DRW The Gun Shop

The Gun Shop is a scoop in Dead Rising: Chop Till You Drop and an unmarked scoop in Dead Rising.

Dead Rising
First you must go to the Huntin' Shack and then you will fight Cletus Samson. After defeating him, he will run outside of the store and be attacked by a zombified version of James Ramsey.

Chop Till You Drop
The fight is similar to the Dead Rising one. Avoid getting shot at by Cletus and fire at him when he is vulnerable. In this version Cletus does not die. Instead he will agree to sell you guns.

 * Buying and picking up guns will do the same thing, arm you with a gun.
