Veni, Vidi, Vici

 is a final quest in Fallout: New Vegas.

Quick Walkthrough
You are asked if you are ready for the final fight and if 'yes' is chosen you are moved to the legate's camp. After some dialogue with the legate, you will storm the Hoover Dam, where your mission is to kill General Oliver. The fight consists of getting through four areas of the Dam with the various factions you have befriended helping you. Assuming you are going to kill him head to the final area which is a room full of traps with a platoon of NCR Veteran Agents. Up the stairs the general is in the room ahead waiting for you with several Heavy NCR Troopers. After killing them kill the general. Leave the room and the Legate will congratulate you for your job spilling blood and the game will end.

Detailed Walkthrough
On the last section where you have to kill the general, there are many soldiers. It is suggested you get many stimpaks and good weapons before you enter this area. You need to make your way around the force fields. When you do this you need to go to the second level. On this level you will need to kill the generals guards but keep an eye out for the many traps. After you kill these, proceed to kill the general. Leave the room and you will be congratulated for spilling blood and the game will end.

Bugs

 * When entering the Hoover Dam area with Rex and Cass or Rex and Lily as companions, both automatically go unconscious.
 * When on the second floor the game will freeze if trying to enter VATS as soon as you walk up the stairs, though it may not if a valid target is present.
 * If you choose to wait before entering legates camp, you might not be brought to the camp when you finally choose to go. Instead it will simply bring up the prompt, and then not do anything after choosing "yes".
 * During the confrontation with General Oliver, after killing him and all his guards the quest will not move on to tell you to exit the room. Despite searching every area for any lingering enemies no red tick(s) will appear. Simply load a save from before the conversation with General Oliver and try again.
 * After killing General Oliver and the rest of his Troops, the game will prompt you to exit through the first floor. The game may freeze (leaving you inside the room) when activating the door.
 * During the confrontation with Oliver and his troops the player must navigate through a room full of mines, tripwires, and other traps. If the player quicksaves and quickloads all the mines previously detonated will detonate again.
 * It is possible for a NCR ranger to become friendly in the office trap area. He will flee from the player, making the objective of killing all NCR soldiers much more difficult.

Behind the scenes

 * "Veni, vidi, vici" is Latin for "I came, I saw, I conquered," Julius Caesar's description of a short war in what is now Turkey.
