Wild Card: Change in Management

 is a quest in Fallout: New Vegas.

Objectives

 * Recover the Platinum Chip from Benny.
 * Kill or disable Mr. House.

Quick walkthrough
This series of quests leads to one of many Fallout: New Vegas endings. Once you discover Yes Man, he will explain Benny's plan for killing Mr. House and taking over Vegas. The player will then be able to choose to continue Benny's plans and taking on this quest. You will have to head towards the Lucky 38 penthouse, locate the chamber in which Mr. House actually resides, and choose to either disable or kill him. After killing Mr. House, meet Yes Man outside The Tops casino and accompany him to Lucky 38.

Detailed walkthrough
After entering the Lucky 38 penthouse, find a terminal on the wall near Mr. House. This terminal will allow you to unlock a hidden door leading to Mr. House's chamber. Unlocking the terminal requires either: After activating the door, an alarm will sound and the securitrons will become hostile that will be easily defeated with the Pulse Gun but you can also just skip them and run to the next terminal. Behind the hidden door lies another terminal, as well as several securitrons which will attack on sight. Activate this to head on to the control room.
 * 75 science
 * A Lucky 38 VIP keycard from the H&H Tools Factory (top floor)
 * A Lucky 38 VIP keycard from Chief Hanlon's desk in his office (inside the main building at Camp Golf).

Once in the control room, there is one final terminal. Activate this terminal to release Mr. House's isolation chamber and expose him to the outside world. You can then talk to him, and he will tell you how your "Vanity Project is doomed to fail". You then can decide his fate by going back to the terminal and choosing to either kill him (also possible via the "Sterilize chamber" option) or leave him helpless, both of which resulting in loss of karma. Note that once the isolation chamber has been opened, regardless of the fate you decide for Mr. House, he will die within a year from exposure to outside contaminants.

To pass the initial terminal you can choose to either pass a Hard difficulty hack or execute an Executive Override and obtain the password to the terminal from either H&H Tools Factory or the hotel in Camp Golf.

If you decide to kill Mr. House, you will receive the note A Tragedy Has Befallen All Mankind, and the quest The House Has Gone Bust! will instantly be started and failed.

The Kill or Disable Mr. House stage is complete once you either kill or disable Mr. House. This can be done before or after you speak to Yes Man the first time.

Once you have killed Mr House to meet Yes Man return to Benny's suite at the Tops - he's in the room beyond his bed. Talk to him and he'll agree to meet you at the Lucky 38.

Sometimes Yes Man disappears after you kill Benny, if you leave Benny's apartment and return later. He can be found standing outside of The Tops Casino. You can tell him to meet you at the Lucky 38 without incurring any faction penalties. Once you meet him in the Penthouse of the Lucky 38, where House's avatar formerly spoke to you the first time, the installation of Yes Man event is triggered. This triggers two quests, Beware the Wrath of Caesar! and Don't Tread on the Bear. This puts you on notice that working with Mr. House further will cause you to be unable to work with those factions.

You can let Yes Man wait for you at the Lucky 38 until you finish most of your other quests with the NCR and Caesar's Legion and are ready to proceed.

Bugs

 * After having Yes Man installed onto the big screen, you may be unable to quit first person sight or to use the "wait" command. This is not permanent as it happened to me and then all of a sudden (many hours later) I was able to go into third person view and use the wait command.  However, I am unaware as to how they were restored.  I can tell you that all I remember doing before realizing they were fixed is giving Sarah Weintraub(Vault 21 gift shop) 30 vault suits and then sleeping with her.  Hope this helps somebody.


 * After disabling House the objective does not check off which prevents Yes Man from meeting you outside Lucky 38. (Double check that you have selected the option to permanently disable House from all systems on the same console used to wake him from the chamber)


 * If Benny escapes to the Fort, the journal entry will be 'Retrieve the Platinum Chip from Benny at the Fort'. The quest marker will point to the raft at Cottonwood Cove. After traveling to the Fort, the marker will disappear and Benny is nowhere to be found.


 * Benny is found in Caesars tent. You have to kill Caesar and his guards.  Get the chip off of Caesar and then talk to Benny. Completing the all other Wildcard quests may prevent these two bugs from happening.


 * After the walkthrough of the upgrading of the securitons finishes and Yes Man tells you to meet him back up top or to feel free to leave you will not be ported back up to him and will not be able to get out of the room.


 * Securitrons may not become hostile or only Jane will


 * After you install Yes Man onto Mr House's big screen, a ripper will misteriously appear in your inventory. Your current item storage weight is unaffected by this for example I had 175 pounds worth of gear and after I got the ripper I STILL had 175 pounds. Removing the ripper REDUCED my overall carry weight to 169..(360 VERSION).


 * Sometimes you do not need to have the Lucky 38 VIP Keycard or a Science skill of 50 to activate the terminal, it will be automatically be unlocked. Verified
 * It is possible to enter the Lucky 38 with your companions, even though the Yes Man will tell you that you have to leave them behind. If you enter the Lucky 38 your companions will be with you until you enter the elevator in the middle of the room, after which they will disappear. It is unknown as to were they go at this time.
