Render Unto Caesar Render Unto Caesar is a in " " . Detailed walkthrough . Upon arriving at Caesar ' s camp the player will have their weapons removed ( with the option to keep holdout weapons ) . All weapons will be returned upon leaving the camp . With a Speech of 35 , the player can ask what items are banned , and keep aid / chems , saying they suffer a heart problem . Travel up the hill and enter through the gate to the inner area of the Fort . Here one will find the Legion arena and , most notably , Caesar ' s tent . Enter Caesar ' s tent and talk to him . Caesar will tell the Courier that he has heard a lot about them and will talk about what they have done depending on the Courier ' s past decisions , he will then tell the Courier that there is a vault underneath the camp with the markings of the Lucky 38 Casino . He asks the player to enter the vault and destroy it . He then returns the platinum chip . If Benny is alive , Caesar will inform the player they will get to choose his manner of death . At this point , the player can speak to Benny and decide what they want to do . If the player releases Benny , the Legion becomes hostile towards the player and the quest cannot be completed . Leave the tent and head down to the training grounds . The vault is located within a concrete bunker behind Caesar ' s tent . Upon entering , a Legionary will return all of one ' s confiscated items . Putting the platinum Chip in the computer will provide subterranean access to the irradiated vault . Once the player is inside the vault , one will see a large screen on which Mr . House is displayed . In conversation he will tell the player the purpose of the chip and of ' s objectives before asking the player to finish the job by upgrading the computer ' s security protocol . One can agree to cooperate or defy him . Either way , he will inform the player that he has no control over the vault ' s defenses and that one will have to fight their way to the computer . If House was killed previously , Yes Man will instead be displayed on the screen , though no interactions will be available . Down the stairs one will encounter a hostile , a door , and the rest of the path . Behind the door one will find three computers , two of which are locked . The difficulty of the locked computers are average and hard respectively , once hacked they can be used to disable the vault ' s defenses . The average difficulty computer disables the s , while the hard difficulty computer disables the protectrons . The terminal controlling the sentry bots is broken , and cannot be used . If one is able to hack both , the player ' s path is clear , for now . Head down the hall . If the player ' s Repair skill is 60 , one can open the door on the right and disable the s to prevent them from becoming hostile . In the next room , one will encounter two turrets and two protectrons . The next room is protected by four protectrons . If the player plan on following Caesar ' s orders , destroy the three generators located in this room by shooting them . Once they ' re destroyed , the facility will destabilize and radiation will be released . This option will set off the facility ' s security system , which at this point should only consist of four sentry bots , unless the player chose to disable or destroy them . Before one leaves the bunker , the player ' s weapons will once again be taken away from them , with the exception of their holdout weapons if the player does not wish to be fully disarmed . Go back and talk to Caesar . The player will then receive 500 XP and Legion Fame . Note : No matter what the player has decided , Caesar will not know what the player did inside the vault . He will have felt the vibrations from either the blast or the update and assumed that the player did what he asked . If the player wants to remain friendly to both Mr . House and Caesar , it is best to simply activate the Securitrons using the chip . Part 2 : Mr . House . Caesar orders the player to kill Mr . House . Make your way to the Lucky 38 . If the player blew up Mr House ' s secret bunker , the Securitron s inside the Lucky 38 will be hostile . Use the elevator to go to the penthouse . There are five Securitrons in the main room of the penthouse and they will all be hostile towards the player . In the same area with Mr . House ' s big screen on the left there will be a computer tucked behind the stairs , use the computer to open the antechamber and there will be two more Securitrons waiting for the player . If the player is not already hostile with Mr . House , opening the antechamber will turn the Securitrons against the player . The terminal to the rear - right of the antechamber will allow the player to perform a " Security Override " rendering the Securitrons non - hostile . On the left wall in the antechamber there will be another computer . Use this to access the elevator door next to it and take the elevator down to the control room . Use