DOOM - Shotgun

My take on the DOOM shotgun. Yeah, I made a regular pump action shotgun a while before, and could have just used that whenever i get around to making Doomguy and scenes and stuff, but I wanted different. Special, even. I got most of it basically done fairly quickly but I kept coming back to the magazine and loading/ejection gate and redesigning it and realizing it wasn't fitting in the space right, etc. overthinking it. Or underthinking it, depending on how you... think.... bah... Idea is it has 3 stacks of 5 in the tube, and every time you pump it, the spindle inside to the gate, slides it into the gate/lifter, and putting the spindle out of alignment and the breech back home on the return side ; whilst also unlocking the breech, extracting the spent shell onto the gate/lifter, spinning *that* around and dropping the shell out of the bottom; all at the same time. Stupidly complex idea, I know.
