The online PC game retailer GOG is celebrating its 10th anniversary by giving away a free game to anyone who wants it. Between now and October 6, you can head over to GOG and get a free copy of Shadow Warrior 2--a game that normally sells for $40. To take advantage of the deal, all you need is a free GOG account. You can get the free game here.

The giveaway is the result of a poll the company ran earlier in the week that let customers vote on which game would be free to download. The vote was between Shadow Warrior 2, Firewatch, and Superhot. If you were hoping to get one of the other games for free, all is not lost; for a limited time, they're available at sizable discounts. You can get Firewatch for 75% off ($5) and Superhot for half price ($12.50).