yet another computer to open Mr . House ' s medical pod . Talking to Mr . House gives three options : Regardless of one ' s choice , the player will receive 500 XP and one ' s objectives will update . Return to Caesar for Legion Fame and 100 XP . Note : If House was killed previously ( such as for installing Yes Man onto the Lucky 38 ' s mainframe ) , this part of the quest will be skipped . Part 3 : Boomers . Caesar wants the player to get the Boomers to use their artillery cannons against the NCR when he attacks Hoover Dam . However , the problem lies in that the cannons blast anyone that gets close to their base ( if the player is already idolized with them then this section can be skipped ) . While heading to their base , will stop the player and offer information on how to get past the shells . One can use a Speech check or pay him , but all it boils down to taking a left turn as soon as one sees the houses and following the house line until one reaches the end Make a beeline for the fence , and once one is close enough , enter the gate . Talk to the Boomers and follow directions until one completes the Boomer questline ( see the Volare ! article for more details ) and have support from the tribe . After all this return to Caesar and let him know that the Boomers are on his side . There is also the option to kill the leaders of the Boomers ( Pearl , Loyal and Jack ) which will complete this part of the quest as well . Part 4 : White Glove Society . The player must bring Caesar ' s offer of allegiance to the White Glove Society . After learning about the society by talking to and Mortimer , one can either tell Caesar they do not want his alliance ( which ends this part of the quest ) or go to Mortimer after talking to Marjorie and help revert the society to cannibalism ( see Beyond the Beef ) . Once the mission has been completed by either reverting them to cannibals or not , return to Caesar . Once the player reports to Caesar , NCR will become permanently hostile . Since NCR controls many places , it will result in loss of quests , merchants , and repairmen . One should prepare oneself before reporting to Caesar . Part 5 : Brotherhood of Steel . Caesar orders the player to go to the Hidden Valley bunker and enter to destroy the Brotherhood of Steel in the area . If one has not interacted with the Brotherhood , the player must go through an orientation by convincing a Ranger in an adjacent bunker to leave ( which can be avoided if Veronica is in the player ' s party ) . Due to the last quest causing Don ' t Tread on the Bear ! to fail and the NCR to name the player a terrorist , the Ranger will not talk to the player and will be hostile , the player will have no further option than killing him . The Brotherhood will confiscate the player ' s weapons , so it is recommended to carry some holdout weapons before entering . From here , one can decide to destroy the bunker entirely or just kill all the Brotherhood of Steel in and around the bunker . To destroy the bunker , the player will need 100 Science to destruct the bunker from the terminal . If one does not have 100 science , one will need to pickpocket the key - cards from Edgar Hardin , Lars Taggart and Nolan McNamara . Once the player has all the keycards , use the terminal next to the Self - Destruct terminal and generate the self - destruct password , go to the Self - Destruct terminal and begin bunker self - destruct sequence . There is not an option to let them live . Once completed , return to Caesar . Part 6 : Caesar ' s Illness . Caesar will now explain that he suffers from painful headaches , caused by a tumor in his brain , and tells the player he needs them to find a cure . One can either choose to find the cure , attempt surgery themself ( which may or may not kill him depending on the player ' s Medicine skill level or Luck ) , or get help from Arcade Gannon to cure Caesar . Be warned ; what happens in this quest will greatly affect the ending of the game . Part 7 : President Kimball ' s Assassination . After completing the previous quest , the player will learn that the NCR president is making a speech at Hoover Dam . The player is ordered to meet with Cato Hostilius to plan the assassination . One must now complete the quest Arizona Killer . Failing Arizona Killer will still allow one to complete Render Unto Caesar . Part 8 : Legate ' s Camp . Report to Legate Lanius , where the player will be teleported to the Legate ' s camp automatically . The second battle for Hoover Dam will begin . Behind the scenes . The name of this quest refers to a Gospel story in which Jesus is asked whether or not the Jews should have to pay taxes to their Roman rulers . Jesus responds by asking whose image is on the denarius . His challenger replies " Caesar ' s " , thus admitting that the Jews are , after all , using Roman money . Jesus then instructs the crowd to " render unto Caesar what is Caesar ' s and unto God what is God ' s . "
