I should clarify. I don't want NPCs you have to talk to and get missions from. You're more or less right; if you want that, you should play something else. I'm talking about making Helghan a place with civilians who are caught in the middle of a ground war, who are running for cover while their city and homes are being destroyed. And I think it would be cool if you were under orders not to harm them, and, if you did, instead of starting over from the checkpoint (like you do in this situation in a lot of other shooters) if the civilians in the background began to fight back.
To me, it's a way to make the environments more dynamic and to make the gameplay more involved than simply lighting up targets, hence I'd like to see something like that implemented.
And I have to disagree that wars are fought away from civilians. I don't think you have to look too far back in world history to see examples of wars fought in the middle of massive, populated urban centers.
And I think that the aesthetic of many of the settings in KZ2 are distinctly urban and even a little suburban. It's not too much of a stretch to add the wrinkle of non-combatants to the game.
