This game is great. The customization is super in-depth, the graphics almost look live-action at some points, and the campaign is amazing. I'm not even that big of a CoD fan, I've only played Black Ops 4, but I think this is one of the few times I've actually been hyped for a game.
Though, me being a PS4 player doesn't really help. The graphics, while great, take very long periods to fully load. The UI isn't very clear with what's happening; to my knowledge, there isn't even a health indicator. The main menu is also very buggy, sometimes certain things completely refuse to load. In both matches and just in the menu, music completely cuts out along with a few other effects. I expect these to be fixed in a patch as the game just came out, but still, these issues definitely keep me from giving this five stars.
The gameplay, like any other CoD game, is fun and fast-paced. The controls might take some getting used to, but you should be able to learn then before long.
I don't want to spoil it, but the campaign is fantastic. It's not like a room-clearing simulator, you actually have to be stealthy in some parts (which I learned the hard way).
I think that wraps up this review. Overall, this is a great game that's limited by a few flaws. So I'd really, really recommend it!
