Fortification Hill

 is a Caesar's Legion base where the slavers keep an eye on the Hoover Dam. This is also the location where the Platinum chip is used to install the upgrades to the Securitrons. The Fort is built above Mr. House's secret bunker (see second note) The Fort can be reached by taking the barge at Cottonwood Cove. The barge, itself, might at first just appear to be part of the dock--and you might not think anything's there--it's merely a flat floating 12x12 raft-like "boat" roped up beside the dock. This barge can be taken whether the Legion soldiers at the cove are friendly, enemies, or even dead (although this is not recommended). If you have not yet been invited, the guards at the Fort may be hostile. If you travel to Cottonwood Cove with Boone, beware. He will immediately attack all legionaries on sight, causing them to turn on you. This will happen even if you have been invited.

Notable Loot

 * 2000 caps in the very hard locked footlocker in Caesar's room.
 * A displacer glove which Caesar is wearing.
 * Lupas brain (which is used for Nothin' But a Hound Dog)is in Lupa and you have to kill Lupa to get it. You may speak to Antony, who is seen standing beside her, in order to fight her in the ring. Alternatively, attacking Lupa will alert the camp so it is good if you are planning to kill the entire camp anyways. It increases Rexs' health to 550 instead of 350.
 * Caesar's Armor

Bugs

 * When you enter the fort, sometimes you will see excessive tearing of the screen everywhere.
 * Most companions will glitch between Cottonwood Cove and the Fort, thus making it impossible to go into Caesar's tent. This may be possible to solve by having your companions wait in Cottonwood before taking the barge.  Once there, fast travel back, have them follow you, then fast travel to the fort.
 * You may not regain all your weapons upon leaving the fort, so make sure you save before you attempt to leave.
 * Boone may not warn you prior to leaving Cottonwood Cove that he will murder everyone in sight once you reach The Fort.
 * If you decide to kill everyone at the Fort a glitch will appear when going in and out of the drawbridge, if you see previous kills lying on the ground with no armor on they will appear with different supplies every time you go in and out of that location.
 * if you save before going in to the fort the file may become corrupted and cannot load again and if you die inside the fort and you load your save game in entering before the fort the game loading screen will freeze thus the game become corrupted
