Usually when painting I have something on in the background, usually a film, online videos, music, just something to keep things from going quiet. I think this might be a sign I should stop.
So yes, here's an Ork looted Dreadknight. One painted and built like Megas XLR with every weapon in the dreadknight set and two more just to be sure. I did try to make an ork look like Coop but the results were not pretty.
I wonder if this comes close to approaching "nearly 'enuff dakka." That and how the thing has enough ammo for most of those guns, what are the orks teleporting them into the barrels from orbiting ships? Actually that does sound like them.
