Campaign missions are very short and lack of actions. The game feels like developed by the game of "checking the box", they have all the parts of a good game but every single part is just bland. The story writing doesn't make much sense, writers want to put you back in the 80s, but they themselves never lived in the 80s as an adult.
Multiplayer is just a hot garbage, on the same level as some free to play title. Guns feel like BB guns compare to the 2019 MW, time to kill is very long but time to die depend on the servers' mood today, one shoot from an AK might kill you from your perspective. When you are tired of the BS it gives you and go to try the hard core mode, but you'll find out it is an after thought (even less work put into compare to 2019 MW), no weapon balance at all.
Graphic is an abomination, lighting came straight out of the BO2 PS3 version, people are like monkeys in the game going up and down with the speed of sound. There are just so many problem that it's impassible to list all of them, it's just a hot industrial garbage.
