In Dead Rising 2 for the PS3, Xbox 360, and PC, you can unlock the outfit from primary character in the movie Shaun of the Dead.
To unlock the Shaun of the Dead outfit (labeled in the game as Tattered Clothes), you’ll need to kill 1,000 zombies with your bare hands. This will unlock an achievement called Zombie Fu (20 points) and the outfit will be in the closet of the Safe House.
There aren’t any cricket bats to go along with the outfit, but you can toss some vinyl around if you’d like.
