I know a lot of people would be happy if the NorFor-addon from Arma 2 got ported to Arma 3 :)

Please make this for Arma 3 somebody (is it possible to port it over?). I want this so bad I'm willing to pay for it.
I just talked to quakecry (his project is in the last post), and he has discontinued his own recent project.
