To play Dark Hero Mode, you must select a new game from the main menu. After watching the introduction video, and signing the contract, you will be asked: Pick yes to choose a victorious game save on your memory stick to copy. That savegame will not be deleted, and you can continue playing it. All the weapons, armour and Ka-ching you collected are transferred to the Dark Hero save, even the equipment that cannot be used. In Dark Hero mode, you can only play one mode: Versus Mode. You can use either Ad-hoc or Infrastructure.
