The intensely graphic description of what just happens to the player character when you walk down the Master's hall.
Crowning Building Of Awesome: For the bad guys. The Cathedral is a huge stone building that seems perfectly intact, leading you to wonder how it avoided devastation. The answer? It didn't. They built it themselves. And just in case you don't get the awesome, there are very few intact bricks you can find in the wasteland, and they built a motherfucking cathedral. And then you had to go and make it a crater.
The overseer gets one if the player ends up with the bad ending. When vault 13 is overrun by the super mutants he goes out blasting several of the mutants to hell with a mounted turret before being overwhelmed and beaten to death offscreen.
