  • Rogan Costume

    Go through original mode, but at the begining select the 2.0 bullets and Double score items. Play through original mode, rescuing all civillians except for the one on level 4 (the guy the Zombie is holding on to). Then beat the game. You'll end up in a Secret room. In the trunk is a Rogan Costume and an Infinite Credits icon.
