Giant radscorpion

Giant radscorpions are much larger versions of the radscorpion with an even more highly effective stinger.

Giant radscorpions often travel and fight in pairs. It's not uncommon to see one turn from the player and back off, only to be joined by another and charge in again. In fact, they seem to operate in pairs most often, only preferring to attack alone when their partner is dead.

Statistics
Their health is on par with that of a Mister Gutsy robot or super mutant master. Additionally, giant radscorpions lack a "weak point" that can be targeted for extra damage (they have no "head" to headshot), which makes V.A.T.S. combat and firearms somewhat less effective against them. Crippling their legs with mines also makes the fight much easier, as their charge becomes much slower. As with radscorpions the dart gun is not very effective against it, slowing it down less than other creatures when hit by the dart gun. They are affected by the Entomologist perk.

It is wise to note that V.A.T.S. shots on the stinger aim for the third section from the bottom. If this area isn't a selectable target, then V.A.T.S. isn't advised.

Loot

 * Four radscorpion poison glands will be found on a dead giant radscorpion. These have a base value of 30, and should be sold en masse for a lot of caps.

Appearances in Fallout games

 * Radscorpions are encountered in all Fallout games.

Bugs

 * If you use the dart gun against 2 giant radscorpions (shooting a dart at one first and a second dart at the other one), the weakest one will disappear from sight while the other is still engaging.
