Your Xbox 360 may be haven for mature-rated gaming with its Grand Theft Autos and its Call of Dutys, but the front-facing dashboard is usable by one and all and it's largely family-friendly. Unless you find excessive product placement offensive, that is. That family friendliness probably why you'll soon no longer be able to buy guns for your Xbox Live avatar.
A post on the Epic Games forums (via Joystiq) reveals that, starting January 1, 2012, the Lancer and Hammerburst Avatar accessories for Gears of War fans will no longer be available for purchase. The date marks the launch of a new Xbox Live policy that will see the removal of "all gun-like avatar items on the Marketplace." You can keep whatever you already own though, so if you've had your eye on that fake, completely useless gun for ages, NOW is the time to ACT!
