First I undercoated them in Chaos Black then painted them with a 50/50 mix of Tin Bitz and Brazen Brass all over. After that I painted the skin in Snot Green, the clothes in Bestial Brown, the boots in Chaos Black, the helmets, spikes and bits of the guns in Boltgun Metal and finally a thin coat of Blood Red for the jet packs making sure not to paint over the detailed peices in red.
