Troublemaker Games has a new 6mm Superheavy Tank available over in their webshop. They’ve named it the Beast.
From the release:
Beast Class Transport
Skinnerz forces use modular super-heavy vehicles known as “beasts” in a variety of configurations. Some individual examples may be lightly armed and optimised for transport duties, whilst others may be festooned with super-heavy weaponry.
This set contains 2x metal Beast Class Super-Heavy Transports (each 6.1cm in length), plus Laser Cannon & Macro-Howitzer modular weaponry choices.
