The overall engine and gameplay looks a ton like Advanced Warfare but without the jetpacks - this isn't a bad thing however. Sledgehammer are good devs and that game was great, and the ways they're changing create a class is really daring. They're certainly the COD devs I feel that take the most risks with changing the game. However this is what caused a lot of undeserved hate for "jetpack CODs" where AW wasn't directly a clone of any other game, except maybe of all things, Unreal in it's movement system. So, I don't know how well it will go over with the broader fans when it's out for everyone to take in.
