Veni, Vidi, Vici
You get this quest, if you've decided to help Caesar's Legion.
Once you've accepted the task, you'll be moved to [Legate's camp]. Go to Legate Lanius (M20:1) #1, who will assign you a task. Go to the camp's gate (M20:3), accompanied with some Legionnaires. Your main target is western power plant. Go ahead along with the dam, wiping out the NCR troops. You have to reach the Hoover Dam Checkpoint (M19:5) #2.
NOTICE: If you have an alliance with Boomers, their plane will bombard the enemy.
There is a Legion Decanus inside, which can assign you two optional tasks:
- release the Legion reinforcements waiting inside the intake tower (M19:6) #1;
- take out the snipers who've taken up position in the western portion of the dam.
If you decide to free Centurions, you can order them:
- [Speech 60] to focus troops along the dam top
- [Speech 80] to give you reinforcement in the power plant
Head to the Visitors Center (M19:3).
NOTICE: If you have an alliance with Great Khans, a small group of them arrives to help you #2.
Once you're inside the [Hoover Dam Power Plant], engage further heavy armored NCR troops and try to get down to the basement. Being on the level 04, go through the door leading to the General Oliver's office (M19B:2). The conversation will start #1. There are two ways to deal with:
- fight the General
- [Speech 100] convince the General to surrender
If you decide to talk to general, your skill [Speech 100] has to be maxed. Remember to choose only these conversation options, where nothing about killing is.
If you try to fight the General, he will run away leaving you with the force field in front of you. Turn left and make your way upstairs, behind the force field. When you're on the next floor, among some desks, watch out for the NCR guards, tripwires and bear traps. On the top floor you will meet the General Olivier #2 accompanied by NCR Heavy Troopers. Kill them all to complete the task.
Return to the compound entrance where you'll meet the Legate. Talk to him.
Congratulations, you've finished the game.
Depending on your actions during the game, there will be a variety credits at the end, outlining the current situation in Vegas.
