This is the rest of the wracks I have built. That will mark 20 wracks. 2 of these have special weapons (one with an Ossefactor and the other with a Liquifier Gun). My army is going to have only three 5-man squads of wracks, but I had the additional 5 built so I thought I'd get them painted while I was in the process. It would have been easier than trying to duplicate the process later.
Grotesques. I'll do an update when they get done.
