“You'd better make up your mind fast. Are you here to buy equipment, or did you just come here to get shot?”
Zack takes care of selling equipment for the Gun Runners in Fallout.
He sells almost all of the various weapons and ammo that is available in the game, except for BBs. He gives a discount to anyone that helps the Gun Runners with the Deathclaw infestation at the Boneyard.
Zack has between 3,000 and 4,000 caps each time the Vault Dweller talks to him, making him very useful for loot selling.
Zack appears only in Fallout.
