Fallout Tactics: Brotherhood of Steel takes place in the American Midwest , primarily in and around Chicago and the surrounding Illinois region , in the year 2197–2198.

Where the game is set

  • The story follows the Eastern Brotherhood of Steel as it expands its territory around Chicago , fighting mutants, raiders, and other hostile factions in the ruins of the Midwest.
  • Missions and locations span ruined cities, bunkers, military installations, and wasteland outposts in Illinois‑style settlements, giving a gritty, tactical‑combat feel across a mid‑American post‑apocalypse.

Timeline context

  • The events occur 35 years after the original Fallout (2161) and 44 years before Fallout 2 (2241) , placing it firmly in the early‑to‑mid 23rd century of the Fallout timeline.
  • This makes Fallout Tactics one of the earlier canonical entries in the series’ chronology, focusing on the Brotherhood’s expansion rather than Vault‑dweller stories.

If you want, I can also list some of the key in‑game locations (like bunkers and towns) that appear in the campaign.
