Is there anyway to get all the exclusive armors for mass effect 2 for xbox 360?

Game Stop is no longer selling the Collector's edition of Mass Effect 2, but you could pre-order ME2 standard edition from Gamestop and pre-order the CE from Bestbuy or Amazon. You also have to play Mass Effect Galaxies fro Iphone to get something else. You can always take the standard edition back to Gamestop after you get your codes. Supposedly you can get something from drinking Dr. Pepper, but I don't know about that. Good luck, happy hunting.
