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 one even has 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 upon first entering the Sierra Madre Casino & Resort, and it is not possible to shut them down due to the emitters not being accessible. Instead, one must use the terminals to reroute their patrols. Later on, when the power is reactivated 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 entering the vault itself.
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.
All the starlet holograms have the appearance of Vera Keyes. Unlike security holograms, Starlet holograms don't always attack the player, the exceptions being those found in the Executive suites. Outside the Sierra Madre Casino & Resort there's an additional starlet hologram, featured prominently in the central Villa fountain.
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 can be used to barter with them.
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.
If one approaches the starlet holograms closely enough (without alerting them), the Courier can overhear Vera's voice calling Sinclair for help. This was her final moments before Vera took her own life.
The Starlet security holograms are capable of opening doors, unlike the normal counterparts.
Upon completing Dead Money, if one returns to the Executive suites without deactivating the hologram emitters, but instead has made them passive via the terminal, all Starlet holograms will reset, and become hostile upon spotting the Courier. It is suggested that the player deactivate the emitters the first time through, even if they have used the terminal, to prevent injury if they plan on returning.
With low intelligence, the Courier will struggle to interact with the hologram vendors and mistake them for "light men".
Upon reloading a save holograms may lose their blue light effect, making the hologram appear to be black. This does not stop the player from interacting with affected holograms, and can be fixed by reloading the area.[verified]
