The game's introduction establishes the setting, mood, and narrative through dialogue between two characters, as the narrator discusses how the player character will change history after being shot in the head. Production techniques like voice acting and dialogue were used to create specific soundtrack elements in the game's introduction that set the scene and backstory.
