The House Always Wins I

 is a 7 part quest in Fallout: New Vegas.

Quick walkthrough
Mr. House tasks you to retrive the Platinum chip from Benny and either use it at The Fort to upgrade the Securitrons, or bring it back to the Lucky 38 so that Mr. House can upgrade them. You will then have to eliminate, take control of, or gain the trust of different factions so that Mr. House's plan will work. You may kill Benny along with House to allow you and Yes Man to take over the plan.

Part One and Two
You must retrieve the Platinum chip from Benny and bring it back to Mr. House. The easiest way to do this is by telling Benny's number two(Swank at the front desk) about his planned rebellion-3 speech checks will needed to be passed to get full exp. from swank, last one being 45-, then going up to Benny's suite, exploring it, informing the number two of the plan, and then going back up to the suite, murdering Benny, and taking the Chip from him. Also, you can convince Benny to remove his guards and meet you in the suite. Go to the safe, pick the average lock, and take Benny out with the weapons inside.

After talking to Swank and recieving your weapons back, killing Benny should reap a positive Karma bonus and no retaliation from the remaining gamblers and bodyguards in Vegas. Doing so also completes the quest Ring-A-Ding-Ding.

If you allow Benny to lure you into the Presidential Suite at the Tops, Benny will flee. You can convince Benny to allow you to team up with him which he will then pay you some caps and flee the room, soon after his guards come in to attack you. You will find that he has been captured by Caesar and Caesar now has the chip. There are several ways you can retrieve the chip from Caesar:


 * 1) Start the quest Render Unto Caesar -- a loyalty quest -- via Vulpes Inculta. He can be found in Nipton, though he may find you first on The Strip.  He will instruct you to go to Cottonwood Cove and then take a ferry from there to The Fort. You will then be instructed to go and talk to Caesar and he will start a quest to destroy the bunker under The Fort. He will give you the chip so that you are able to access the bunker
 * 2) You can kill Caesar after receiving the Platinum chip, or retrieve it from somewhere else within The Fort.

You can now either return to Mr. House, or install the chip yourself in the bunker.

If you killed Vulpes, you can still do the quest. First, take the chip from Benny by whichever means necessary; then get it back to Mr. House. Caesar sends a messenger to you when you exit The Lucky 38, who tells you that Caesar pardons you and grants you his mark and safe passage on your road to Cottonwood Cove. Once you get to The Fort, access the bunker as instructed.

Part Three
You must make your way to Nellis Airforce Base and befriend the Boomers. Getting access to Nellis AFB is the hardest part, as you must dodge numerous artillery shells, which do a substantial amount of damage. You will then be allowed to enter Nellis AFB and you must complete quests to earn fame from the Boomers. Once you have earned the status of Accepted, this portion of the quest will be complete.

Part Four
Mr. House asks you to find out why the Omertas have been so silent lately. Keep in mind that if you complete the Quest The House Always Wins: IV You will fail both Beware The Wrath Of Ceaser! and Don't Tread on the Bear! quests. This means you will no longer be able to get missions from the NCR or from Caesar’s Legion You first need to go to the Gomorrah Hotel and talk to the receptionist.

Part Five
You must go to Hidden Valley and enter the bunker. If you have not interacted with the Brotherhood of Steel, you must go through an orientation by convincing a Ranger in an adjacent bunker to leave. If you warn the Ranger in any way about the Brotherhood, the Brotherhood will become hostile and enter the bunker to kill you. After you have gained the Brotherhood's trust, you can enter their bunker. Once you have entered the bunker, you need to steal 3 keycards from 3 main personel in order to get the password for the self-destruct sequence. It is suggested that you save before stealing from each character in order to avoid killing for the keycard if they catch you stealing. Go to the terminal adjacent to the self-destruct terminal and obtain the password using the keycards. After obtaining all of the keycards and activating the self-destruct sequence, you will become a villian in the eyes of the Brotherhood. While fighting your way to the exit, kill the guards protecting the Elder and steal the key so that you are able to leave the bunker. If you do not steal the key, you must lockpick a door (Lockpick 100). After leaving the bunker, the bunker will explode and you must return to Mr. House.

Part VI
protect president Kimball from assassination attempt. proceed to Hoover damn where you talk to the Ranger in charge. The game then forces you to wait till the next day. after talking to the ranger again he will explain the plan of the day. the quick way to do this quest is to talk to follow the ranger to the observation deck, then talk too him again saying your ready. a helicopter will land above you, go up the ladder on the side and wait until you see an engineer, after he passes examine the helicopter and you will see that there is a bomb, if you have 50 repair or explosives disarm it, you can also pickpocket that engineer and get a detonator, talk to the ranger again and tell him about the bomb, the president is then rushed to the chopper and quest is complete. ALSO look on the tower behind the presidents platform, you can watch the sniper up there get assassinated, the attempt is in 2 parts, a sniper, if that fails bomb on the chopper. I would disarm the bomb then kill the sniper for best results.

Bugs
Message indicating quest failed, despite not having started, while deep within Vault 11. May have been related to activating Lucky 38 override in H&H Hardware earlier in game while exploring. Possibly related to Still in the Dark Questline or be entirely related to Vault 11.Confirmed on PC

If you are enemies (shunned) with the NCR, when turning in The House Always Wins V, you will automatically fail The House Always Wins VI (I'd say this is better because you skip and go to VII, and completion still gives you an achievement/trophy so you dont have to spend extra time with an extra quest)

After eliminating the Omertas from the equation, when you go back to Mr. House to tell him the Omertas are gone, the only dialog options to come up are the ones telling you to go and deal with the Omertas, and you can not finish the quest.

if NCR does not like you, you will autofail part VI of the house always wins. you still get the achievable for the quest chain you will then be prompted for part VII.
