I recently received these alien invader figures from Slave2Gaming, which is an Australian outfit. Their service was excellent, by the way. I had a limited amount of painting time this weekend, so I was looking for something I could knock out quickly.
I primed them black and then sprayed them silver. Then I applied a Citadel Nuln Oil wash. I still have no idea what the heck a Nuln is or why it needs to be oiled, but is a pretty good black wash.
From many of my earlier blob posts you can see that I typically avoid the temptation to make all aliens green, but these guys were just crying to have green skin. Though they had nice big eyes that would allow easy painting of pupils, I decided that the figures looked much more alien without them.
I have enough of these to make a full squad for Combat Patrol™ or GASLIGHT plus a heavy weapon team, and an overall leader. I suspect that the overlords of whatever planet they came from feel that that is a large enough invasion force to take over Hoboken, Fitchburg, or Cucamonga.
