But Onslaught has some figures that will definitely stand in for them. Here are their Gashers (not-Hormagaunts), Stalkers (not-Termagants), Prowlers (not-Genestealers), Winged Stalkers (not-Gargoyles), Overseers (not-Tyranid Warriors), and Mantis Beasts (not-Lictors):
I painted the figures white, then washed the figure entirely with Citadel Purple Wash (the older stuff, not the new ones). I then picked out the white areas with a small spotter brush, leaving the purple wash behind in the crevices. As you can see, the deep recesses of the figure make this quite easy to get a decent effect. I then painted the armor plates purple and the claws red. I make use a brighter red at the very tips (I am still thinking about it).
Note that this figure is about 10-12mm, as it is a giant in 6mm scale. But all in all, very detailed, quick and easy to paint, and a fun looking sculpt. To get a sense of scale, here it is beside GW Epic Eldar (new sculpt) and Space Marine (old sculpt) figures:
What has me drooling are the not-Tau:
The not-Crisis Suits:
The not-Dark Eldar:
And the not-Vespids:
They all look very fun to paint!
At $7.50 for 25 figures (of the smaller models) they are certainly more expensive than Baccus 6mm (you would get about three times as many figures for the same price), but I think the quality is better.
So, if you are an GW Epic 6mm fan, head on over to Onslaught Miniatures and check them out!
