Shoot Many Robots, the first original game by Demiurge Studios, is going to be completely free next month in the Xbox Games with Gold program. It will be joined with the original Gears of War.

The first half of December, from the 1st to the 15th, will feature Gears of War, while the second half will bring on Shoot Many Robots. Shoot Many Robots is also available on the PSN, Android, iOS and PC.

December 1st is also the last day that you’ll be able to get Double Fine’s Iron Brigade for free, so make sure you grab that if you haven’t already. Games with Gold is set to come to Xbox One next year.
