When I picked up my game from gamestop yesterday I just took it home and didn't play because I was pretty busy. So today I opened it up and found no nuketown code or Double XP like the preorder offer had stated. What gives? I did everything I was supossed to do and I got cheated of two things. They actually were the only reason I did preorder and not just pick it up another time. Anyways I talked a friend into buying me a code of ebay and I payed him back but I'm still missing double XP. Does anyone know when we get it or how to get it? because I don't want to spend another 5-10 dollars on something that did not show up upon arrival as promised.
