Remember how pissed off you were when you found out you could only get Juggernaut for Marvel Ultimate Alliance 2 if you preordered from Gamestop? Remember how you wanted to smash your head through a wall in anger? Please remain calm, we're about to tell you how you can stick it to the man and get Juggernaut for yourself without setting a foot inside Gamestop.
Update: Sorry folks, looks like Gamestop pulled the website.
The first think you'll need is a real email address, because Gamestop is going to email you the code. The next thing you need is a Gamestop receipt number. We don't know if any number will do, but the receipt we used was actually used to purchase MUA 2.
The receipt number looks like this: 05317/01 - 011
The same receipt number can be used multiple times - so go right ahead and use that above one if you feel like it. We even managed to snag two codes because we tried two different email addresses to verify. Hint: Google Image Search is your friend.
Finally head to this website and enter some information including that valid email address. We had our codes about 12 hours later.
Do note three things:
1) Supplies are supposed to be limited on these, so hurry up!
2) I imagine Gamestop will catch on eventually, so you might want to try to mix up the receipt numbers.
3) We had issues entering the codes on the Xbox marketplace website, but they worked when entered into the dashboard.
Update: As of 11:28 PM The website has been taken offline. Sorry folks!
