The first time I flicked through the Chaos Space Marine codex, The Purge jumped out at as a unit I just had to paint. The green and black colour combination looks great, and reading on, the theme behind the faction is great too. They're Nurgle, but not that disgusting type of Nurgle.
These guys needed their metals done for their backpacks and weapons, the Nurgle banner and their basing. Didn't take too long with the magic of Devlan Mud, and I'm happy with the standard of painting on these guys.
