The game is pants
Played on the Series S and the experience in the campaign wasn't a good one, assets just popping in to existence on the desert level and multiple times I had enemies just appearing out of thin air. The movement and the way the guns shoot also just felt off.
Campaign - personally I found it boring, the story is stupid and it was like I was playing the bad bits of other games. I got about halfway through and that was enough for me.
Multiplayer - Again the movement just feels off but you can get it to feel a little better with a little messing in the settings, as for multiplayer it's just more the same. Spawn killing, people glitching out of the map, others firing a handgun faster than an Uzi same old same old.
Zombies - probably the only bit of fun I've had with the game but still it's not as good as the other iterations.
I do think it's time for call of duty to take a break for a couple years, maybe keep the multiplayer ticking over with new maps every six or so months, use the time to fix the multiplayer and think of a proper campaign.
