Whole body: Swampsmasher.
Gatling: Chap Mei vehicle
Claymores: Marauder's gunrunner
I made my first vehicle in 2009 (today I'm making one transformer) and it was for the Dark Snake Gang. My first group (actually my first customs).I made it using a knackered Swampsmasher and, well, this was the result.
The name comes from the Gorgonopsians, a suborder of therapsid synapsids ("mammal-like reptiles"). They were among the largest carnivores of the late Permian.
Have mercy dudes!!!
