When you enter a Code from your first purchase you will automatically receive fifteen (15) or thirty (30) minutes of 2XP (Experience Points), dependent upon package size purchased, and one (1) of the following randomly assigned Call of Duty: Vanguard in-game items: a calling card or a weapons charm.
You can redeem multiple Codes to receive multiple hours of double experience, up to a maximum of 40 hours of 2XP or 160 redemptions per Activision account, whichever is reached earlier. Only one Burger King-themed Call of Duty Operator skin is available per Activision account.
