User blog comment:Deathmanstratos/Some Call of Duty: Advanced Warfare singleplayer background information revealed/@comment-24001421-20140505021415/@comment-2080691-20140506034637

In my opinion this information looks reliable. I'd be surprised if it didn't have a co-op mode of some sort. That's kinda become the standard for COD's since WaW, it gives players something to do if they get tired of multiplayer and want a more strategic game mode. I doubt it will be like Zombies or Extinction though.
