User blog comment:AntiScootaTwo/"Exo Survival" co-op revealed for Advanced Warfare/@comment-1187559-20140926194510

While it is a bit upsetting that they've gone for a basic survival mode, I don't think it's too fair to just say they're reusing it from MW3. I mean, MW3 wasn't the first game ever to use survival, I mean zombies is just survival against zombies, not a major difference. Also, judging by the amount of co-op related modes out there, there's very little AW could do without being criticised that they copied someone or something else.
