Hologram

A hologram is a type of technology developed before the Great War.

Background
Hologram technology is believed to have originally stemmed from Stealth Boy research in a scientific drive to match Chinese stealth suit technology. Hologram technology never achieved the same level of prominence, due to excessive energy constraints. Big MT's "Hologram Project," was conducted at the Z-38 lightwave dynamics research facility. The functionality of the holograms were limited to greeters, mechanisms for surveillance, and security. If the security hologram's emitters are destroyed, they longer pose a threat.

If the holograms detect intruders, their silhouette changes to yellow, and then red before attacking. If the target evades the hologram, it will resume its normal routine after some time. Service holograms providing the automated systems of the Villa and the casino such as by providing vending points or casino games, but could not engage in security functions.

Appearances
Holograms appear in the Fallout 3 add-ons Point Lookout and Mothership Zeta, in the Fallout: New Vegas add-ons Dead Money and Old World Blues, and in Fallout: Brotherhood of Steel.

Behind the scenes
A hologram was planned for inclusion in Van Buren.

Fallout: New Vegas

 * When seeing a hologram and then quickloading the game, the hologram's color can go dark. They still flicker, but they won't be blue anymore, and it may be hard to see them. Only way to fix this is to open console click on the hologram till the hologram non-player character's ref. ID shows up and type "resurrect."
 * They can be killed with gas bombs, frag grenades or C4 and give 10-20 XP.
