Mirelurk (Fallout 3)

The Mirelurks are a species of bipedal, mutant crabs from the Capital Wasteland area. Most Mirelurks are surrounded by a thick armor/shell which is difficult to penetrate. However, their face is vulnerable and is the best area to attack. Melee Weapons are basically useless unless you use a very powerful weapon like the Sledgehammer, Ripper or the Shishkebab. Most all Mirelurks attack by barreling toward the player at full-speed, which can make quick work of unprepared adventurers. It is preferable to keep Mirelurks at a great distance, when possible. The Dart Gun will do decent damage over time, and can help prevent Mirelurks from lunging at you.

Mirelurk meat is highly nutritious and grants some of the highest HP replenishments of all the food in the game. Softshell mirelurk meat is even more so. However, both still are slightly radioactive, but no more than typical food.

Appearances
Mirelurks appear only in Fallout 3

Types of Mirelurks
Mirelurks: The Most Common type of Mirelurk. They have a whitish-grey shell, are about a head shorter than a typical human, and walk slightly slower than a human. Mirelurks can be found in most low-level outdoor and indoor water sources. Be cautious of Mirelurk nests that are in or around water sources; walking too close to them will cause all the Mirelurks in the area to pursue and attack you. The head of a Mirelurk is usually too small to be aimed at when not using VATS, so weapons with a high-rate often work well. When using VATS, single-shot weapons like the Scoped .44 Magnum, Hunting Rifle, and Sniper Rifle work well. Drops standard Mirelurk Meat.

Mirelurk Hunters: A much larger, redish-brown colored version of the Mirelurk. In additional to their two main arms, Hunters also have 2 pairs of small, vestigial crab limbs growing out of their chest. Mirelurk Hunters inhabit the Northern Wastes and several sewers and caves near the Metropolitan area of the Capital. Hunters are very violent and are more difficult to kill due to their increased strength and health.

Mirelurk Kings: Mirelurk Kings are different than other Mirelurk variants, mainly because they do not resemble their crab-like cousins, but appear more like mermen. They are fully humanoid, and do not have a heavily armored carapace, making them easy to distinguish from standard Mirelurks. Mirelurk Kings lack the Mirelurks' armored shell, but to compensate they have extremely high health (almost on par with a Deathclaw). They also have a sonic projectile attack that disregards Damage Resistance. Kings are found few and far between in the Capital Wasteland, outside, but more so in caves and sewers, and do not present any other special loot or items over Mirelurk Hunters, except for Soft Shell Mirelurk Meat, which is one of the best foods in the game. Of note, they infest the Reactor area of Vault 92. They only appear when the player is at very high levels.

NukaLurks: A glowing blue Mirelurk that is only found in the Nuka-Cola Factory, almost certainly due to the isotope used for Nuka-Cola Quantum. They seem to be bigger and faster than the normal Mirelurks, similar in size to the Mirelurk Hunters. Their meat is notable for a small boost in AP as well as Radiation and Health, to be exact the meat gives off 4 Rads, +10 AP, and +20 HP.

Strategy for Mirelurks
Mirelurks are strong, tough and mean, but thankfully they only have average speed. Mirelurks have VERY tough carapaces, which makes them pretty tough to dispatch once they get close enough. From afar, the best strategy is to use a powerful, precise weapon to target their vulnerable faces. If you can't get the angle to hit the face targeting the legs can be effective especially in conjunction with the Dart Gun or Frag Grenade. Entering Sneak mode, which lowers the player's height, can improve the chances of hitting the Mirelurk's downturned face both in VATS and when firing manually. The Concentrated Fire perk can also make hitting the face very easy at the end of a series of VATS shots, especially with a weapon that uses few action points such as the Laser Pistol or Laser Rifle. Up close, the Combat Shotgun is recommended to dispatch them, as it does enough damage spread in a wide area to penetrate their armor. The Railway Rifle and the flamethrower also work well against them. It is NOT recommended to get close to them, as they are very fierce attackers.

Players specializing in Unarmed attacks will find the Deathclaw Gauntlet of great value against Mirelurks, as it disregards the otherwise high damage resistance.

Mirelurks can be observed swimming in water. Energyweapons do not harm them under water but conventional bullets do the job. When they are under water VATS will still be able to track and target them.

A useful strategy when a Mirelurk has gotten close in an open are is to strafe in circles around it while your VATS recharges since the Mirelurk will circle around at you from a standing position with it's shoulder turned toward you. Be careful not to get within claw-snapping distance or so far that it can fully turn around and charge you. You can then let it turn fully and take some well-placed VATS shots at the face before it charges.

Mirelurks are often found in groups. Many areas in the game (Vault 92 and the broken front half of Rivet City, for example) are nests of Mirelurks, so they are some of the most dangerous places in the game. This is compounded by the fact they prefer closed, dark places as their nesting grounds, so they can easily overwhelm you in narrow corridors and dead-ends. Beware, Mirelurks can open doors. However they seem to be unable to open doors that are activated by buttons on the walls.

Mirelurk Kings lack the damage-resisting armored carapace of regular Mirelurks, but have very high health to compensate. They can still be brought down with sufficient fire from decent weapons. Headshots are very useful against them.
