The Gamestop website has stated that if you pre-order a copy of inFAMOUS from their store, you will get some pretty nifty ingame features that you otherwise would not have recieved. By pre-ordering the game from any of their store branches, you will recieve a promotional code that unlocks a new power called the "Gigawatt Blades" which has the player character, Cole, grow blades from his wrists, that are then possibly charged with electricity? I hope so. Apparently these wrist blades will give Cole the power to annihilate all that stands before him, yet still leave him gentle enough to tickle.
