There's subtle murderbots, and there's "subtle" murderbots.
About this creation
The former can kill you in a crowded room without anyone noticing, the latter can kill you and everyone else in the building without too many people in neighboring nations taking an interest. Guess which one this is?
No Space Viking corruption upgrade; Space Vikings hate robots. Something to do with them being "tools of Loki" or something like that. You have to admit, they have a point; whenever you hear of a mad roboticist (or any kind of mad scientist, really) dying, you always think "because of one of his own monsters, I bet."
