Nukalurk

Description
NukaLurks are a type of Mirelurk and are completely identical in shape and size (more so to the Mirelurk Hunter, as they both have the same vestigial limbs on their fronts), but are differently colored - they appear to be dark blue with glowing blue features. It would be ideal to assume that this coloration is due to the combination of the radiation and the isotope used to color Nuka-Cola Quantum. The NukaLurk Meat boosts AP, is more radioactive than regular Mirelurk Meat, and has a larger health boost than regular mirelurk meat. Although, slightly harder to defeat than regular Mirelurks (as with the hunters), the NukaLurk population is very insignificant compared to other creatures and other Mirelurks so they are not a huge problem, also their meat, having bigger advantages than regular Mirelurk Meat, can be sold at a higher price, or consumed for bigger HP and AP boosts.

Appearances
NukaLurks only appear in Fallout 3, and can be found in the Nuka-Cola Plant. A large number of these creatures dwell in the lower production level of the factory, which has been slightly flooded by Nuka-Cola Quantum. They can be found around the ruins of Megaton if you choose to blow up the town

Tips
NukaLurks are most vulnerable on the face. Normally you will have a 30-55% chance of hitting them (in V.A.T.S if using a weapon like the hunting rifle) however, if you go into stealth mode, when they approach you, their face is more revealed, showing an 80% hit ratio. (Not accurate, depends on weapons skill) It is also ideal to use a Frag Mine while a NukaLurk is in pursuit of you.

Conversely, with a high enough sneak skill (60 or above - otherwise Stealth Boys should do the trick), high enough melee (40 or above) and a Shishkebab it is possible to score sneak criticals that will kill with one hit in V.A.T.S
