First Person Puncher(Unfinished)

Right now I'm working on a first person puncher/ Shooter. The mechanic would be to punch the walls or throw or shoot to use as way to gain height. Im currently having someone making the 3d arms, while im boxing out the level design when i can.

This image shows how i made the punching and shooting. I need to get a better screenshot. But the gist of it is that when you click you punch but when you hold you would ready the gun.

The main character(I might change the design later on.)
