Coming weapon with nade launcher...idea

[Matasar]

Im installing 3ds max again, will take a while to remember everything about skinning and stuff, but i have time to learn.

My idea was an sub or assaultgun with nade launcher attached.

So it fires as usual but when you choose nade it will tilt the gun and fire a nade instead.

So its kinda 2 weapon in one..and it should work right ?
As a made a nade thrower ones and it worked ok with some sound added.

Dont know what gun to make or if i make one from brain only..
Any ideas ?

Game needs some new mods =)
