If your 360 avatar is in need of some over-priced, officially-licensed attire to help ring in St. Valentine's Day, Microsoft, 2K and THQ have you covered with some BioShock 2 and Red Faction: Guerilla clothing purchases.
They're your standard fare, a mix of game-themed t-shirts and replica costumes from the titles themselves.
I still don't understand why these aren't free; surely wearing this stuff serves as advertising for the product in question, so the more people out there wearing it the better?
