I pre-ordered my game from gamestop. Picked it up 2 days late and found that my game case did not come with a code. So I just bought the season pass for another $50 in hopes I'd get this map but I only got zombies. This is unfortunate, is there any other way I can possibly get this map?
Not at this time. My guess is that it will be released along with one of the DLC packs so they can put it into rotation and everyone can play it.
I'd complain to gamestop, they screwed you over on that... I got nuketown and didn't pre order, simply picked it up at best buy around 7pm on release day
My wife bought the game for me as a birthday present the week it came out (she was supposed to get AC III - grrrr).
She got ut from gamestop and it did have the nuketown code even though it wasn't a pre-order.
So, yeah ... looks like gamestop may have hosed you.
