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.

Part One and Two
You must retreive 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 about his planned rebellion, 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.

If you allow Benny to lure you into the Presidential Suite at the Tops, Benny will flee, and 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 Caesar's Legions loyalty quest by going to Nipton and talking to Vulpes Inculta. 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.
