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.
