Managed to get my hands on an early prototype of the Berserker and Toxic Abomination and couldn't wait to paint them:
Nah, just kidding :-).
Found these two pre-painted miniatures in my LGS for next to nothing (1.25$ total) and decided that they would 1) be great fun to (re-)paint and 2) work well as a Toxic and Berserker Abomination, respectively.
They were originally produced by Wizards of the coast for some game I've never heard about but the sculpt quality is excellent, and especially the Zombie Enforcer Nazi guy was great fun to paint. His game-plate even had a great motto, which I think I'll adopt for this page: "When the dead start walking, the living run" :-).
The other 'Mr. Doomsball' is just mental - apparently someones forcefed him a naval mine.
Here are some before the repaint and after (but without the blood) pictures, with a Zombicide runner for size comparison.
All the best,
