Large versions of the North American Emperor scorpion that are found after the Great War.Antidotes have been derived from their venom.
Radscorpions will usually attack head-on and then attempt to flank their prey. 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, meaning that even a Critical Hit from a high-powered weapon will only do minor damage. While close-by or indoor, radscorpions will make a distinct "walking sound" that gives their presence away, though it may happen that a radscorpion stays idle until it notices the target. All radscorpions are affected by the Entomologist perk.
The most common variety of radscorpion. These venomous predators seem to possess varying speeds, some taking their time and others bolting at top speed.
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 slowly regenerate health when exposed to direct sunlight, similar to the effect of the Solar Powered perk.
Targeting their stinger does not affect the ability to collect poison glands, even if the killing shot depicts the stinger being blown off.
It is possible to find a non-hostile giant radscorpion wandering the Wasteland, as part of a random encounter. It will attack raiders, creatures, and any other hostile characters it comes across. Companions, however, are likely to attack it. It may run away if wounded and if the Lone Wanderer goes near it, it will start fighting them.
Usually, one or more giant radscorpions (at high levels, they will most likely encounter albino type) will spawn just outside Regulator HQ, and be attracted to the mooing of the brahmin outside. They usually target the brahmin first, unless they spot the Lone Wanderer.
An Enclave research terminal states that the giant radscorpions are "just exaggerations" made by the operatives.
It is odd that albino radscorpions will slowly heal in sunlight since albinism is usually associated with extreme sensitivity to sunlight.
Radscorpions are physically long creatures and therefore have a wider and slower turn radius. However, albino radscorpions do have a higher movement speed in general.
Radscorpions tend to emit a sharp hissing sound whenever they use both their pincers and their tail as they attack.
Radscorpions walk backward if either charged by the Lone Wanderer or take damage from a significant melee attack, such as from a deathclaw, which makes it easier for Unarmed and Melee oriented characters.
Xbox 360 If the dart gun is used against two 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. [verified]
