How to get Ammo Mods and use them effectively
You can enhance your Primary and Melee weapons with an Ammo Mod, adding a powerful elemental effect to your arsenal. Mods are acquired through the Arsenal Machine using Salvage, a resource earned during gameplay.
While only one Ammo Mod can be equipped per weapon at a time, you can swap to a different mod whenever needed, allowing for tactical adaptability to suit different enemies and scenarios.
Dead Wire or Cryo Freeze are great for efficient horde management in the early rounds, while Brain Rot can distract zombies and help with tougher waves as you progress.
For rapid enemy elimination, choose Napalm Burst or Shadow Rift. If your priority is boosting survivability for yourself and your team, Light Mend is the ideal choice.
Pair your Ammo Mod with the Elemental Pop Perk-a-Cola for random mod activations while shooting enemies.
