This started off as an old Battlefortress. I first cut it's rear tracks off then fitted them again but a lot wider then they were before. The extra gun turrets came from a Mega Gargant I had butchered for my Gargant conversion. The paint is an undercoat of Chaos Black then a 50/50 mix of Tin Bitz and Brazen Brass painted all over. After that I dry brushed it with Boltgun Metal until I got the appropriate rusty metal look. The other bits are just Chaos Black and a thin coat of Blood Red.
