To start the series of quests , talk to Yes Man after confronting Benny at the Tops casino . Wild Card : Change In Management . Yes Man needs to enter Mr . House ' s computer network . To do so , you must get the platinum chip from Benny , and then kill or disable Mr . House . To disable Mr . House , the Courier must have already entered the Lucky 38 penthouse suite . On the wall to Mr . House ' s right ( Courier ' s left ) , there will be a terminal . Activating the terminal will come up with a single option , that is , to open a hidden wall . The new entrance will lead to the antechamber , which leads to an elevator . The elevator is activated by the terminal next to it , and takes you to Mr . House ' s control room , where an aged Mr . House resides . Activating the control panel to the left of the walkway gives the player a choice to open the chamber keeping Mr . House alive . You may then allow Mr . House to live , but allow Yes Man to enter the system , or kill Mr . House and let Yes Man into the system . After dealing with Mr . House , get Yes Man from the Tops casino , where he will instruct you to follow him to the Lucky 38 . You can then meet him inside the penthouse suite , where he will use the platinum chip to enter Mr . House ' s network . Wild Card : Side Bets . Yes Man needs to know which " tribes " out in the Mojave will help or hinder him . Specifically , Yes Man wants you to meet with and learn about the Brotherhood of Steel , the Omertas , the White Glove Society , the Great Khans , and the Boomers . You must either meet with the groups , learn about their history , and tell Yes Man that they can be ignored , or you must do multiple quests for each " tribe " , putting them into alliance with you and Yes Man . Wild Card : You And What Army ? Mr . House ' s Securitron army is in desperate need of an upgrade . With Yes Man in charge , the Securitrons belong to you , so it would be to your best benefit to upgrade their model . Go to Fortification Hill via the Cottonwood Cove ferry ( note that if you have the Mark of Caesar you will be granted definite entrance to the Fort ) . Follow the path up to the top of the hill . You will be led to a drawbridge , which will take you to the Fort ' s camp . From there , head along the left side of the camp . A weather station will be at the end of the left - most camp . Inside are three Praetorian Guards who will attack you upon entrance ( the one to the right of the entrance might start a quick conversation ) . Staying in alliance with Caesar will cause them to give you your weapons back . Failing the quest Beware the Wrath of Caesar ! will cause them to be hostile ( this can be avoided by starting the quest Render Unto Caesar ) . If the latter is true , they will put up a hard fight , even for skilled and high level players , as they all have ballistic fist s . Insert the platinum chip into the console to the left to open the bunker . Note that there is a small radiation level ( 1 Rad / sec ) . Proceed to the end of the bunker and insert the platinum chip inside of the console at the end of the bunker . Return back to the Lucky 38 to view the newly upgraded Securitrons , as they step up from 9mm rounds and laser shots to missiles and grenade rounds . Notes . Finishing either Side Bets or Change in Management will trigger Beware the Wrath of Caesar ! and Don ' t Tread on the Bear ! , assuming you haven ' t failed one or both already . Finishing both will fail both quests . Both quests can be postponed up until the final mission for either faction . Behind the scenes . The term ' Wild Card ' means either a card that can be anything in Poker , or a person who is generally unpredictable .
