In Dead Rising 2: Off The Record for the PC, PS3, and Xbox 360, the psychopath costume will not only make you look scarier, it will also you to do more damage with hacksaw movie type weapons (machetes, chainsaws, knives, cleavers, etc.).

To get the Psychopath Clothes, you need to defeat Carl in the Mail Order Zombrex mission.
