The campaign was an absolute joke, but the multiplayer is honestly the best I think it's been in years. Mainly because the OG MW2 had the best collection of maps the game has seen. But also the matchmaking overall is way better, and map voting solves a lot of issues.
Like, the last game was an absolute abomination because there was no voting or vetoing a map. Alboran Hatchery, Black Gold, and Border Crossing were highly hated/frequently backed out of maps, which means there was always an open lobby with one of those maps. So you pretty much got f***ed into those maps every other game.
My biggest bitch about this game is the way they've nerfed claymores. They're essentially useless now. If I'm playing hardcore and you're not dying from a claymore, what the f*** is the point?
