A few months ago I finished painting up eight Spindle Drones, found in Games Workshop's Blackstone Fortress game. These metallic-organic arachnids help defend Blackstone Fortress from intruders. I primed these robotic war machines in metallic silver, then washed them with a purple Army Painter wash. I finished up their bases simply, with some crackle media and flock.
I may have a few uses for them - they could be used for 15mm "tri-pod" aliens (a la War of the Worlds) in a superhero game, for One Page Rules: Grimdark Firefight as proxies for Snipers (Rebel Guerrillas faction), or for an additional small unit add-on in a game of Warhammer 40,000.
