With all the weapons and such the ship stands at around 49mm long, slightly bigger than an escort, not big enough to be a cruiser. I tried stretching the model a bit to make it about 75mm long, which gives it this amazing battleship look, would make a great cruiser (after a lot of modifications), so that might be in the pipelines as well.
The idea behind these ships is that they're made of scrap, but are constantly morphing, evolving, and assimilating, it's also why I want the Legion turret on the front, it's basically a part the ship incorporated into itself after destroying a Legion cruiser.
Background is slowly starting to sort of flesh itself out. I imagine this Terramorph faction to have carved its own little empire. The Terramorphs have assimilated all mater around them, incorporating it onto their own bodies, ships, etc. But they're running out of new matter and technologies, which is why they've started attacking Legion outposts, assimilating new technologies onto their existing bodies.
It's basically Transformers meets the Borg, meets Orky technology, meets Tetsuo the Iron Man, and a bit of undead in there...
A game could easily be set up, a few Legion cruisers and escorts against a group of these raiders and perhaps some variants.
