I got to see the minis when I was at the CMON offices while I was down in Atlanta the other day. They are pretty awesome-looking. I really liked the walkers.
From the campaign:
A new miniatures RTS inspired boardgame. Walking tanks, crazy artillery and cool characters battle in the trenches!
Rivet Wars is a miniatures boardgame that springs forth from the warped imagination of Ted Terranova - set on a world that never quite left World War I but with crazy technology like walking tanks, diesel powered armor, unicycled vehicles and armor plated cavalry!
Don't let the cute visuals fool you, it's a world full of angst, war-torn camaraderie and dark humor.
