Destruction of Control Station Enclave

The destruction of Control Station ENCLAVE was the nuclear devastation of the Enclave's oil rig on the Pacific Ocean in the year 2242.

Prelude
The Chosen One boarded the PMV Valdez after recovering fuel sources to power the tanker, and rode the ship across the Pacific and docked in the oil rig. After the Enclave invaded Arroyo and Vault 13, the inhabitants of the two locations were imprisoned on the oil rig.

Destruction
After sneaking through the entrance sector of the rig, the Chosen One spoke to members of his tribe in their cells. His mother informed him that it was possible to overload the facility's nuclear reactor, causing a meltdown. The Chosen One went through the presidential offices, and could have confronted President Dick Richardson. After reaching the rig's reactor, the Chosen One would have found a way to destroy or shut down the reactor (shutting down the reactor too quickly will cause a meltdown).

Afterwards, the Chosen One went for the rig's entrance to leave before the rig exploded. However, he was faced by Frank Horrigan and the Enclave Control Company, led by Granite. The Chosen One convinced Granite and his team to abandon the Secret Service and join him, and fight by his side against Horrigan. After defeating Horrigan, the Chosen One and the ECC escaped the oil rig in time. Upon their departure, the rig was obliterated by the reactor, releasing a ginormous megaton-sized mushroom cloud.

Aftermath
The Enclave's plan to poison the Earth's jetstreams with Forced Evolutionary Virus, committing the genocide of post-War humanity, was abolished. The Enclave suffered immense losses with the destruction of the oil rig and was thrown into disarray. All personnel that managed to flee the rig in VB-02 Vertibirds relocated to various locales throughout the United States, with the main force heading for the Capital Wasteland under the command of Autumn Senior, by order of the new self-proclaimed President John Henry Eden.

The truth behind the incident never came to light, however, and the Chosen One and his allies' stories of their actions on the rig were blown off by the masses as myth and legend. Not even the Enclave discovered the events that occurred on the rig and Navarro sometime after, considering it to be an 'internal sabotage'.

Appearances
The destruction of Control Station ENCLAVE appears only in Fallout 2, and is mentioned in Fallout: New Vegas and the Fallout Bible.
