Warning: You need 3 people to do this glitch I am the founder of this glitch(I think, I found it over 2 weeks ago) and it was stumbled upon by accident if anyone wants to record this or repost this please give me credit. If someone else found it i'll give you credit. First go down to the docks and find the Tommy gun. Next go to the right (in the corner next to the barrels) and get someone to crouch down there Next get the other 2 people to stand infront of the first guy and watch the zombies pile up! Enjoy. This is unlimited ammo as it's right by the tommy gun.
