I’m fine tuning my “Legends of Shadow World” adventures and debating the mechanics of firearms used by some particular nasty Demon Warriors: basically a large caliber gatling gun! Here is what I used:
Gϋthϋraxx Auto Gun
Weighing 22lbs and 42” long, this ornate hand held rotary gun is the preferred weapon of Gϋthϋraxx Shock Troops. The guns are ornate constructions with a bulbous receiver, curved metal stock and a cylindrical clip of grey/black metal.
