This kind of Rat trap was designed with the anal nuisance in mind
Vermin are not supposed to compete for ownership of a build with serious nuisance, they feel stronger, more like a Leopard or Bear that would wander around with less care than a Rat wanting greater things. Human intelligence makes them better able when the implants cooperate, but they are unable to recognise the International Conflict danger or respond intelligently to warnings. They indulge themselves in a Vermin victory against a Human, who are greater.
The Dungeon is based upon taking a wounded live catch to a Nest.
