Campaign only review: the plot of a corporation taking over the military sector of almost every government in existence is rather interesting on paper and I am admittedly engaged with Kevin Spacey's screen presence, but the supporting cast, execution of the finer details of the story, and boring at times gameplay, bog down what could've been greater.

By 2014 when Advanced Warfare came out, the end of the world / global scale conflict scenario had been played out in COD stories, luckily the futuristic setting and anti corporate themes, do improve the tired trope with some refreshing adjustments, but not enough to free COD from it's cycle of repetition.

Advance Warfare had a lot to prove, coming hot off the back of 2013's Ghosts, which left the majority of fans disappointed for the first time since their golden era of Modern Warfare 1 - Black Ops 2, due to Ghost's regression in design and lack of innovation.
AW would take the criticism from Ghost's (the poor character motivations, lack luster level design / system mechanics, and weird story pacing) and would attempt to flip the audiences opinion back in Call of Duty's favor.

I'd argue most of these improvements are noticed in comparison to Ghosts, yet like most COD campaigns, Advanced Warfare is still filled with many contrived plot points, weak world building, and over hyped spectacle. Just because it's better than Ghosts doesn't mean much to me.

Maybe if you have never played a COD campaign this game would be more interesting and less disappointing, but even then AW wouldn't be the first one I recommend.
AND IF YOU HAVE played a few of the campaigns, then I'd argue that even with this games unique offerings, it's not going to feel that different.
You are still playing through a simple and easy action movie that rolls on the most linear of cyclical wheels. Clear a few room of baddies, queue cutscene, go to new location, repeat.

The scripting of AI and sequences are just as familiar as ever and the new equipment they add just feels like it makes the game even more casual. The smart / threat grenades put the game on auto pilot.
The explosive cycle feature is nice does open up more gameplay scenarios, but it also makes everything always feel the same, your loadout never changes.

The only exception is the exo double jump which theoretically should vastly change the player freedom and widen the level design, yet this is still a very restrictive COD game we are playing, of course you CAN'T go there.
The game even adds a grapple hook, yet only supports it in maybe 10 unique locations where it would even be useful. To clarify I don't mean 10 levels, I mean 10 or so ledges / objects in the entire game where you can use the grapple hook. To make it not so obvious they only have it even be an option in maybe 3 levels out of 15.

I could talk more about the story or weapons but honestly this campaign doesn't deserve that deep of a dive.

I still need to put more time into zombies because that interests me the most, but this is probably the most mid COD has ever been. It isn't straight up bad, but it also isn't that fun.

PS. the Low detail model pop in is horrible in this game

Marvel level dialogue is all this game consists of. Sarcasm, irony, and the rule of cool is all they understand in the writers room. Not a spec of introspective story telling.
80% of the game is playing thru the irrelevant origin stories of the main cast, which aren't interesting in anyways other than being decent set pieces for levels (ex: Australia, Stalingrad, etc.)
The other 20% consists of the main cast not accomplishing anything other than surviving with their lives still in tact.
Hitler kills himself and the Allies are winning against the Axis whether or not our characters exist. If every main character died, nothing would change in the larger picture of the war, other than how at the very end of the campaign our crew discovers ...wait for it... OOOO secret nazi zombie documents, then the campaign ends abruptly.
Stop tying the campaigns to zombies, also stop making zombies if it's gunna keep sucking. They basically just made a worse version of outbreak from Cold War.
Call of Duty is in a horrible space and they should just stop making them in general, the ratio of good to bad story telling and innovative gameplay is very negative.
