Campaign- Really good. It was very short however, but side missions and multiple endings kind of make up for that. If you were a fan of bo1 and bo2, this campaign is for you
Zombies- the zombies is extremely fun. Even when playing solo, it's a blast. It's a shame there is only one map at the time I am writing this, but it is still very fun.
Multiplayer- when I am playing with friends, the multiplayer is pretty fun. however, when your playing solo hit can get extremely boring. First of all, sbmm needs to not exist. I hate how parts leave after each round because your getting ranked again. Games are unfunny because if you do pretty good one round, your going up against pro players the next round. Also. Split screen never works. Maybe that's just for me, but I am never allowed to do split screen. It says connecting, and then freezes up
OVERALL- this game is still pretty broken and sometimes but I feel like if treyarch really listens to the fans like they have been doing most of the time when it comes to this game, it will be amazing.
