Veni, Vidi, Vici

 is a 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. You will confront the general and with a speech check of 85 you can convince him not to fight. 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. I suggest you get many stimpacks 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 gaurds 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.
