Ammo Mod Upgrades

4/5 - (1 vote)

Unique to Cold War Zombies, added Elemental Ammo types are physically attached to the weapon and appear as a small battery that glows with whatever ammo’s type is equipped. These can be equipped with a Pack-A-Punch Machine, a place to upgrade your weapon for higher fire rate, higher damage, and some cool-looking camo.
