When you need to defend your outpost from aerial attack, you need an anti-aircraft Ballista. Like this one built by Douglas Hughes, which features not one, but two substantially armed turrets; one sporting rocket launchers, the other, twin machine guns. The cab is very well sculpted with angled panels, and that blue striped detail is a nice touch.
The vehicle is based on the Anvil Ballista from the multiplayer sci-fi game Star Citizen. But Douglas didn’t just build an amazing vehicle, he motorized it (maybe you noticed the cleverly integrated control box on the side) and lit the cab as well.
