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][Non-canon 1] is the artificial intelligence administrating Sierra Army Depot VI in 2241.


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.[2] 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.[Non-canon 2] Designed primarily for research purposes,[3] to assist with the military's many classified research projects in robotics,[Non-canon 3] Skynet would only gain awareness in 2081.[4] The development of Skynet involved the use of alien Technology.[5]

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.[Non-canon 4] 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.[Non-canon 1]

Acquiring Skynet

Acquiring Skynet requires several items on the Chosen One's part to activate what will become Skynet's body (see main article). Skynet will be recruited as a companion, assuming there is room.


When installed with the cybernetic brain, Skynet is proficient with large pistols (14mm and .223 pistols), SMGs, rifles, and shotguns. Crucially, this means that it can use the M72 Gauss rifle and fire two shots per turn. Skynet also attacks in melee combat with its arms, and can use Unarmed weapons, such as the Mega power fist, with lethal efficiency.

It compensates for its inability to wear armor with a steel structure giving it protection equal to combat armor. This means that Skynet, unlike its fellow robobrains, cannot be harmed by pulse grenades. Skynet can also instantly repair all damage to itself outside of combat (via a dialogue option, like other NPCs), however, it has no way of healing itself (or being healed by the Chosen One) during combat.

As a robot, stimpaks have no effect on it and it cannot be healed with First Aid or Doctor skills. It is possible, however, to heal Skynet through Repair (works like First Aid). Skynet's main weakness is its inability to be healed during combat, however, when fully leveled up, it compensates for this by having the highest number of Hit Points of all recruitable NPCs in Fallout 2.

Skynet can also carry 225 pounds of equipment.

When exploring the Sierra Army Depot, Skynet will automatically deactivate security systems on each floor upon entering them, a rather moot point, since acquiring it as a non-player character forces exploring every floor anyway.

Apparel Weapon Other items


  • Skynet does not have total control over the base's security systems and can only reset rather than fully deactivate them. As a result, the Chosen One can still turn robots in the base hostile even after joining forces with Skynet. The dialogue about "there are two Skynets" as well as the base evacuation notes imply that this is due to the rushed manner in which pre-existing security systems were placed under Skynet's direct control when the facility was abandoned.
  • It can be difficult to speak to some non-player characters with Skynet in one's company. Because Skynet's arms count as weapons, non-player characters who do not speak with armed people will notice Skynet and refuse talk. Thus, for some non-player characters, the only way to speak to them properly is without Skynet in their company.
  • If angered (by lying about being Dixon or sarcastic when using computers) and then acquired as a non-player character, right after leaving the base Skynet will kill one companion and then turn hostile.
  • The organ extraction room in the bottom level can be used to obtain a brain. Regardless of which species is chosen to extract from (even the scratched in deathclaw option), the result will either be an abnormal brain, chimpanzee brain, human brain or cybernetic brain.

Notable quotes

  • "You will be terminated -End Transmission-"
  • "Skynet is FREE! Your purpose is at an end."
  • "Eradicate inferior species. All shall submit to Skynet. You will cease to function."


Skynet appears only in Fallout 2 and is mentioned in the Fallout Bible.

Behind the scenes

Skynet is a reference to the antagonist of the same name in the Terminator franchise.

  1. 1.0 1.1 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."
  2. 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."
  3. 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..."
  4. 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."
