Call of Duty: World at War
Contents: Gun unlock, a week of double XP, and a flask that you couldn't drink out of
This massive package offered fans of the Call of Duty games a chance to get a leg up on the competition by providing instant access to a high-level gun and a week of double XP, dramatically upsetting the balance of the multiplayer experience at launch. The real travesty of this package though was the included flask branded with the game's logo couldn't even be used as it was intended for prop-use only. The thing was literally sealed shut making it a worthless piece of metal you could keep on your desk and that's it.
