Campain: meh... it's okay but feels like they copied and pasted ideas from previous black ops games and is way too short so was quite disappointing, u will love or hate it. Cant say too much without giving any of the story away.
Multi player: horrible... its terrible, all the guns suck everyone camps and the skill/ tactic anyone uses is drop shot... so basically like the rest of the cod games, however, the snipers seem to work so if u cant beat the camping hard scoping snipers... join them, none the less I wanted to try out the new guns but looks like its snipers or nothing.
Zombies: haven't played much but seems okay looks like they copied ideas off other games and added it to theirs... I dont like any of the new things they added but others do, guess I'll just load up black ops 2 if I wanna enjoy zombies.
I mainly bought this for campain and online which both disappointed me, warzone is modern warfare and u get NOTHING extra for having cold war which was another disappointment... legit no real reason for buying this game... want good camping? Plsy every other cod game, want good zombies? Play anything before bo3, want good multiplayer? Try another game franchise... sorry to disappoint but theres nothing new or great that u cant get from moderen warfare both games are linked so just stick with what u got, ur gonna buy this game anyway but u will be disappointed just so ur warned .
