Today, developer Saber Interactive has launched its 'Battle of Arizona' update for World War Z: Aftermath, bringing a brand-new HordeXL map to the co-op Xbox Game Pass zombie-slaying adventure.

The new horde mode arena, which takes place in Phoenix, AZ, comes as part of the team's latest update since the game's next-gen upgrade. That upgrade added HordeXL - a wave-based mode that features over 1,000 zombies per-wave on Xbox Series X|S!

"Battle of Arizona” introduces a brand-new map for the massive Horde Mode XL (playable on Steam, Epic Games Store, PlayStation 5 and Xbox Series X|S). Set in an abandoned military museum in Phoenix, this latest map takes the war against the swarms to challenging new extremes. Do you have what it takes to hold the line against impossible odds?"

Alongside this new map, the team is launching a fresh premium DLC called the 'Desert Defenders Weapons Pack', and a bunch of free quality-of-life updates for the rest of the game. We'll drop some more information on those QOL changes down below:

  • New Power-up – Improving Bags: Discover all-new Improving Bag power-ups on PvE and Horde Mode maps for a crucial advantage in the heat of battle! Arm yourself with a variety of bonuses, including a unique boost to strikes, increased ammo capacity, and an additional equipment slot.
  • Class Swapping in Horde Mode and Horde Mode XL: Players can now change their class once during each preparation wave, giving you a chance to adjust your tactics in a pinch!
  • Custom Player Portrait Frames: Show off your accomplishments with new customizable player portrait frames, which are displayed in lobbies and on the scoreboard.
