In addition to the over 110 costumes that are currently available in Marvel Heroes, two more got added today according to the official Marvel Heroes blog.
Starting today, players will be able to purchase two costumes for two of the characters: Ms. Marvel and Colossus. The new costumes are based on the 1980s-era. Those who have been reading the Marvel Comics way back then, the two new costumes should give you a nostalgic feel to it. If you’re interested, both costumes can be obtained through in-game loot or via the cash shop.
