New updates are in store for Sledgehammer Games’ near-future shooter, Call of Duty: Advanced Warfare.

On both Xbox One and Xbox 360, the titles first downloadable expansion pack, called Havoc, is now available on the Xbox Live Marketplace (Xbox One, Xbox 360). You’ll also eventually be able to find it in Advanced Warfare’s in-game store.

As highlighted earlier, it introduces four new multiplayer maps to the mix – Core, Urban, Sideshow, and Drift. It also brings back the popular zombie survival mode made famous by the World at War and Black Ops series, but this time with a high-tech twist in what the studio is calling Exo Zombies. You can catch a round-up of new multiplayer and zombies gameplay if you fancy a look. Lastly, gamers will also gain access to the new AE4 directed energy assault rifle and all of its variants.

In addition to the new content, both the Xbox One and Xbox 360 versions of the game have been updated with a 1.7 GB and 35 MB patch, respectively. As of this writing patch notes for either aren’t quite available just yet, but as studio head Michael Condrey hinted during yesterday’s livestream of the new DLC, we know some hefty balance changes are in store for Advanced Warfare’s weapons.
