what fallout game takes place in colorado

The only official Fallout game that directly takes place in Colorado is Fallout Tactics: Brotherhood of Steel (2001).

How Colorado appears in Fallout

• Fallout Tactics: Brotherhood of Steel
  • The campaign follows a Midwestern Brotherhood splinter group that eventually operates in and around Colorado , especially the Cheyenne Mountain / Vault 0 area.

* Colorado is key to the main plot because the supercomputer called **the Calculator** is housed in **Vault 0** , located in Cheyenne Mountain.

• Mentioned but not main setting
  • Denver, Colorado is referenced in Fallout: New Vegas – Lonesome Road as a ruined city known as the “Dog City,” but you never actually visit it in‑game.

So if you’re asking “what Fallout game takes place in Colorado” , the answer is Fallout Tactics: Brotherhood of Steel , with later games only referencing Colorado rather than using it as the primary playable setting.
