This is a good FPS game, the story line its a bit dodgy at times but the gameplay is very good in my opinion. I got Xbox live so i play it more or less everyday and if i compare this to MW3, Black ops is way much better. The lighting is not "gloomy" as MW3 and the map is way way better- MW3 got such stupid maps. Lastly campers- in Black ops not many campers and you can "revenge" on them the next time you respawn unlike in MW3. Hopefully Black Ops II as good as this one.
online it is the best call f duty ever in my opinion. very fun as well as the added zombies :) a challenge (probs the best thing treyarch have done)
the story mode is stupidly hard at some points (veteran mode)
u need luck to complete the game. some bits must have taken me about 6583734 attempts to do. lucky i am patient otherwise the xbox would have been out of the window :D
