Primarchs. They are a triumph of genetic engineering. They are paragons amongst an already-impressive group (the Space Marines). They are unmatched in combat, with only other Primarchs able to stand against them (unless you've got an army or fleet or two to throw at them). For the Ultramarines (don't you dare call them vanilla!), their Primarch is Roboute Guilliman. He's now available to order from Forge World.
The figure is a multi-part resin kit. It comes with a 40mm gaming base, but also a 60mm scenic diorama base (to really show him off to your friends).
You can order yours now and they will begin shipping out next Friday.
