I have black ops 2 and havent played the 1st one. But i dont wanna play it if i dont know the story is. Is there like a quick summary for the 1st one so i dont have to play it and understand the 2nd one?
You can play the second game and still understand everything that is going on without playing the first Black Ops, one follows the story of Alex Mason, while Black Ops II follows the story of his son, David Mason.
I personally did not have the first Black Ops, neither did I ever play the campaign mode of it. When I played through the Black Ops 2 campaign nothing was lost on me as all that I needed to know about David's father is told to you through the cut-scenes.
As for a summary you can read one here but it may contain spoilers if you ever choose to play the game later.
Yes you can play Black Ops 2 with out playing Black Ops 1... But I would recommend that you play Black Ops 1 first. You will understand it a lot better.
If you havent played the first black ops its fine but you should because it is a good game. It is very different from the first one.
