The maps are awful, literally spawn in, run over a hill or round a corner and bang dead, also maps feel way too small, feel like they are all meant for FFA and it's a massive drop from modern warfare, tbh my only issue with modern warfare is that it's just massive and i don't want it on my PC otherwise id play that instead.
I've not played the camp yet but zombies is okay, the rounds drag out now and it's a shame but if you make it to around round 25 and don't have the raygun then you're just going be shooting so many bullets just to kill your average zombies so it's doesn't really make sense as personally i don't just like using the raygun all the time but you kind of need too and the megadons are cool at first but just get on your nerves later. also the new PP is just horrible, guns look, well i don't think theres a word for it yet...
I can't find the mental capacity to understand why this game is getting so much praise, honestly i wouldn't even recommend this game to someone with billions of pounds.
