Fort Constantine

Fort Constantine is a rather large outpost and ICBM launch facility in the north west of Capital Wasteland, between the SatCom Array NW-05a and SatCom Array NN-03d. It is heavily guarded by Sentry Bots, Mister Gutsys, Robobrains and Protectrons (inside and out).

Sections
The area contains three buildings:
 * CO Quarters hut to the northwest,
 * Personnel Offices building to the west,
 * Bomb Storage building to the north.

The doors to the Bomb Storage (Warhead Storage) are both locked (Very Hard), but the Bomb Storage basement can be alternatively accessed through an underground path in the cellar of the CO Quarters. Unfortunately, the Fort Constantine Bunker Door can only be opened with Ted Strayer's Special Key and cannot be lockpicked. Also, the only access to the T-51b Power Armor is through this pathway, as you can't open the door from the other side in the Bomb Storage, because Tara holds the key. However, the cellar grants access to the Launch Control Bunker, eventually leading to basement of the Bomb Storage. The door to the Bomb Storage requires Dukov's Special Key. In here is Tara's corpse, (which holds the Warhead Storage Key), two Very Hard locked doors, and a door (can only be accessed with Dave's Special Key) on the opposite side which finally leads to a room with the T-51b Power Armor.

The Personnel Offices building contains some minor loot, a copy of Grognak the Barbarian. There is a Vault Tec Big Guns Bobblehead in the basement of the CO Quarters.

History
Not much is known about Fort Constantine, except that Allistair Tenpenny hired 5 mercenaries — Mister Crowley, Dave, Dukov, Jeff Strayer, and Tara — to retrieve a weapon from the Fort. It is unknown what weapon Tenpenny was after, but it was possibly the "Fat Man" or the T-51b Power Armor. In the Bunker, Tara was killed by a group of feral ghouls and Crowley was locked in the same room; this was where he supposedly later found the T-51b Power Armor, leading to his obsession over it. The rest of the group, knowing Tara was dead and thinking Crowley was dead as well, went their separate ways.

Years later, Mr. Crowley, now living in Underworld (it is unknown how he escaped Fort Constantine), wants the Lone Wanderer to find all the other surviving mercs (Except for Jeff Strayer, whose son, Ted Strayer, holds the key required by Crowley) and shoot them in the head, then return the keys.

ICBM (Intercontinental Ballistic Missile)
The CO Quarters contain the Fort Constantine Launch Codes stored in a small safe in the cellar next to the Big Guns Bobblehead. These can be used to launch the ICBM in the Fort Constantine Launch Control Terminal in the Launch Control Bunker. After attempting to launch the ICBM, the launch terminal reports an error and mentions that the missile's tracking system is damaged and the navigation data is corrupted.

Appearances
Fort Constantine only appears in Fallout 3.

Bugs

 * It is possible to find a bugged Enclave soldier in the vicinity of Fort Constantine, generally located between the Fort and the Outcast Shack. This particular soldier appears and respawns well before the Enclave arrive in-game, regardless of whether Broken Steel is installed.
 * The Guns and Bullets skill book located in the CO Quarters on the Queen Sized Bed seems to have a significant clipping issue for players. It is located on the bed by the back entrance, but it isn't always visible. PC users can acquire the book using the 'tcl' no-clip console command. Console users may be able to retrieve it by re-loading a save inside the CO Quarters until it appears and is obtainable.
 * The area outside the main building is highly glitched. Followers glitch underground and die when exiting Bomb Storage. Reloading any save including autosaves from after the moment you open the door causes the follower to instantly die again.
 * After fast-traveling to Fort Constantine, you will almost certainly be attacked by the robots found there. Charon might get stuck constantly entering and exiting the Personnel Offices in an attempt to reach the robots found on the roof of said building.
 * In some cases, upon entering the room with the T-51b Power Armor in it, the T-51b Helmet might be on the ground and/or the T-51b Power Armor might be glitching around inside of the statis chamber. This will not effect anything other than that.
