Crazy, Crazy, Crazy

 is a quest in Fallout: New Vegas.

Quick walkthrough
Find Neil at Neil's Shack and he will give you a mission. You will continue your way up the hill and exterminate the Super Mutant Masters and Nightkin. Once you arrive at the broadcast building, go out the back door and pick up the key under the stairs. At this point you have two choices; kill Tabitha or repair Rhonda, the custom Mr.Handy which can be found in the storage building.

Detailed walkthrough
As you appproach the Neil's Shack A super mutant named Neil approaches you and automatically starts a dialogue.

He will inform you that an another Super-Mutant named Tabitha has taken over Black Mountain. One of her (see the section Extra Details for female gender of Super Mutants) rules is that no Human is welcome to the area and any that approach should be shot on sight.

At this point you will automatically obtain the quest Crazy, Crazy, Crazy which requires you to enter Tabitha's stronghold and eliminate her chaos.

He will also let you know that the area is patroled from Super-Mutants at the daytime while at night cloaked Nightkin patrol the roads.

With a Speech-Check of 50 you can convince Neil to assist you in the killing of Tabitha.

If the Speech-Check is successful, Neil will reply if you're able to reach the village at the north of the mountain he will consider you worthy in his eyes and he will decide from there if you have a good enough chance of success against Tabitha. ( This information is irrelevant since there's not factor included,neither temporary companion, only dialogue options )

From Neil's Shack you'll have to make your way up at the road that leads to the mountain, by fighting against 3 Patrols of Super-Mutants. On your way up you will find the body of an NCR Trooper. If you pay close attention you will see Bear-Traps exactly at legs of the corpse and all the way up to that Hill. Be careful to avoid Bear-Traps and falling rocks if you choose to take this path.

If you choose to avoid this short-cut and take the normal path, the 3rd Patrol of Super-Mutants will include also 1 Nightkin.

Once you reach the summit you actually have 2 options here.
 * You can either talk to Neil and he will help you by misleading the guards at the entrance of the main buildings. This requires you and your companions to move past the guards by stealth since you choose to avoid fighting with them.

Extra Info : When Neil returns from giving false information about "an intruder in the entrance of the Black Mountain" he will start walking back towards his previous location BUT he will not be alone: a number of cloaked Nightkins will be directly behind him and at his side to check out the entrance of the area. Bugs-Section : Please check the Bugs-Sections of this Quest as you will have to face at least 1 of 4 bugs.


 * The second choice is to use a ham-radio which is located at the destroyed building just across from Neil's Position. You have 3 dialogue options, one of which requires 70 Speech Skill.


 * Saying you are a big fan of the Super-Mutants will send the remaining Super-Mutants in the area towards your location.
 * The second option, which requires a Speech check of 70 points, will actually do the same thing as Neil's assist does: send the remaining Super-Mutants and Nightkins to the entrance of Black-Mountain, leaving Tabitha alone
 * The third option will do nothing and is there only for those who changed their mind.

NOTE: If you continue past Neil, it is possible for a Glitch to occur where Neil will not be able to join you regardless of the speech options, always replying "OK. But make it quick."

Once you cleared the whole area from the top of Black Mountain you'll see a building at the left side of the area, which is a storage shed and inside the storare shed you can find Tabitha's robot named Rhonda. GOOD KARMA CHOICE : If you decide to repair Rhonda, which requires a Science Skill of 60 points, you will "activate" the good ending of this Quest , which is ... the moment you decide to leave from the warehouse, Tabitha will spawn outside of the storage-shed and will be happy to see her Robot repaired and fully functional again and she will decide NOT to attack you ( as she's remains friendly ) and you will instantly finish the Quest , and receiving Good Karma as well.

The Second choice to finish this Quest, is to enter the room where Tabitha is inside ,and just kill her. NO KARMA PENALNTY To do so, you need first to enter the room which is located at your map or at your compass. If you have Science Skill of Easy difficulty ( 25 points ) you need to hack Tabitha's Personal computer ( don't search for a named-terminal, it doesn't have any special name, just simple Terminal ). The last entry in this terminal says that Tabitha herself hiding a second-key of her personal room ( the one you need to go and kill her ) below of the stairs leading to her room.

Bugs
Neil the super mutant will tell you to meet him at the top of the hill. He will be located to your left right after you pass the crater (radiation warning). Talk to him when you see him and don't go running ahead. If you go past him and start killing the Nightkin, he will not help you complete the mission, he will be stuck in the same conversation. If this happens to you, you can still complete the quest. (confirmed Xbox 360)

In some situations, Neil won't spawn at all. Confirmed on PC.
