The promotional Resident Evil: The Darkside Chronicles shirts Capcom printed up for Comic-Con (which takes place from July 23-26) have their own dark side: specifically, the inside. The shirts look nice enough when worn normally: a "let your darkside out" slogan adorns the front amid zombie silhouettes, and the game's logo occupies the back.

But the inside of each shirt has a special graphic printed upside-down, so that when you flip the shirt over your head, you become a zombie. This is the most amazing advance in swag technology we've seen in years. If you want one (and you do, because wow), you'll have to visit Capcom's special Darkside Chronicles demo area at Comic-Con and try out the co-op mode.
