World War Z: Aftermath’s Waves of Lead update launched on October 5, 2026.

Saber describes the update as free on PlayStation, Xbox, Steam, and Epic Games Store; access to the crossover episode still requires its separate DLC.

The Walking Dead episode in Extinction Mode
The update adds Extinction Mode to The Walking Dead episode. Saber identifies the episode’s locations as the Prison, Alexandria Safe Zone, and Grady Memorial Hospital. The update itself is free, but playing this crossover episode requires ownership of the World War Z x The Walking Dead episode DLC.
Recommended Free Tools
Two new weapons
- BSG-12 Bullpup Shotgun: A new tier-three firearm with its own perks.
- Gas Pipe Wrench: A new heavy melee weapon.
Six heavy-weapon perks
The new perks affect six heavy weapons. Some change how a weapon works while adding a trade-off, such as reduced ammunition capacity.
#1 Best Overall
| Weapon | Perk | Effect |
|---|---|---|
| Chainsaw | Last Exhaust | Grants a three-second camouflage effect when the Chainsaw runs out of fuel. |
| MAG5 machinegun | Pillbox | Prevents grabs while you are aiming. |
| MGL | Cluster Bombs | Replaces grenades with cluster bombs: smaller blasts scatter charges that detonate one second later. |
| Taiga-12 Heavy Assault Shotgun | Dragon Breath Shells | Fires incendiary rounds and reduces ammunition capacity by 30%. |
| BF25 Payload Rifle | Two-layer Bullet | The bullet pierces the first Zeke and explodes after hitting the next target; total ammunition capacity is reduced by 30%. |
| MRL202 Commando Multi-shot Rocket Launcher | White Phosphorus | Fires area-effect incendiary rounds without leaving a burning puddle. |
How the five new mutators work
Mutators change the rules of a session, and their availability depends on the mode. Saber lists them for Private lobbies, Horde mode, or both; Let Them Dance is specifically not supported for The Walking Dead episode.
| Mutator | Gameplay effect | Availability |
|---|---|---|
| Let Them Dance | Regular zombies take more damage from leg shots and less damage from hits to other body parts. | Private lobby and Horde mode; not supported for The Walking Dead episode. |
| Sharp Shards | Explosions from devices and heavy weapons inflict bleeding. | Private lobby and Horde mode. |
| Leaky Backpack | Players slowly lose ammunition while grabbed. | Private lobby and Horde mode. |
| Paranoid’s Reserves | Equipment crates may be booby-trapped. | Private lobby. |
| All-In | Survivors and zombies have one maximum health. Survivors can be incapacitated without a limit, get up faster, and return to combat sooner. | Horde mode. |
