Adams Air Force Base
Fallout 3’s add-on Broken Steel added an extension to the ending of that game. In it, players are given some much needed closure to Fallout 3’s original, somewhat ambiguous ending. Following the events of that ending you find yourself in the Citadel, the Brotherhood of Steel’s base of operations. A new series of main quests sets in motion a final, exciting assault on the evil Enclave and their main settlement, the Adams Air Force Base.
After lots of shooting and mayhem at the base, you eventually reach a satellite tower where you are given the ability to launch an orbital strike on a location of your choosing. The terminal gives you two options: the Adams Air Force Base–effectively destroying the Enclave, or the Citadel–if you want to be especially evil. While lots of evil karma and the ire of every member of the Brotherhood of Steel is nice, choosing to destroy the Citadel only rewards you with the base’s smoldering ruins upon your return. Choosing the Air Force Base allows you to watch the missiles rain down and level everything in sight. Good guys like explosions, too!
