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 not be played if having entered the wrong code when trying to activate the purifier (the purifier will be destroyed in an explosion that way). Unlike previous Fallout games, there is no ending narration for individual towns visited during the game. The only thing influenced by side quests is the choice of some of the slides shown during the ending cinematic.
