Heldelance: If your up for it you could play around for implementing the shotgun secondary fire alongside the grenade secondary fire with the FN F2000 for me
that way by the time you have done that (if its possible for a fully working implementation) I could be finished with all the other guns.
The Dragunov would be an awesome addition to STALKER, but I think thats what the SVD mk2 is supposed to be (its a special weapon) I have thought about adding other weapons, but for now I'm balancing all existing stuff before adding anything. My ultimate goal is for STALKER to look as good as originally intended and to have the gameplay it should of had.
