No, Call of Duty: Black Ops doesn't continue the story line from Call of Duty: Modern Warfare 2. Those two games are set in entirely different eras.
There are rumors that there will be a modern warfare 3 coming out as the next call of duty. The game will be a prequel to modern warfare 2 as it focuses more on the story of ghost, who died in modern warfare 2
call of duty 4:modern warfare call of duty: world at war call of duty: modern warfare 2 call of duty: black ops call of duty: modern warfare 3
the single player modern warfare is a campaign story, and the multiplayer has different game modes where you compete against other players and level up, but theres no story.
The Modern Warfare 3 story mode starts right off where Modern Warfare 2 ended.
Modern Warfare 3 has not been confirmed but if it continues the story than yes.
no
Its a whole different story
NO
nope
yes you should if you want to follow the story line in the campaign mode
No it is set after. Watching the Intro and the scenes in between the missions should make this clear.
no, there's no solid story, I would just get call of duty 4 AND modern warfare 2 for the whole experience though
