Hologram (Fallout: New Vegas)

Holograms are characters in the Sierra Madre $$

Gameplay
They can be destroyed 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, 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.

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.

Locations
Holograms are found throughout the Sierra Madre.

Appearances
Holograms appear in the Fallout: New Vegas add-ons Dead Money and Old World Blues, in the Z-38 Lightwave Dynamics Research.

Bugs
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.
