The Pumpkin Action Shotgun was created for a Halloween themed Tower Defense FPS.
The idea is a fusion of technology and life (specifically pumpkin vines);
and the gun itslef shoots pumpkin seeds pneumatically.
The Seed Chamber can house 20 seeds which are shot one-by-one or all at once.
The small barrel on the top is for medium-range, high-accuracy single shots and
each shot is primed by actuating the pump located underneath the barrels
(similar to an air-powered BB gun).
The large barrel is for low-range, high-spread burst shots, unloading the entire remainder
of the seed chamber at once in a devestating blast using the compressed air capsules
(giving you 3 burst shots total before having to reload new capsules at home base).
