Vault 87

Vault 87 is one of the Vault-Tec Vaults, located in the western edge of the Capital Wasteland. As part of the Vault Experiment, experimentation on a Forced Evolutionary Virus (FEV) strain different from the one in Mariposa was conducted on its inhabitants. The vault is full of super mutants and centaurs. By reading information on the computers, it becomes clear that eventually some Mutants escaped and killed their creators. Various rooms have been sealed from the inside using tables as barricades.

Fawkes is found after fighting through various floors. She remains sealed in a test chamber and appears to have been locked in this room for almost 200 years. However, the main entrance is flooded with radiation that increases exponentially closer to the entrance. Entrance is possible by traveling through Little Lamplight after Mayor MacCready opens the gate for you. Another possible access point is to ask Joseph to turn on the computer terminal and hacking the computer. These dialogue/solution options are not present in the game until after Vault 87 is referred to in the main quest Picking Up The Trail.

Entering through the Reactor room, there is a copy of Nikola Tesla and You in the nearby room that glows red, inside the box next to the mannequin.

An unused Garden of Eden Creation Kit can be found here.

Above ground, the radiation at the entrance to Vault 87 seems to peak at 3,695 rad/sec. By using the 'toggle collision' cheat, the radiation peaks at 4,650 rad/sec. Cause (obtained with GECK): "I'm quite sad to report that due to a direct hit from what I presume to be a nuclear weapon on the entry area of Vault 87, we will be unable to provide the Scouting Reports as outlined in Vault-Tec's Operations Manual. The main door to Vault 87 is damaged beyond repair and we are detecting extremely high levels of lethal radiation outside and in the entry tunnel." (would be in the Overseer's terminal)

One of the Engineering Logs on a terminal inside the vault talks about problems venting large amounts of radiation from the GECK chamber.

''It is not possible to enter from above ground, even if you would survive the radiation, the game doesn't let you in. ("[INACCESSIBLE]".)'' A few dead scientists are outside the entrance, but no really interesting items.

Notable Loot

 * A copy of Nikola Tesla and You can be found in a wooden box at the feet of a mannequin in the southwestern-most dead end tunnel of the Reactor Chamber. (From the Murder Pass entrance, turn left and go downstairs, turn left again, then through the door at the end of the corridor.)
 * A copy of Pugilism Illustrated is on a shelf in the storage room on the catwalk level of the living quarters. To find the storage room, travel south from the catwalk strewn with Gore Bags and look on the south wall between the two doorways.
 * A Nuka-Cola Quantum can also be found in the aforementioned storage room on top of the southwest shelf.
 * A safe in the west wall of the storage room with an "average" lock may contain a Stealth Boy(might be random).
