark Pulse. For the next day (more like 20 hours, to be exact), you can snag the first-person puzzler for zero dollars. Not bad for a game that's less than a year old.
Just visit GOG, log in, and grab your copy. It will be a freebie until 6 AM PT tomorrow.
