The Apocalypse

The Apocalypse is a quest in the Fallout: New Vegas add-on Lonesome Road.

Quick walkthrough
This quest appears after you deal with Ulysses and decide the fate of the nuclear missile. Choosing any option other than canceling the launch begins this quest and fails The End. Leaving the temple and watching the DLC ending completes the quest. On returning to the Mojave after the ending slides, a nuclear explosion can be seen in the general vicinity of whichever territory was targeted (or both, if you chose to nuke both Legion and NCR).
