Radscorpion (Fallout 4)

Radscorpions are arachnids mutated from the Emperor Scorpion found in the Commonwealth in the 23rd century.

Background
Radscorpions are a lot more bug-like than their Capital Wasteland counterparts, meaning they are more bony and not bulky. They also seem to be caked in mud, as now they actually burrow into the ground below the player character.

Radscorpions can be formidable opponents on their own and they can become extremely difficult to defeat in groups due to their high damage resistance and strong attack. Evading them is no easy task either since they will constantly burrow and follow the player. This ability allows them to circumvent obstacles and even appear at the top of buildings if attacked from one.

Appearances
Radscorpions appear in Fallout 4.

Locations
Unlike Fallout 3 Radscorpions are a lot less common, they are mainly found in the Glowing Sea but can on a rare occasion be found elsewhere in the commonwealth

One can be found between the National Guard training yard & Relay Tower 0MC-810. And possibly near the Harbormaster Hotel
