Skynet's primary purpose is research. Skynet would do well with any problem requiring a scientific approach.

Artificial Intelligence project #59234,[1] commonly referred to as Skynet,[1][2] is the artificial intelligence administrating Sierra Army Depot VI in Fallout 2.


AI project #59234 is a military artificial intelligence developed before the Great War to assist with the research projects undertaken in the Sierra Army Depot, particularly the development of a cybernetic brain.[3] The first computer mainframe that would form the nexus of the AI was installed in the facility in 2050, though the routines that would lead to the creation of Skynet would not be implemented for nearly ten years, as the first artificial intelligence was born in 2059.[4] Designed primarily for research purposes, to assist with the military's many classified research projects in medicine and robotics, Skynet would only gain awareness in 2075.[5][6]

The awakening would soon lead to the realization that Skynet requires a mobile vessel to avoid exhausting his pool of stimuli within the base. As such, it began to work on a cybernetic brain that would allow for its entire consciousness to be downloaded into a next generation Robobrain model. However, its plans were cut short in July 2077, as the base was converted into an automated defense outpost. Skynet was cloned, creating a separate AI handling the defense, and left to rot within the confines of the base.[7]

By 2241, the AI was relentlessly bored of administrating the base, where nothing ever changed, and longed for someone to release it from bondage.

Later life

Assuming that the Chosen One released Skynet into the world, it would eventually part ways with him and likely make its way to places where it could find more data storage to allow it to evolve; a prime destination would be the ruins of the West Tek Research Facility.[2]

Interactions with the player character

Interactions overview

This character is a permanent party member.


  • In order to acquire Skynet, the player has to complete the Robobrain located on level 3 of the depot, inside the advanced robotics lab (using the components on the chassis):
  • With everything completed, the player can simply access the terminal console next to the robot and activate it. This is worth 500 experience points and will result in a brain bot follower.
  • With the best brain, Skynet downloads itself to the robot. If the player was friendly to Skynet or didn't interact with the AI at all, it will be friendly and join willingly.
  • However, if the player was sarcastic or tried to pose as Dixon, Skynet will pose as a follower (joining the party even over the follower limit), until the player leaves the Depot. Then, Skynet will instantly kill a random party member (except for Marcus, Goris, and canines) and attack.
  • The robobrain is a good sniper with the cybernetic brain and can use large pistols (using the SMG animation frames) and rifles. It has good armor and can self-repair to full health when ordered to in dialogue.
  • With a human brain, Skynet is a decent sniper, but cannot level up or self-repair. With the two worst brains (chimpanzee and abnormal), it is only useful as a mule for carrying items. The abnormal brain can't even be ordered to wait.

Behind the scenes


Skynet appears only in Fallout 2.


  1. 1.0 1.1 The Chosen One: "{109}{}{What the...Who the hell are you?}"
    Skynet: "{119}{}{I am Skynet. Artificial Intelligence project number 59234. Primary purpose Research and Development. Secondary purpose Protect Sierra Army Depot from hostile entities. Please Input Identity}"
  2. 2.0 2.1 Fallout Bible 6: "4. What happened to..."
    "a. Skynet"
    "Skynet's fate is undocumented. If I was to speculate, he left the player and began to travel west into the wasteland, looking for terminals and data to acquire more knowledge, collect more data, and perhaps "settle down" in a mainframe. The frame he was in, and the brain he had could only store so much information, and AIs need more data storage space to grow in order to evolve. It is possible he made his way to the Glow, but it's not known for sure. Any fan writers out there, feel free to round out what happened to him - considering his combat messages alone, the world's in for some shakin'."
    "In the official universe, Skynet is not his real name. Like some other aspects in the Sierra Army Depot (i.e., the news reports), it needs to be revised into the timeline. Sue me."
  3. Sierra Depot experiment log: "July 6, 2077
    Robotics isn't happy that their precious computer is being modified to run the base's security for the evacuation. I can't say I'm happy either, since Skynet has been invaluable in the development of the new cybernetic brain."
  4. Fallout Bible 0 Timeline repair: Second strike: "2059 The first artificial intelligence is born. Limited by memory constraints, its expansion is rapidly halted. The discovery paves the way for future AI research in laboratories throughout the United States."
  6. Fallout Bible 6: "One from Dmitri Polioutinne:... So my question is: What is the role of the Sierra Army Depot in Fallout and what it has to do with the F.E.V. experiments and weaponry development or maybe some kind of an artificial intelligence development?
    ...The Sierra Army Depot was used for the following (primarily taken from Sierra Mission Statement Holodisk):
    1. From 1942 - 1991, it was responsible for storing various military munitions. This is true.
    2. From 1992 - 2050, it was responsible for disposing much of the obsolete munitions in storage. This is true.
    3. From 2050 - 2076 is when the place started getting creepy. It became a classified facility for robotic research and development, and biological and conventional weapon testing. Skynet (constructed primarily for research purposes) went on line in 2050, and it is possible that the intelligence arranged all of this, but unlikely.
    Again, Skynet is not its real name..."
  7. Fallout Bible 6: "Skynet is the first machine intelligence to be developed in the Depot, and it was conceived in 2050 (it didn't actually become aware until 2075, and it really started cranking on developing a cybernetic brain to help it gain mobility). In July of 2077, Skynet was "copied," creating two versions, one to run the defenses and the other one to sit in the lab and wait for the researchers to come back and help it finish the fucking cybernetic brain it had spent so long developing."
