On January 1, 2012, Microsoft will remove firearm props it deems unsuitable for Xbox Avatars. What does that entail? Your guess as good as ours, since our request for a comprehensive list is still working its way through the machine. What we do know is that Gears of War weapon props are out
"Xbox Live Marketplace has updated its policies to provide further clarity for third-party publishers submitting content for approval. This includes details about weapons such as firearms. Xbox Live has always reserved the right to reject or expire from the marketplace any type of weapon prop content that is deemed unsuitable for its general audience," Microsoft informed us in a statement. "Because the Xbox Live Marketplace is accessible to members of all ages, it is important our policies clearly address what content is available to all. This policy provides additional clarity to publishers in advance of the content review process."
Since items purchased in these final moments of 2011 will still be accessible to your Avatar after the content is yanked, take this as the final reminder to grab any Avatar prop "weapons," "firearms" and "gun-like" content before it's pulled.
