|The following is based on Fallout Tactics and some details might contradict canon.|
Canyon City was a town near the Kansas-Colorado border, where the Calculator set up robot repair station 10.92 around 2198. It is in this station that damaged robots were mended and parts of destroyed robots were rebuilt and combined to form a whole.
When the Brotherhood of Steel discovered it, they decided that this repair plant must be permanently shut down. This station was too huge to destroy, as it would have taken too much time and resources to reduce this station to rubble, so the Brotherhood disabled it instead, by destroying the power nodes. Terminals containing some information about the Calculator and Vault 0 were also found. It was the Warrior who successfully destroyed the power nodes and discovered the truth of what the Calculator was.
The mission in Canyon City is to destroy six power nodes with simultaneous explosions to shut down the robot's repair plant.
Canyon City appears only in Fallout Tactics.
Behind the scenesEdit
The only real-world Canyon City is in Oregon. The town seen in Fallout Tactics may in fact be a renamed Cañon City, given its location on the map (very) roughly corresponding with the real-world Cañyon City, Colorado City.
