Yes Man

Yes Man is a securitron robot that serves as Benny's assistant in 2281, and is an integral part of Benny's scheme to take control of Vegas. After Benny takes off from the Tops casino, the courier can use Yes Man to go for the Independent Vegas end.

Background
Yes Man was originally a generic securitron robot working for House, like all the other securitrons found on the Strip. He was damaged by a pulse grenade, and was recovered by Benny, who then allowed a member of the Followers of the Apocalypse to examine the securitron, in exchange for reprogramming it.

The reprogramming was extensive, and resulted in Yes Man being designed to do exactly as he is told (although the lack of restrictions on who is doing the ordering would later be Benny's undoing). The plan was to dispose of House, plant Yes Man's A.I. in the Lucky 38 mainframe which would then put him (and by extension, Benny) in control of all the other securitrons on the Strip, and then take the platinum chip to Fortification Hill where he could activate the securitron army, enable the Mark. II OS and use the upgraded securitron army to take control of Hoover Dam and Vegas.

Yes Man is left behind when Benny flees to the Fort after the Courier pursues him to the Tops, and is soon after found by the Courier. He can however, be found before Benny leaves, and if asked he will tell you that Benny should be on the main floor of the Tops casino.

Quests

 * Wild Card: Ace in the Hole: the Courier meets Yes Man for the first time. As there is no restriction on who Yes Man can help, the Courier can interrogate him to find all the details of Benny's plan, and even continue it him or herself.
 * Wild Card: Change in Management: the Courier must obtain the platinum chip, assassinate House, and install Yes Man's A.I. in the Lucky 38 mainframe.
 * Wild Card: You and What Army?: the Courier must travel east of the Colorado to The Fort and activate an army of securitrons locked away in a secret Vault.
 * Wild Card: Side Bets: the Courier must meet with the various factions of the Mojave and decide who will be spared in the upcoming battle.
 * Wild Card: Finishing Touches: the Courier must convince Julie Farkas to support an independent Vegas, (optionally) protect President Kimball against an assassination attempt and use an override on the El Dorado Substation in order to power the Lucky 38 and allow it to broadcast the securitron operating system upgrade.
 * No Gods, No Masters: the Courier must power up the secret Vault, allowing the securitrons within to break out and crush the Legion, before convincing the NCR to leave the Dam to Vegas - by force, if necessary.

After speaking to Yes Man, the Wild Card series of quests will begin. The player can choose to continue Benny's plans, and start the Wild Card: Change in Management quest. This quest chain leads to No Gods, No Masters, where the player will take control of the Dam and later, Vegas.
