Elite Killer

Elite Killer is an achievement in Dead Rising 2: Off the Record.

It is awarded once Frank has killed exactly 1337 zombies, which can be done in story mode or sandbox mode. It must be done in one playthrough.

This will unlock the Ninja Outfit for Frank to wear, which he can access back at the Security Room locker.
