Ok I know that there are 3 DLC for the game. One being the flight suit from Gamestop. The second being from Best Buy with the Mayor/Ghoul as playable characters in multiplayer. The third one being the gold proton pack. Now I know that each one comes with a code you have to enter and I have the flight suit and the mayor/ghoul but I was wondering if anybody had the gold proton pack code and can you type it in more than once for it to work.

Those codes are one time use only.

oh ok that's what I thought but I wasn't to sure because somebody gave me a gold proton pack code once but I wasn't to sure if it was right or not so thanks for clearing that up.
