All Vaults In Fallout 4 Locations And Exploration Guide

Exploring the underground bunkers scattered across the Commonwealth is one of the most compelling aspects of Fallout 4. Built by Vault-Tec, these subterranean facilities were advertised as safe havens from nuclear annihilation, but most hid sinister social and psychological experiments. Uncovering every Vault requires navigating dangerous ruins, solving local quests, and overcoming hostile inhabitants.

Vault 111 and Vault 114 Exploration

Vault 111 serves as the starting point of your journey, located just northwest of Sanctuary Hills. While initially explored during the prologue, returning later with higher lockpicking skills allows you to claim the powerful Cryolator weapon. This facility housed cryogenic chambers meant to observe the long-term effects of suspended animation on unsuspecting citizens.

Located beneath Park Street Station in downtown Boston, Vault 114 plays a central role in rescuing Nick Valentine. Originally constructed to test the reactions of high-society politicians forced to live in squalor, it now serves as a hideout for Triggermen mobsters. Exploring every corridor reveals intriguing audio logs and unique bobbleheads hidden within the living quarters.

Vault 75 and Vault 95 Locations

Situated directly under Malden Middle School, Vault 75 was designed under the pretense of protecting local school children during an attack. In reality, scientists harvested genetic material from youngsters to refine human traits, liquidating adults immediately upon entry. Navigating this facility involves fighting through well-equipped Gunners who now use the bunker as a base.

Vault 95 is hidden in the southwestern edge of the Glowing Sea area, packed with heavy opposition from Gunners and assaultrons. Built as a rehabilitation facility for individuals suffering from substance addiction, Vault-Tec intentionally introduced a hidden stash of drugs to observe their collapse. Finding this location is critical for players who want to assist certain companions with their personal recovery quests.

Vault 81 and Additional Expansions

Located west of Chestnut Hill Reservoir, Vault 81 is one of the few functional underground communities remaining in the wasteland. Unlike other facilities, its overseer halted the planned medical experiments, allowing a peaceful society to flourish inside. Trading with residents unlocks unique gear, while a secret wing contains the Curie companion and special medical bobbleheads.

For players with expansion content, Vault 88 offers a unique opportunity located near Quincy Quarries. Part of the Vault-Tec Workshop add-on, this massive subterranean cavern allows you to take on the role of Overseer and construct a custom bunker. Gathering resources and experimenting on willing dwellers gives you total creative control over subterranean life.

Essential Preparation for Vault Scavenging

Delving into these underground structures requires adequate preparation, including bringing plenty of RadAway and hacking tools. Many Vault doors remain sealed behind master-level terminals or security keycards held by elite enemies. Bringing along a strong companion ensures you can manage heavy loot loads while unearthing historical secrets.
