Through all my zombie playing i have to give it to the trench gun upgraded aka the gut shot. And the ray gun upgraded with juggernaut, speed cole, and double tap because it give you ma
more ammon if you get in a pinch.
the stg was the first gun i ever upgraded and i wasnt to impressed by it. Didnt have to stopping power. The M1A1 is pretty cool upgraded has a decent punch to it but i recommend the PTRS upgraded holds 7 rounds and can go through 10 zombie at a time its good for when you camp at the trench gun side straight down the alley way.
the waff is a good gun and so is the porters ray gun but only problem is that without juggernaut you down yourself. But with juggernaut they are pretty good but you burn through ammo way to fast with them especially in the later rounds. But everyone has their own opinons isnt that the great part about america.
