Along with Rarity and Pack-a-Punch capabilities, your Primary Weapon can be outfitted with an upgrade known as an Ammo Mod. Obtained in-game via rare Ground Loot, and more specifically at the Arsenal Machine using Salvage you’ve collected as payment, Ammo Mods grant the affected weapon a percentage chance of dealing a special effect upon a successful projectile impact. Only one Ammo Mod can be applied to the weapon at a time, though you can purchase a new Ammo Mod as necessary.

Ammo Mod List

At launch, expect to access the following returning Ammo Mods, each with six Augments to unlock and choose from, to further bolster the following base effects:

  • Brain Rot: Bullets deal toxic damage. Each bullet has the chance to turn a Normal or Special enemy into an ally.
  • Cryo Freeze: Bullets deal frost damage. Each bullet has a chance to slow Normal or Special enemies.
  • Dead Wire: Bullets deal electrical damage. Each bullet has a chance to stun any Normal and Special enemy, generating a field that deals electric damage to nearby enemies.
  • Napalm Burst: Bullets deal fire damage. Each bullet has a chance to ignite Normal and Special enemies.

In addition, expect to access a new elemental power only barely contained with the following Ammo Mod, geared towards controlling dense crowds of the undead!

  • Shadow Rift: Bullets deal shadow damage. Each bullet has a chance to spawn a black hole if striking Normal or Special enemies, warping nearby zombies away and dropping some from the air at high speed.

Gameplay Example

After some encouraging anomalies from the warp inflicted impressive damage to the shambling hordes, research began in earnest on cultivating additional Augments for this Ammo Mod. We ended up going with the following combo of Augments:

Minor Augment:

  • Targeted: Dropped zombies fall on other zombies.

Major Augment:

  • Explosive Rain: Zombies that are dropped from portals will explode on contact with the ground.
