Calculator

The Calculator was the computer that controlled Vault 0. Unlike the ZAX computers, it was not a real artificial intelligence, but rather a cyborg, because it was connected with several human brains.

According to official information, one advantage the Calculator had over normal computers is the electro-organic linking terminal. The tests concluded that the CPU can share tasks and receive data from pseudo cryogenic stored brains that were maintained in an oxygenated tank.

These brains were initially that of lab rodents, but calculations eventually indicated that human brains could be preserved in the same fashion. The brains were fed specifically formulated nutrients to sustain suspended life. In turn, they assisted the Calculator's CPU in Vault management, including life support, food production and distribution, Pacification Robot protocol, and Vault-0 defenses.

This neural network was also meant to assist in Vault-0's primary function: To initiate Mankind's post-war rebirth. When outside temperature, radiation levels, and poison particle counts returned to acceptable levels, Vault-0 was to remotely activate the Exodus Protocol, which would initialize the integration of all Vault Dwellers onto the planet's surface.

However, the Exodus Protocol could also be triggered by breach of the Vault defenses, as was the case when the Eastward-fleeing supermutants stumbled upon the Vault. Unfortunately, much of the surviving vault population had become brain damaged due to the lack of backup life support systems; ironically enough, such systems were scrapped during streamlining of the vault's construction, to be replaced by leisure facilities and provide pay raises to senior committee members.

Although the Calculator had begun rapid expansion and had attempted to eliminate the Midwestern Brotherhood of Steel, Vault 0 was breached by brotherhood forces, and the Calculator, defeated.

Behind the scenes

 * Incidentally, the story of Tactics went through a lot of revisions. For example, my original concept for the main villain, the Calculator, was for it to be a completely unfeeling automated system, not even a computer so much as an engine designed to tick over and perform certain tasks after doomsday. Totally implacable, and therefore the fault of everything bad that happens is still in the hands of the humans. - Ed Orman (NMA interview)

Mission walkthrough
When your squad reaches the Calculators room the Calculator will raise indestructible barriers around itself. You will need to destroy the brains near it to access the first door near the Calculator (before destroying the brains read solutions 1 and 2). Behind it you will find some robots and another brain. If you destroy that brain the second door opens. There are three such doors each containing a brain. If all the brains are destroyed the barriers lower allowing you to access the Calculator and listen to its offer. There are four ways to end this mission each resulting a different ending cinematic.


 * 1) Sacrifice your character to fix the Calculator with good karma. Since destroying the brains in the calculators room gives you a lot of negative karma you need to place explosives near the brains so you are not attacking them directly (This presumes you already had good karma at the beginning of this mission).
 * 2) Sacrifice your character to fix the Calculator with negative karma. Destroy the brains by just shooting them, each will give you negative karma and of course will open the necessary doors.
 * 3) Do nothing and wait or destroy the calculator by attacking it. Brains can be destroyed any way you like (the Calculator can be destroyed without alerting it, it can be shot from outside the room avoiding the three rooms with brains).
 * 4) Convince General Barnaky to sacrifice himself. This only requires you to talk to him after the Calculator has made the offer.

Appearances in games
The Calculator appears only in Fallout Tactics, where it is the main enemy of the Brotherhood.
