I ended up receiving this game in a grab bag of random used xbox 360 games that I bought last week, and even though it shipped with an online pass code still in the case, it turned out that it had already been used. So, out of curiosity I hit the purchase pass option to see if this game's online pass was the usual $10. Instead it told me that the pass cost negative 1 microsoft point, so OBVIOUSLY I'm gonna get it if they're going to pay me to take it. Then I went to actually buy it and it told me that I had insufficient funds in my account to purchase the pass, because suddenly the price had gone up to 4294967295 microsoft points!
Anybody have a few dollars I can borrow?
