Albino radscorpion

The  is a new type of Radscorpion that is added to Fallout 3 in the Broken Steel add-on.

Characteristics
It is far more resistant to attacks than the Giant Radscorpion, and deals far greater damage. They are the same size as Giant Radscorpions and still drop 4 Radscorpion Poison Glands, but are milky-white in appearance and have red eyes instead of green.

Albino Radscorpions are incredibly powerful, their very powerful melee attacks are at par with an armed Super Mutant Behemoth, and additionally they have very powerful poison. An Albino Radscorpion has about 75% of the health of a Behemoth (in other words, 3 times as much health as a Deathclaw). Additionally, like all Radscorpions, Albino Radscorpions lack a "weak point" that can be targeted for extra damage, in contrast to the Super Mutant Behemoth or Super Mutant Overlord, who can at least be headshot for double damage. However, they are affected by the Entomologist perk.

Albino Radscorpions have the unique ability to regenerate their health, which they do in daylight hours, which is coincidental because albinos are vulnerable to sunlight in real life.

Albino Radscorpions can be found wandering the Wasteland, often near major roads, and will utterly slaughter any roaming NPCs they come across. On Very Hard they can kill the player in three hits and kill most NPCs in one.

Albino Radscorpions also have tendency to appear in front of the Tunnel when doing the Broken Steel mission Death From Above, and usually attack and kill the Brotherhood of Steel Knight standing guard. They can also sometimes be found in front of the Arlington Library, as you fast travel to it and appear in front of the door you can possibly spawn next to one, this is extremely dangerous if you have the difficulty on Very Hard.

Also, these nasty creatures appear far more often when a player is above level 20, as they have a tendency to actually replace Giant Radscorpions, so do not be surprised if you encounter two or more in a single battle! In the random encounter where a Wastelander is fighting Radscorpions, there are instances where 4 of these monsters spawn.

Attacks
Though the Albino Radscorpion appears similar to the Giant Radscorpion, it in fact has much more health and seems to do significantly more damage. When encountered, they use similar tactics as a Giant Radscorpion--i.e., rush their unfortunate victim--and they have a similar weakness: they must be in melee range in order to do any damage. On Very Hard, with no perks, less than 15 DR, and an Endurance of 5 or less, an Albino Scorpion can kill you with one strike, surpassing even a Behemoth or Deathclaw's attack in power.

Since they are melee oriented, it is probably best to have a medium to long ranged weapon, like the Repeater Rifle or the Sniper Rifle, and get a sneak attack on it if possible. Using V.A.T.S. to target the stinger, for it's the most vulnerable part of the scorpion. It's also highly recommended to use a Dart Gun to cripple their legs in combat, this makes running backwards much easier.

Another method for short-range/melee fighters (shotgun/sledgehammer...etc.) would be to place an obstacle between yourself and it (such as a tree as it doesn't move sideways nearly as fast as it moves forward.) and rotate in a circular motion and whittle away its health with attacks on its claws or head and keeping yourself safe to boot.

If you have the Metal Blaster from The Pitt add-on, the Snide Survival Guru perk, Better Criticals and Finesse, killing these monsters is easy, as long as you're running backwards while it's rushing you and there's no obstacle that can stop you.

Because of the pathfinding on the 360 (not sure for other versions) All scorpions can be made harmless by finding a single high point (boulder, truck, shack, destroyed building) And just chip away with whatever weapon you want. The scorpion will be forced to go back to a half idle mode because it can't attack you and it will wander. Be warned, if you jump off your perch it will make a beeline to your position to continue its assault; though a useful tactic if it wanders too far.

This kind of Radscorpion can easily kill a Deathclaw.
