Well i pre-ordered the game and went and collected it. However, i cannot find the nuketown 2025 code. Should i go see my retailers again, which in thise case, is tesco.
Maybe they will email you. Try and send them an email. Or call them whatever works for you
Give them a call and see what they say. They should have given you the code on a card when you picked it up
If you got it from Gamestop, it is usually on the receipt itself.
