Hologram (Fallout: New Vegas)

Holograms are three-dimensional projections which sometimes interact with the player and non-player characters in Sierra Madre in 2281.

Gameplay attributes
The security holograms can be difficult to deal with, no matter your level or equipment used. They can be "destroyed" only by destroying or disabling their respective emitter. They can alternatively be reprogrammed to patrol different layers of the casino.

Holograms are present in the Villa, though most are non-hostile and you even have the option to activate several security holograms to guard Dean Domino during the quest Trigger the Gala Event. There is only one hostile hologram located in the Villa, it is located inside the Villa clinic. Holograms are the primary enemy when you first enter the Sierra Madre Casino & Resort, and you are not able to shut them down due to the emitters not being accessible, so instead you must use the terminals to reroute their patrols. Later on, when you reactivate the power in the casino, the security holograms disappear and are replaced with casino floor managers, a cashier, bartender, and a lobby greeter. Reprogramming the starlet holograms in the Executive suites prevent them from becoming hostile. A hologram of Dean Domino can also be used to shut down the security protocols in the Tampico Theater. Holograms are also present in Sierra Madre vault, in the last room before you enter the vault itself.

Hologram
This version of the hologram is the main security version. They appear in the Villa clinic and in the Sierra Madre Casino & Resort. It appears to be wearing Sierra Madre armor. The emergency defense system activated these holograms when the bombs dropped, and they are still actively patrolling.

Some starlet holograms also function as security holograms (Executive suites), and have the same stats, differing only in appearance and their unique ability (amongst holograms) to open doors.

Hologram (female)
Generic friendly female holograms. One is seen during the quest Curtain Call at the Tampico.

Starlet hologram
All the starlet holograms have the appearance of Vera Keyes. Unlike security holograms, Starlet holograms don't always attack the player, the exceptions being the hologram in Vera's room, and in the Executive suites. Outside the Sierra Madre Casino & Resort there's an additional starlet hologram, featured very prominently in the central non-functioning Villa fountain. If shot with the holorifle, they will instantly turn hostile.

Hologram vendor
Throughout the Sierra Madre there are several vendors from which to buy various items, such as food and drinks. Vendor locations include the casino and cafe. This type of hologram will ignore attacks, and will not turn hostile towards the player character.

Although they have no caps (being pre-War tech), the vendors carry large quantities of pre-War money, which you can use to barter with them.

Dean hologram
The Dean hologram is a stage-performing hologram found in The Tampico theater at the Sierra Madre Casino & Resort. During the quest Curtain Call at the Tampico, the hologram of Dean Domino will perform the song "Something's Gotta Give", on the Tampico stage. After the song, he will receive some applause from hologram spectators, and subsequently disappear from the stage.

Locations
