Vault 0 (Vault Zero) is a location in Fallout Tactics.


Unlike most Vaults involved in the Vault Experiment, Vault 0 was not an experiment in human behavior. It was constructed by expanding and reinforcing the Cheyenne Mountain Complex in Colorado and was by far the largest of the underground Vaults (by volume). If the interiors were so designed, Vault 0 could easily support a population of well over 100,000 people. Many of the areas that comprise the massive interior layout of Vault 0 were originally designed to be the size of (and were often compared to) aircraft hangars, warehouses and factories; these zones were for the construction of various machines that were ostensibly designed to serve the Vault Dwellers and the Enclave.

Vault 0 was a place where the geniuses of the pre-War United States could be kept in cryogenic stasis - their brains were extracted and frozen for the duration of their "residence" in this Vault. They were hooked up together to one big supercomputer called the Calculator, which was supposed to function in collaboration with the brains of these pre-War geniuses to design and nurture an ideal human society in a post-War U.S. by educating the survivors and residents. One should particularly note that this project goal differs from that of the Enclave in methodology. All the Vault's inhabitants were also using cryogenic stasis rooms to survive through many years of nuclear fallout.

Due to budget cutbacks by the Department of Defense (because of a false sense of safety as a result of the repeated drills), several important backup systems were not included to the neuro-link systems. This made the Calculator corrupted and instead of releasing the robots to make the Wasteland safe for humanity, the Vault 0 robots began to exterminate all life, completing the so called "pacification protocol". As for the unfortunate geniuses plugged in, most of them suffered severe brain damage, dementia, and mental retardation from a combination of age and prolonged radiation exposure (not mutation). Technology, it seemed, has not been affected by the ravages of nuclear radiation.

Vault 0 thus becomes the end-setting of Fallout Tactics, as the player character, the Warrior, and their team of Brotherhood of Steel Paladins have to stop the machine. The Warrior's squad came to Vault 0 after the nuclear explosion that opened the Vault door. There, they finally met the infamous Dagger Squad of the Brotherhood, which consisted of squad leader Paladin Lord Maximus, Tais, Maelyra, Khronis, and Phoenix. Dagger Squad aided the Warrior in defeating the first wave of Vault protectors, and then secured the lift which later could be used to enter the Calculator's chamber. However, the Vault power nodes were rendered offline after explosion, so the Warrior had to activate them. Going through security, living and cryogenics facilities of the Vault, the Warrior battles many robots and encounters remnants of Vault 0's citizens, who were revealed to be severely brain-damaged due to malfunctions in the cryogenic chambers. Ultimately, the Warrior activates the power nodes and proceeds to the lift, entering the Calculator's main lair.


Main article: Vault 0 (mission)

The mission in Vault 0 is to activate three power nodes throughout the vault in order to reach the Calculator.


  • The concept of Vault 0 is often considered inconsistent with the Vault Experiment from Fallout 1, 2, 3 and New Vegas.
  • The technology, aesthetic, and design of Vault 0 has nothing in common with other Vaults.
  • The Vault door is significantly weaker than any other Vault, having been blown open by a nuke, as opposed to Vault 87, which survived a direct hit.


Vault 0 appears only in Fallout Tactics.

Behind the scenes

  • The Cheyenne Mountain Complex is also the location of the fictional Military Strategic Defense Initiative, like the Sentient Computer System called "SkyNET" from the Terminator series of films. Many further Terminator references are made throughout the Fallout: Tactics. It is also a real military site; there is also a zoo ( on the other side of the mountain in real life.
  • The Complex was also used in the television series Stargate SG-1 as the base of operations for the fictional "Stargate" program, starring Richard Dean Anderson, a voice actor in Fallout.
  • Cheyenne Mountain remains a military base today and is located in Colorado Springs, Colorado. It is the location of most of the United States' missile targeting systems and missile defense systems.
  • This is also the housing for the W.O.P.R. super computer in the movie War Games.
