Today Saber Interactive has launched the Community Challenge update for World War Z, available now on PC, PlayStation and Xbox.
Community Challenges are a new event which all players can contribute to over seven days, to earn exclusive rewards. There are also seven brand-new and three reworked mutators to face in Challenge Horde mode – including players facing a doppelganger zombie version of themselves.
Seven totally new and three reworked mutators for Challenge Horde Mode lead the charge in today’s Community Challenge update, including:

New Mutators
- Hot Stuff: An unusual Juggernaut appears, taking no fire damage and setting fire with its attacks.
- Cluster Shells: Mortar shells are replaced with cluster shells that explode multiple times but deal less damage
- Doppelganger: During the wave, you’ll be attacked by a zombie version of you
- Fire-resistant: Zombies take no fire damage and don’t burn
- Acid Spit: The Infector’s infestation does constant damage instead of turning you into a zombie
- Effective Defense: Defensive kits have increased ammo capacity and durability, but are more expensive (permanent mutator)
- Overprice: Defense kits cost more
Reworked Mutators
- Epilogue: When the final gates are attacked, gas is released that’s lethal to zombies (Now recharges after five waves)
- Sell–out: Defense kits are cheaper, but you will no longer find items
- Taxes: Defense kits are more expensive, but you can find twice as many items
Today’s update also introduces Community Challenges, a new type of event in which all players participate and contribute. Each challenge has a limit of seven days, and all players who have made the minimum contribution will be rewarded, if successfully completed. These rewards are unique and not repeatable. The Community Challenges are planned to be run several times per update. The prize for the first challenge is a new skin for the MAG5 machine gun.

In addition, Extinction mode has been reworked and is now only available after completing any map on the Insane difficulty. There are currently two episodes in the mode from which to choose, and completing either will unlock a reward. Players will also discover additional rewards for completing Extinction mode, including new skins for the Taiga-12 heavy assault shotgun, Hailstorm MGL, and RPGL4 RPG launcher.
New custom portrait frames are available to unlock starting today, as well.
