Multiplayer is meh. The maps are terrible, you're forced to go 2 or 3 certain ways infested with campers and snipers, I only like one map. The best of Black Ops 2 maps are not as good as the worst of Black Ops 1 maps. Guns are pretty unbalanced, you will lose to SMGs 80% of the time at almost any range, shotguns are still below par with ridiculously short range. 4/10.
I haven't played zombies much but it seems bad. This disappointed me the most, I wouldn't of bought the game without it. Maps are boring and uninspired. Complete lack of weapons on Town, I was stuck from round 8-11 with no ammo and only starter guns available, haven't played any other maps enough but I'm willing to bet it's the same. I'll stick to Dead Island. 4/10.
Campaign is one of the worst in any FPS I've played. Sets a new limit of linear, ridiculous, unrealistic and very boring FPS elements. Every mission is the same- infiltrate, shoot mindless and boring opponents, move on. Repeat for 4-5 hours, that's the entire campaign. 2/10.
I rated 2/5 because combat training and some multiplayer modes are pretty fun when you just fancy a mindless shooter without any skill needed, but if you're going to buy this, bare in mind that even in 2025 the developers for Call of Duty are still moronic sell outs. Anyone who rates this game 5/5 is simply a huge CoD fan boy, and everyone knows they don't have the brain functionality to realize what a good game is.
