The Marvel Universe is about to get a whole lot cuter, as Marvel announced on Friday that fans of the PlayStation 3 game Little Big Planet will soon be able to download new Marvel-themed costumes for their in-game characters. The "Sackboys and Sackgirls" can dress up as Iron Man, Spider-Man, Wolverine, Venom, Punisher, Rogue, Ghost Rider, Green Goblin, Mystique and many more thanks to four costume packs that will roll out every week beginning July 7. In addition, Marvel is also unleashing a Marvel Level Kit, "which includes four levels of adventure pitting your Sackpeople against the evil plans of Magneto," according to Marvel.com. The site promises more information and costume art starting tomorrow.
