Campaign - Incredible
Spec ops - Terrible, not the spec ops we know and love from previous games
Multiplayer - Unplayable, full of people camping with claymores at every entrance, fast TTK and "safe spaces" creates a frustrating and unenjoyable experience , also developers have stated this game is made the way it is so the bad players can be good which ruins the experience for the people that are good at the game and know how to play because the lesser skilled players are now able to get easy kills
Overall: IMO this has the best CoD campaign in years however it has the worst multiplayer and worst 3rd mode in CoD history
