From the website:
Deployed onto the battlefield as elite shock troops or the bodyguards of their magos overseers, Mechanicum Scyllax Guardian-automata have been adapted with a wide variety of mechadendrites and servo-arms for dissecting living matter with murderous speed. With an armoured carapace as durable as Legiones Astartes battle plate and powered by a rad furnace which can vent debilitating radiation at will, the Scyllax Guardian-automata are a force to be truly feared on the battlefield.
The Mechanicum Scyllax Guardian-automata Covenant consists of four Scyllax Guardian-automata, each armed with a Scyllax bolter and various interchangeable claws and mechadendrites forming a mechadendrite combat array.
This is a complete multi-part resin kit. It is available to pre-order now for despatch from Friday 27th March.
