World War Z Aftermath marked one of today's biggest Xbox Game Pass additions (we had four new arrivals on Dec. 5), and to coincide with the title's Game Pass inclusion, the team at Saber Interactive has just added even more content to the game.

Yep, the 'Valley of the Zeke' update is out today, featuring a new premium campaign and a bunch of free DLC items for all players. The premium campaign, set in Arizona, will cost Game Pass players an additional $9.99 / £8.39, while the following items are all freebies:


  • New zombie enemy types that appear across all episodes: the Juggernaut, a special zombie unit that relentlessly charges anything and everything in its path, and new military zombies equipped with additional combat armor.
  • Introducing the De50 Heavy Pistol secondary weapon, a large-caliber firearm packing a ton of destructive power.
  • Unleash an array of thrilling mutators for wildly new experiences in Challenge Mode and Challenge Horde Mode! Transform the battlefield by arming auto-turrets with explosive ammo, call your inner cowboy and make everyone wield repeating rifles and revolvers, and more!
  • For PlayStation 5, Xbox Series X|S and PC players, the Rome XL map is now available in Challenge Horde Mode, offering a dynamic environment to navigate and conquer.

There's also an additional paid skin pack out today for $4.99 / £4.19, and if you want to see all of this in action, check out the new update trailer we've included up above. World War Z was a pretty good Left 4 Dead-inspired time when it first launched back in 2019, so we're quite looking forward to jumping into the 'Aftermath' version on Xbox Game Pass!
