Modern Warfare 3 finally released on November 10th 2023 and with it came a promotion with Monster Energy. Certain cans of Monster Energy would have a code on the ring pull of the can that you could enter into Monster Energy's website for a code to redeem in-game items such as double XP, weapon wraps and skins as well.
My son has been collecting these and has been able to get quite a few in-game rewards and also quite a bit of double XP.
Have you been collecting and redeeming the codes on the ring pulls from Monster cans?
