* The intro to each game counts. The [[SoundtrackDissonance hopeful images of what once had been and what will come]] lead to the tracking shot that establishes just what [[CrapsackWorld kind of environment]] awaits the player, a cut to black, and then four words:

* The Gauss Rifle. Take your pick--''Fallout 2'' where the rifle will blow out half the torso of a target, an ''armored'' target, ''Fallout 3'' where it'll send an enemy spiralling through the air, or ''Fallout: New Vegas'' where the the unique version, the YCS/186, will ruin even an uber Quarry Junction Deathclaw Alpha Male's day.
