Man... look at those idiots.

Zoey was out in the middle of the street, trading shots with a toxic trooper. Mustard was safely watching the showdown from the second floor window of his gas station fort. He was glad to be up here and not down there out in the open. He readied his suppressed submachine gun. If they didn't know better by now, they were about to learn a very painful lesson. Zoey finally got the upper hand and was about to deliver the finisher, but looked up and noticed Mustard in the window aiming down at them. She placed a protective wall just as he opened fire.

The oblivious toxic trooper shot the wall down thinking it was placed to stop him, only to get shot in the back and eliminated shortly after. Zoey, clearly out of materials, tried to make a break for it but ran right into Diecast, who must've been looting a house nearby, heard the action, and came looking for a piece. Mustard was more than happy to oblige. However, he only landed a few bullets on this newcomer before the trigger clicked on dry. It was time to scavenge for a new weapon. He reluctantly trudged back down to the lower level and out the door of the gas station.

OK, turtle's out of his shell. Let's see what happens.
