Ok so there are fun aspects to the game. For one, the campaign is great. I like the whole choose what you want to say in a situation or cutscene, your choices determine outcomes, and the story.
Zombies is the only reason I bought it and I like the new changes. The healthbars, pick up equipment, trials, pack a punch your gun three times, custom loadouts, and of course the easter egg grind. It felt off at first with the arcade type shooter vibe but I am personally a die hard zombies fan. Also, you can level up your guns through zombies and also get special camos and reticles from the mode. Major upgrade in my opinion
Multiplayer. It's inconsistent with the weapon damage and the time to kill is less than desirable. It feels like either your gun is good or absolutely terrible. The attachment pros and cons are just funky. Why does my forgrip help with melee quickness but not vertical recoil? Or why does my gun stock make me slide faster but not help my aiming stability? Idk what they were trying to do with this. The movement feels like BO1 but that's what they were going for with the arcade feel. Also the game crashes on my at least twice a day. When that happens I just go back to MW. The one plus side to me about the multiplayer is that I love dirty bomb. It's your squad of 4 vs the rest of the lobby. It's like plunder but for radioactive bombs. For an even better reference, if feels like a conquest game of Battlefield.
So overall, the game is ok but I can only play it for maybe an hour before I go back to MW. I mostly play it for the zombies now because I've finished the campaign. I can say with 100% confidence that I will not be grinding it out on its multiplayer or even playing the game that much. I wouldn't recommend it but to each his own.
