Free during the month of December for Xbox Live Gold members
Microsoft's "Games with Gold" initiative has been picking up steam lately, with two games being offered free of charge to Xbox Live Gold members every month since its inception. I usually don't get to benefit from it due to already owning the titles in question, but late next month I'll be able to snag Shoot Many Robots for free. Rad.
Gold members who don't already own the original Gears of War will be able to experience the game that popularized cover-based third-person shooters during this past generation, in all of its chainsaw-bayoneted glory. For the month of December, Gears of War will be free until the 15th while Shoot Many Robots will be featured from the 16th onward.
