First off I would give this a 2.5 stars if I could.
Multiplayer: there isn't enough maps or guns. Also the guns damage are so inconsistent and everyone just uses the m16, snipers or either of the two AK's. Maps are meh and there's not enough of them. Leveling up is just odd and it too is inconsistent. I'm one of the few who enjoyed 2019's MW and i think it did so much better in multiplayer than this one. I don't hate the game and I play it a lot but it's mechanics need a complete reboot.
