Fallout 3 endings

Just like the intro, the ending is narrated by Ron Perlman. The first and final parts are the same for each player, the 3 middle parts depend on their choices, Part 4 may be not played if the player entered the wrong code when trying to active the purifier(the purifier will be destoryed in an explosion that case).

Unlike previous Fallout games, there is no ending narration for individual towns visited by the player during the game.

Part 1
And so it was that the lone wanderer ventured forth from Vault 101, intent on discovering the fate of a father who had once sacrificed the future of humanity for that of his only child.

High Karma
The Capital Wasteland proved a cruel, inhospitable place – but the lone wanderer refused to surrender to the vices that had claimed so many others. The values passed on from father to child – selflessness, compassion, honor – guided this noble soul through countless trials and triumphs.

Low Karma
The Capital Wasteland proved a cruel, inhospitable place – and the lone wanderer ultimately surrendered to the vices that had claimed so many others. Selfishness, greed, cruelty – these were the values that guided a lost soul through countless trials and triumphs.

Neutral Karma
The Capital Wasteland proved a cruel, inhospitable place. [Narration ends on a scene from Moriarty's and proceeds to part 3]

Player dies
But it was not until the end of this long road that the lone wanderer learned the true meaning of that greatest of virtues -- sacrifice. Stepping into the irradiated control chamber of Project Purity, the child followed the example of the father, sacrificing life itself for the greater good of mankind.

It was not until the end of this long road that the lone wanderer was faced with that greatest of virtues -- sacrifice. But the child refused the follow the father’s selfless example…instead allowing a true hero to venture into the irradiated control chamber of Project Purity, and sacrifice her own life for the greater good of mankind.

Player doesn't side with Eden
Thankfully, when selected by the sinister President to be his instrument of annihilation, the wanderer refused. Humanity, with all its flaws, was deemed worthy of preservation. The waters of life flowed at last – free and pure, for any and all. The Capital Wasteland, at long last, was saved.

Player sides with Eden
Sadly, when selected by the sinister President to be his instrument of annihilation, the wanderer agreed. Humanity would be preserved, but only in its purest form. The waters of life flowed at last – but the virus contained within soon eradicated all those deemed unworthy of salvation. The Capital Wasteland, despite its progress, became a graveyard.

Part 5
So ends the story of the lone wanderer, who stepped through the great door of Vault 101, and into the annals of legend. But the tale of humanity will never come to a close, for the struggle of survival is a war without end. And war… war never changes.
