Fallout: New Vegas has four main outcomes for Hoover Dam, and the ending slideshow that follows also covers dozens of companions, towns and factions, each with its own conditions. The main outcome is set by which of four final quests you complete. The rest of the slideshow depends on choices you made earlier. This guide covers both.

Checked October 21, 2026 against the Fallout Wiki’s page on the endings, which transcribes the in-game slides and their conditions, with the Independent-route details cross-checked against the wiki’s Strip endings page and Game8’s ending guide. It is a community-maintained wiki.

The four main outcomes

Outcome Final quest (per the wiki) What happens at Hoover Dam
NCR Eureka! The NCR wins the second battle and takes control of the Mojave, then arranges to annex the Strip and Freeside
Mr. House All or Nothing His Securitron army takes the dam and the Strip and pushes out both the Legion and the NCR
Caesar’s Legion Veni, Vidi, Vici The Legion pushes the NCR out and occupies New Vegas. The tone depends on whether Caesar is alive (see below)
Independent No Gods, No Masters You drive out both armies and the city stands on its own. The result depends on the Securitron army (see below)

Two of these have a built-in variation:

  • Legion: Caesar alive or dead. If Caesar survives the quest Et Tumor, Brute?, the Legion’s slide shows Caesar entering the Strip in triumph, with much of the population enslaved. If he dies there, the slide shows his Legate crowned as the new Caesar, destroying anyone who resists and killing and enslaving a large part of the population.
  • Independent: the Securitron army. If you finish the Independent route without upgrading the Securitron army, the slide describes anarchy in the streets before the city settles. If you upgrade it, part of the army keeps order and the slide describes minimal loss of life. The Strip endings page and Game8’s guide give the same split.

The ending also depends on your karma. A separate slide about the Courier has fifteen versions, one for each combination of karma and outcome, such as being honored by the NCR with the Golden Branch, or by Caesar with a golden coin.

How choices before the end change the other slides

After the main outcome, the game plays slides for companions, towns and groups. Many have conditions that tie to the final quest you picked and to earlier quests. Examples from the wiki:

  • The Followers of the Apocalypse. On the Legion route, they are allowed to leave if Caesar is alive and are exterminated if he is dead. On the NCR route, the outcome depends on whether you convinced them to support the NCR. On the Independent route, they are overwhelmed by patients.
  • The Boomers. Whether you completed Volare! changes their slide under each outcome. For example, if you did not complete it and the Legion wins, they are enslaved. If you did and the Legion wins, Caesar leaves them alone.
  • The Brotherhood of Steel. Destroying the Hidden Valley bunker gives a slide that overrides the others and ends the Mojave chapter.
  • Arcade Gannon. If you sell him into slavery as Caesar’s doctor during Et Tumor, Brute? and the Legion wins, his slide ends in his death. A different slide plays if Caesar died first, and another if the Independent route wins. Otherwise, his slide depends on the quest For Auld Lang Syne and the advice you gave him.
  • Craig Boone. The quest I Forgot to Remember to Forget decides whether you convince him to make amends over Bitter Springs or leave him vengeful, and each choice changes his slide under every outcome.
  • Companions who die. Dying overrides the other endings for Raul, Veronica, Arcade and several others, according to the wiki’s notes.
  • Towns. Goodsprings, Novac and Primm each have slides tied to local quests and to the final quest. For example, Primm’s slide depends on who you made sheriff.

Can you keep playing after the ending?

No. The wiki says the game ends after the slides and cannot be continued, so the options are to reload a recent save or start a new game. Plan for this before the second battle of Hoover Dam. The same page’s trivia notes describe console-command workarounds that let you roam afterward, but we did not test them and would not rely on them. The downloadable expansions have their own endings, listed on the wiki’s separate pages.

One trivia point from the same page: the slideshow format came from Josh Sawyer, who thought it was easier than making videos in the engine.

What to plan around

  • If you want the Legion route, decide what happens to Caesar before you start Et Tumor, Brute?, because it changes the Legion slide and several others.
  • If you care about a particular companion, check their quest conditions before the final quest, since some slides depend on their personal quest.
  • If you want the Independent route, decide whether to upgrade the Securitron army, because it changes the main slide.
  • If you want to save a faction, note which of its quests control its slide. The Boomers and the Brotherhood are the clearest cases.
