Plasmablast Games have released their 6mm Super-Heavy tank miniatures.
From their announcement:
The long-in-the-waiting Super-Heavy tanks by Plasmablast Games are now available. These are two miniatures, one for each of the available “Progenitors” and “Orbital Combine” factions.
The tanks are really big, and carry around an impressive arsenal of weaponry. Following their factions traditions the Tigerclaw (Progenitors) is a tracked monster vehicle (8 tracks.) while the Valgaross (Orbital Combine) is a hovering fortress of a grav-tank. We hope you’ll like them.
