Radscorpion (Fallout: New Vegas)

Radscorpions are creatures found in the Mojave Wasteland $$

Gameplay
Common places to find radscorpions are Scorpion Gulch, the scorpion burrow, the scorpion valley near Goodsprings Cemetery and the Yangtze Memorial. The area around Nipton Road reststop and Mesquite Mountains camp site is also inhabited by a large number of radscorpions.

As radscorpions almost always move in groups of two to five. They tend to charge their intended targets directly and will use their powerful claws and poisoned tails for quick and relentless attacks.

Radscorpions take normal damage when shot in the torso, stinger, or claws, and reduced damage when shot in the legs. Unlike other creatures, radscorpions lack a "weak point" that can be targeted for extra damage (they have no "head," for example), which makes V.A.T.S. combat and firearms somewhat less effective against them. Additionally, all radscorpions are armored to some extent, making them even more difficult to kill.

Their claws are less-armored than the rest of the carapace; successfully crippling these will stun the radscorpion. Using the Guns skill, the creatures are vulnerable to armor-piercing weaponry.

Radscorpion
These are the most common variety of radscorpion. These poisonous predators seem to possess different speeds, some taking their time and others bolting at top speed.

Small radscorpion
The smaller and less common variant of radscorpion.

Giant radscorpion
A larger and much more dangerous variant of radscorpion that is faster, as well as rarer than the usual radscorpion. It does a lot more damage and has a higher Damage Threshold.

Radscorpion queen
Only two are found in the Mojave Wasteland, in the scorpion burrow south of the Nipton Road pit stop and just east of Crescent Canyon west and inside the Searchlight fire station.

Behind the scenes
According to Joshua Sawyer, radscorpions received an increased Damage Threshold in Fallout: New Vegas because they look larger and scarier in a 3D engine than they did in the isometric view of Fallout and Fallout 2.

Bugs

 * When viewed from a distance, the radscorpion(s) frequently slide vertically across uneven terrain (interfering with V.A.T.S. aiming). On the PC version, they can also possibly sink into the ground making it near impossible to kill them. If the Courier is unable to kill the sunken radscorpion, it remains as a red tick indicating an enemy on the radar, making it also impossible to leave the area by fast travel.
 * In the case that a radscorpion has fallen underneath the ground and the Courier's companions have weapons, the follower will attempt to attack the enemy until they either run out of ammunition or the radscorpion is killed by a general area of effect weapon, such as a grenade.
