I already thought about the Pig Iron ferals but arent' they a bit chunky (compared to Hasslefree for instance) ?
I totally forgot the Offensive miniatures : that's it for prisonners as they sell a hairless rioters pack. Awesome idea and I can also use them for modern or zombies games.
The Reaper nova marines aren't so bad with a little conversion, especially the last one.
Many thanks Manatic. I didn't know you were on this forum : I am a big fan of your blog and often browse it for Aliens and zombies miniatures.
