That was a quickie - ever since oportunity to work on those apeared it has taken Kuba reasonably small amount of time to create first prototypes.
In fact it went so well I've asked Kuba to charge his Rhino-fu even furter and work on pistol set.
With those done adding a heavy weapon was really straightforward :) .
Displacement guns are available for a couple of weeks and I've just added the pistols. Heavy weapon variant should be released soon.
Again it was pleasure to see how well Rhino3d works for such projects.
