i was really excited when i saw that insurgency was goinf to have a story mode, and im sad that is not going to be added, but any chance?

As far as I am aware of, I don't think they'l be adding that.

From what it sounds like, they had an idea and they began to work on it but then canned it so they could focus on multiplayer. There's nothing saying that they won't come back to it and finish it up.
