All upgrades are free.
Your task in this fun zombie game is to keep your baby from those pesky potheads and the smell of their weed by killing them with your guns. Use your hard earned money to buy and upgrade your mighty weapons. Your co-op shooter can also use purchased weapons, but takes time to use it with perfection and a good fire rate.
Use YOUR MOUSE to aim and click LEFT MOUSE BUTTON to shoot. Have fun!
