i don't think you actually play these when you set them up because this week is full of issues. the weapons don't do enough damage to have enough ammo to finish the 1st wave. you can overpenetrate, and not miss a shot, but 15 rounds to kill a regular zed is ridiculous. by the 2nd wave you are being swarmed by quarter pounders and since you don't have enough dosh to buy anything useful, let alone ammo...they just run through the entire group. what a joke.
