Radscorpion (Fallout 3)

Radscorpions are creatures found in the Capital Wasteland in 2277.

Background
Radscorpions are mutated from the North American Emperor scorpion, which were prolific in many pet stores at the time of the Great War. Contrary to many expectations, their venom grew much more potent and deadly when they mutated rather than becoming diluted. Their poison is used in crafting the dart gun. Though considered nocturnal and sensitive to light, radscorpions can be found active during the daytime in the areas they inhabit. Apart from their size, they appear visually identical to regular scorpions, with thick, mottled, dark, blueish gray carapaces.

Biology
Radscorpions are not only powerful, but also have a nasty venomous sting that can kill the player if not treated quickly. Since they are indigenous to desert environments, they do not mind the brightly lit environments and will attack the player in broad daylight as well as at night.

Radscorpions can be seen burrowing into the ground from time to time, much like their pre-War cousins. These burrows are likely where they sleep and take refuge from the harsh external environment, like heat and sandstorms.

Gameplay attributes
Radscorpions will usually attack head-on and then attempt to flank the player. Unlike other creatures, radscorpions lack a "weak point" that can be targeted for extra damage (such as a "head" for a headshot), which makes V.A.T.S. combat and firearms somewhat less effective against them. Radscorpions also take significantly reduced damage from any shots that hit their legs, such that even a critical hit from a high-powered weapon will only do minor damage.

Radscorpions can often send low level players running for the hills, since they can be difficult to get rid of without getting seriously injured or killed.

All radscorpions are affected by the Entomologist perk.

Radscorpion
The most common variety of radscorpion. These venomous predators seem to possess different speeds, some taking their time and others bolting at top speed. Their size ranges from that of a large dog to small livestock.

Giant radscorpion
A much larger radscorpion with an much more potent venom. These terrifying creatures can reach incredible sizes, ranging from livestock to a Corvega. The giant radscorpion is commonly encountered usually in the west and far south of the Capital Wasteland. 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.

Albino radscorpion (Broken Steel)
Albino radscorpions are about the same size as a giant radscorpion, but instead of having a dark bluish-gray appearance, they are pale white with pink joints and eyes. They deal out very high damage while taking very little themselves, while their stingers contain an extremely potent venom. They are exceptionally tough and have significantly more hit points than almost any other creature or non-player character in the game, surpassed only by a super mutant behemoth and General Jingwei. A unique trait about these radscorpions is the fact that they slowly regenerate health when exposed to direct sunlight.

Like regular radscorpions, they have no weak point, but their legs can be crippled to undermine their mobility. Albino radscorpions are affected by the Entomologist perk. You can find an albino radscorpion anywhere giant radscorpions spawn. High level players may actually encounter more albino radscorpions than regular radscorpions. As evidential by their statistics, albino radscorpions are one of the toughest creatures to fight in the wasteland.

Appearances
Radscorpions appear in Fallout 3 and its add-on Broken Steel.
