Their first appearance in the franchise was in
Fallout 2, in which the group is attempting to "purify" the wasteland by introducing a modified form of the FEV into the water supply, effectively enacting a genocide against all people with traces of
radiation exposure, including human wastelanders as well as
ghouls and Super Mutants. Following
ZeniMax Media's acquisition of the Fallout IP, the Enclave reappeared in
Fallout 3, portrayed as a separate branch operating out of
Washington, D.C. This branch has a similar goal, to inject an in-progress
water purifier with a modified form of FEV to kill all wastelanders with traces of radiation exposure.
Fallout: New Vegas (2010), developed by a team at
Obsidian that overlapped with the staff of
Fallout 2, featured the Enclave as a minor faction called the remnants, a group of six former members of the western branch featured in
Fallout 2. They can be recruited to fight at the final stage of the game, the Battle of Hoover Dam, for either the
New California Republic (NCR) or Caesar's Legion. A group of
modders greatly expanded on the Enclave in 2014, making them a playable faction. As part of
Fallout 4 (2015)'s
next-gen update released in 2024, a free
Creation Club addon featuring the east coast Enclave was released. This features a small questline with Enclave members as enemies, described in-game as remnants. These enemies are unrelated to
Fallout: New Vegas' Enclave remnants, instead originating from
Fallout 3's Enclave. They later appeared in
Fallout 76 (2018), taking place 59 years before the original
Fallout (1997). They appear as a defunct branch operating out of the
Appalachian wasteland entirely by robots, including its leader, the computer MODUS. They are in an inoperable state until the player first encounters them, where they are tasked to complete MODUS' mission.
TV series In
Amazon MGM Studios'
Fallout (2024), a
live action series taking place in the
Fallout universe, features the Enclave. In the
first season, an Enclave scientist, Dr. Siggi Wilzig (
Michael Emerson), escapes from an Enclave facility of unknown allegiance. Wilzig carries with him the
cold fusion technology, which he intends to give to Lee Moldaver (
Sarita Choudhury) of the
New California Republic (NCR). In Filly, Wilzig encounters Lucy Maclean (
Ella Purnell), and they flee together after a battle. Severely wounded, Wilzig tells Lucy to cut off his head, which she does. In the
second season, in 2077, Wilzig reminds Barb Cooper (
Frances Turner) that she cannot back down on the bomb launch or she will be replaced, as the
nuclear war is inevitable.
Cooper Howard (
Walton Goggins), hoping to avert nuclear war, hands over cold fusion to the President of the United States (
Clancy Brown), secretly part of the Enclave. In 2296, Howard, seriously wounded, is saved by a Super Mutant (
Ron Perlman) who proposes that he join the war that his race will wage against the Enclave, but Howard declines his offer and the Super Mutant leaves him elsewhere. Hank MacLean (
Kyle MacLachlan) confesses to his daughter Lucy that he has been working for the Enclave all this time and that the Wasteland is the true experiment. At
Vault-Tec's Vault 32, Overseer Stephanie Harper (Annabel O'Hagan), contacts the Enclave to initiate Phase 2. ==Reception==
