Friend of mine ran an AvPvUSCM Space Hulk campaign a while back (very cool jungle board btw), for which I had the privilege of painting up some of Copplestone's (AFAIK) very-similar-but-definitely-not-predators.
Great fun to paint actually (tried out some NMM on the plate armour, to mixed results - not very NMM, but looks ok imho). Bases all scraps from the bits box and generous amounts of green stuff.
Shame I had to give them back :S
