Detailed walkthroughEdit

First, to initiate the quest, the player must have finished Arizona Killer and by then have access to start "Veni, Vidi, Vici" (which is a final test that results in the Legion attaining victory and control of the dam and New Vegas with the rest of the Mojave). You will start off in Legate's camp, and must make your way to the Legate's war tent where Lanius will open conversation with the Courier, before the attack on the dam. After the conversation with Lanius, the Courier will be summoned outside the tent where he will witness dozens of legionaries preparing to attack and then march towards Hoover Dam. The Courier must then follow the path of the legionaries, past the gate from the Legate's camp to the dam.

The player must fight their way along Hoover Dam to the entrance to the visitor center. Along the way, if the player completed the quests For Auld Lang Syne and Volare!, the Enclave remnants and Boomers will arrive to assist the player. NCR snipers are positioned atop inaccessible towers and must be killed from a distance. Near the visitor center, a handful of Great Khans will assist the player and the Legion if the player did not break their alliance with the Legion in the quest Oh My Papa. At the visitors center the player must enter the Hoover Dam power plant 01 area and fight their way past NCR's forces to the 04 power plant, where the entrance to Oliver's compound can be found.

When the player enters the compound, General Oliver immediately initiates dialogue. With a Speech check of 100, the player can convince him to retreat for the sake of his men. All other options result in a fight. Oliver and the NCR Veteran Rangers with him flee to the second floor as several rank-and-file NCR troopers attack the player. The player must navigate the floor, which includes several force fields that cannot be passed, to reach the balcony where the stairs to the second floor are. Here the player must defeat the two Veteran Rangers, and the floor is heavily booby trapped with numerous grenade bouquets and bear traps, among other dangers. At the end of the room the player will find the stairs to the third floor, where Oliver ambushes the player with several NCR heavy troopers.

When Oliver and all the NCR soldiers in the compound are dead, the player is given the objective to report to Lanius. He will appear before the player upon leaving the compound, congratulating the player on seizing the dam for the Legion and telling them they will be rewarded for winning the Mojave. The ending then plays.

Behind the scenesEdit

  • "Veni, vidi, vici" is Latin for "I came, I saw, I conquered," and was Julius Caesar's description of the short Battle of Zela that he fought against Pharnaces II of Pontus.
  • "In hoc signo vinces" is, likewise, Latin for "In this sign, you will conquer." It was most famously uttered by Emperor Constantine, the first Christian Emperor, who saw the sign of the Cross in the sun and uttered the phrase. By splicing in "taurus," Caesar is exhorting you to conquer for the symbol of the Bull.
  • If Arcade Gannon is following as a companion, he will leave upon arriving at the Legate's camp. Attempting to talk to him again will result in him saying "Why don't you make like Odysseus and get lost?" This is a reference to Homer's The Odyssey in which Odysseus (Ulysses) treks 10 years across the Aegean Sea, trying to return to his home island of Ithaca following the Trojan War, but gets lost and side-tracked numerous times along the way.
