So, for instance, I expect these guys will be fought occasionally, so I've made them into supporting NPCs even though they're basically nameless in terms of plot significance:
Weaponized Ordinary Machine for Building, All-Terrain
High Concept: Digging Bulldozer on Legs
Trouble: Unwieldy
+4 Physique, +3 Shoot (sonic cannons), +2 Notice, +1 Athletics
