Also got the engine finished. I had ordered some really cool engines from Blood and Skulls Industry, they are awesome looking, but way bigger than I thought. They will be saved for a future project, and I ended up customising an engine from a sentinel.
Desided that the previous shown weapondesign will instead be a Graviton cannon, as I got a new idea that kind of fits better with a Shockwave cannon. That means the first Myrmidon will be armed with a different HtH weapon, one I've been wanting to use ever since I opened the Killercans box - the piston driven powerdrill, such a cool piece. The Glaive will be saved for the next Assault Engine instead.
