List of preorder bonuses
Pre-order Silent Hill: Downpour before March 13, 2012 at one of the following retailers to get exclusive in-game weapons:
Amazon: $10 credit and two exclusive weapons, a .45 Pistol and a Baseball Bat.
Gamestop: two bonus weapons, a Nail Gun and a Double Axe.
There are a total of six unlockable weapons in the game. Originally, the only way of obtaining them was by using codes supplied by amazon.com and GameStop. However, the codes were leaked and they are universal so any player can use them without having pre-ordered Downpour.
They must be entered into the digital keypads of the green lockers around Silent Hill. There are a total of three lockers. The first is located in a house after exiting Devil's Pit. The player can only use one code in a game. After entering a code, other lockers encountered will be opened and have the weapons in them again, including on a second or subsequent playthrough.
