Today Activision revealed that the first chapter of Call of Duty: Advanced Warfare's "Exo Zombies" mode will be included in next year's Havoc DLC pack.

"Some of you may have already noticed something curious if you made it to the end of Riot playing in Exo Survival mode," Activision said in a press release today.Exo Zombies mode will be delivered in chapters, and we'll see the first one in the Havoc DLC pack. At the end of the trailer, we're told the "season" will begin in January 2015 on Xbox Live. Remember, Call of Duty: Advanced Warfare DLC is coming to Xbox platforms first, so you'll have to wait a bit if you're playing on PC or a Sony console.

Activision says more news about Exo Zombies mode is coming in the next few weeks. IGN will keep you updated as we know more
