From a 1500 hours of play time i could say :-
Gameplay and everything looks nice. Story is a 10/10 but felt short compared to older COD. The game have soo much potential to be one of the best but sadly it can't. The game is filled with campers on every game mode, the game randomly crashes every now and then, the WORST SERVERS ON CALL OF DUTY i have ever experienced. FILLED WITH AIM BOT WALL HACKERS. There is a skilled base matchmaking which will cause good players playing with hackers that never get banned even tho they promised us with a in game kick if they detected a hacker which NEVER HAPPENED . Just imagine getting killed by a camping kid that is using wall hacks and aimbot. Or having to use a vpn just to start your update to download because the update won't work in your country. Or call of duty itself is blocking your entire WiFi company. There is 0 customer support help and they would only provide you with a most "known" questions answers which never been updated !! THE WORST COD I EVER PLAYED
