Feral ghoul reaver

The  is a type of feral ghoul which appears in the Fallout 3 add-ons Broken Steel and Point Lookout.

The Reaver wears what appears to be the remains of Metal Armor and has significantly more HP than any other form of feral ghoul. It is also set apart from other feral ghouls by its unique ability to throw a grenade-like explosive called "Radioactive Gore", improved speed, and a special effect that emits from its body similar to the Glowing One's radiation pulse.

Characteristics
Feral Ghoul Reavers are really tough enemies, more than twice as durable as Sentry Bots or Deathclaws. The Reavers are extremely quick, and their lunge attack can send the player sliding back some distance with every strike. Their blows, like a Deathclaw's, tend to pack quite a punch, and even high level players are prone to being easily crippled/quickly killed in short order if not careful. As with all fast melee enemies, the dart gun is highly useful in dealing with Reavers. Their radioactive gore easily cripples limbs and is almost always thrown with deadly accuracy. Reavers seem to be highly perceptive as they (unlike Deathclaws) can even detect High Level players in Sneak Mode wearing the Chinese Stealth Armor. The Ghoul Mask is very helpful as they will not attack you if you are wearing it. Similar to Glowing Ones, they emit radiation in large quantities.

Locations
Multiple Reavers can be found during "Who Dares Wins" in the Presidential Metro and in various places around the Capital Wasteland if the player character is of high enough level.

They can also be found in Point Lookout, most prominently at Turtledove Detention Camp, Jet Crash Site and Ark & Dove Resting Grounds.

Feral Ghoul Reavers can appear in Fallout 3 prior to the main quest being completed if the Broken Steel add-on is loaded. Franklin Metro Utility, in particular, will be filled with them at high levels. They can also be found in Taft Tunnels during the Waters of Life quest if the Lone Wanderer is of a high enough level.

They can also be found in Mothership Zeta, in the Cryo Lab, in a room with an alien turret, several aliens, and many cryo pods that contain ghouls and raiders. Some of the ghouls can be Reavers.

Sometimes they can be found in the Museum of History in the same room as Lincoln's Repeater.

Bugs

 * Feral Ghoul Reavers may become invincible for a short period of time. While they can be successfully targeted in V.A.T.S, all shots fired will miss. If this happens, shoot for the legs, or make use of grenades.
 * If a Feral Ghoul Reaver is killed while invincible, their limbs may be stuck in mid-air. Such as when a body clips in a wall, but instead there is nothing there.
 * It is possible to get a split-second appearing message that tells you that Radioactive Gore can be picked up. The message is the same one as for objects shot out of the Rock-It Launcher.
 * Sometimes when the Feral Ghoul Reavers throw radioactive gore, it won't explode, and will keep throwing it, making them easy to kill.
 * Inside the Presidential Metro, when Reavers die, their bodies behave oddly. Their limbs will fly around rapidly and randomly to a point where they can cause minor environmental damage.
 * If killed in the metro by the Mysterious Stranger, their bodies could leave the area all together for a short time.
 * It is possible, but extremely rare, for a Reaver to become permanently invincible and the only way to stop this is to leave the area to a place they can't follow.
