Wild Card : Change in Management Wild Card : Change in Management is a in " " . Quick walkthrough . This series of quests leads to one of many . Once you discover Yes Man , he will explain Benny ' s plan to kill Mr . House and take over New Vegas . The player will then be able to choose either to continue with Benny ' s plans or take on this quest , killing Benny . You will have to head towards the Lucky 38 penthouse , locate the chamber in which Mr . House actually resides , and either choose to disable him or kill him . If you choose to kill Mr . House , meet Yes Man at 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 ( named the antechamber ) leading to Mr . House ' s chamber . Unlocking the terminal requires either : After activating the door , an alarm will sound and the securitron s will become hostile . They can easily be defeated with the , or if you have a , you can use it to sneak past them . It is also possible to run past them and head to the next terminal . Behind the hidden door are two more terminals . The terminal on the right in the back allows a " Security Override " to be performed which will stop any remaining securitrons from attacking on sight . The second terminal , on the left near the elevator , is used to unlock the elevator . Activate this to head on to the control room . Once in the control room , there is one final terminal . Activate it 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 result 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 . Alternatively , after you open the chamber , you can attack him . This will result in his death and a strange death animation where the entire isolation chamber will jump to the side and will still continue the quest . 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 . Once you have killed Mr . House , it is time 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 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 Yes Man further will cause you to be unable to work with those factions . After installing him on the Lucky 38 mainframe , he will make the demonstration about the Securitron upgrades at the Lucky 38 basement . 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 . Notes . You can perform this quest simultaneously with For the Republic , Part 2 and Render Unto Caesar , as long as you have not completed both and Wild Card : Change in Management , or if the NCR or the Legion have become hostile to you . You would have the potential to still be on both the NCR and Legion ' s good side .
