Raven Rock

 is the Enclave's main base of operation in 2277. It can be found in the northwestern part of the Capital Wasteland. The base itself is not accessible during freeform play; you arrive here after Finding the Garden of Eden and escape during The American Dream, and the entrance seals behind you. Depending on the player's choices throughout the game, a few named NPCs might be found while moving about Raven Rock. Nathan Vargas from Megaton can be found warning the player character that the Enclave "aren't who they say they are." Anna Holt can also be found in a room near John Henry Eden's office.

The player character may destroy Raven Rock through a speech check with President Eden. This seems to hold little relevance in gameplay as the Enclave presence at Project Purity is just as strong and organized as it would be had the player character not destroyed Raven Rock, but a plausible explanation is that the highly militaristic Enclave has prepared evacuation drills for abandoning the base with minimal loss of men and material - Autumn may also have been preparing to leave for some time, since he seems to require very little to finally push him into rebellion against Eden at the time of the Vault 101 Dweller's arrival. The player may inform Elder Lyons of Raven Rock's destruction, but again this only results in dialogue and no visible difference in the Enclave's performance. Also near the exit there is a caged deathclaw.

In the add-on pack Broken Steel Raven Rock will be destroyed by Liberty Prime and there is no way to get back into the base.

Description
Raven Rock is a hardened underground fallout shelter originally built to house high ranking military and political personnel in the event of nuclear attack. It is powered by a General Atomics reactor and gets its water from deep underground wells.

Notable Loot
There is an immense amount of loot available at Raven Rock including the rare Tesla Power Armor, Plasma Rifles, Enclave Power Armor, Enclave Hellfire Armor, AER9 Laser Rifles and Gatling Lasers.

The Energy Weapons Bobblehead is located in Sector 2C in a room to the northwest. If you miss it during your visit to Raven Rock you will be unable to retrieve it later. However, on the PC version you may regain access to Raven Rock with the console.

The Bobblehead is located on the second floor (Raven Rock - Level 2) in Colonel Autumn's room to the northwest. After opening one of the large metal doors, the player will be confronted with two doors, one with two enemies behind it. The Bobblehead is behind the western door. The player should not enter the Control Room before retrieving the Bobblehead, as the doors will lock permanently.

You will also find a few electric barriers guarding various ammo and first aid boxes. These barriers can only be by-passed by hacking terminals- usually average- but it is possible to obtain their loot with out hacking, simply use the same tactics used to retrieve Colonel Autumn's 10mm Pistol. That is to say, go third person, then stand close to the barrier and hold down the button, or key, that allows you to change perspective, to rotate the camera. Do so until you see the option to loot the crates, while still holding down the button or key.

Bugs

 * All glitches have been moved to the discussion page. The discussion tab at the top of the page will take you there.


 * The outer hatch can be blown off from the outside by small arms fire (but not grenades). If you enter the complex (before The Waters of Life quest), you will be blocked from further entry by an invisible wall. When you leave, you will trigger the event where Colonel Autumn's Vertibirds flee the compound. If you go back and exit one more time, the Vertibirds will be stuck to the ground on top of Raven Rock. Just climb up there and you can study them closely. But you can not do anything to them. (You can blow them up! I did this trick and fired at them and they eventually blow up and have the same HP as normal Vertibirds) thumb|300px|right


 * Upon returning to Raven Rock after completing the associated quest, one finds Enclave soldiers in fleeing mode. This becomes a respawn area.


 * In addition to the three fleeing Enclave Soldiers [non-fleeing?] a fourth soldier may be found who carries no weapons and has no helmet, he appears to wear standard Enclave Power Armor but his inventory is empty. He will walk around the Raven Rock entrance and sometimes follow the fleeing soldiers. Having no real armor or weapons, he is amusingly pathetic but quite hostile.[trigger for event?] [360]


 * There's two holes in the passibility that makes you fall through a wall and end up on another floor at the basement. It's located in level 2 in the room with the Science officers on the wall adjacent from the stairwell and the other wall that doesn't have a doorway or stairwell. If you ease up to the wall you can stare out and look at the various things that are probably in other rooms


 * There is a glitch where if you convinced Eden to self-destruct, and you fast travel back to Raven Rock with Fawkes as a follower at a later time, Fawkes will get stuck under the level. You can solve this by moving away until he starts following you and he will re-glitch back onto the surface.


 * If you want to get back into Raven Rock and havent finished, go outside but not so much that the door closes, pull out a 10mm pistol or other small weapon and shoot the middle of the door twice. It is different to shooting it when the door closes because when it does the invisible wall will be in front of it making it impassable. Thanks to people at gamefaqs for telling me to put this on the wiki!

Appearances
 only appears in Fallout 3.

Behind the scenes

 * Raven Rock Mountain Complex is a real-world government complex that became operational in 1953.
 * is the name of a settlement on the island of Solstheim in the Bloodmoon expansion of Bethesda's The Elder Scrolls III: Morrowind, and, oddly enough, is located near the Raven Rock in Fallout 3 (Northwest corner). It is also referred to in The Elder Scrolls IV: Oblivion by some people on the Waterfront.
 * is also the real-world name of a hiking trail found in Bluemont, Virginia and a state park in North Carolina.
 * is located in upper left-hand corner of the map in Fallout 3, roughly in the area of McLean, Virginia. This area is home to many sensitive intelligence installations, like the headquarters of the CIA and Booz Allen Hamilton.  The area is home to many diplomats, members of Congress and high-ranking government officials.
