Fallout: 9 Worst Vaults To Be Trapped In
Vault-Tec created some truly despicable vaults in the Fallout series, and these would be the worst ones to get trapped in.
While there are literally dozens and dozens of these kinds of areas in the massive world of Fallout 4, the ones on this list are either the most interesting or the least known among fans. If it’s been a while since fans played this great game, they may want to load it up and go check out some of these obscure hidden locations for themselves.
Updated September 11, 2024, by Jake Fillery: Even the most veteran of survivors in Fallout 4's wasteland might not know about a select amount of hidden locations scattered around the remains of a post-war Boston. Fallout 4 harbors some incredible hidden secrets that everyone can discover, but only the brave will come out alive in some aspects. Whether it's a fun easter egg or something sinister, Fallout 4's best-hidden secrets show that fresh life can always come to the irradiated Commonwealth as the Sole Survivor explores.
23 Kid in a Fridge
Location: North of Neponset Park
Stumbling across the wasteland, it's inevitable that the Sole Survivor will find a few broken families. After all, the Sole Survivor's spouse and child are dead and missing. Yet, there is some hope in the Commonwealth, and players might find a secret fridge that has been left to rust for hundreds of years. Inside is the voice of a child, and Billy Peabody can be freed to aid in the return home.
Kid in a Fridge is a wholesome quest unless players are going for a real mean streak since they can actually sell Billy to a slaver. Nevertheless, finding a pre-war ghoul child hiding out in a fridge Indiana Jones-style is rather funny, and nice, since he gets to reunite with his ghoul parents.

22 Garden Terrace
Location: Upper Area of the Financial District on Top of Haymarket Mall
Found in the Financial District, players can stumble upon what once seemed like a lovely terraced garden. With a beautiful fountain laid to rest among dead grass and trees, players can reminisce on pre-war life as they navigate through the Garden Terrace. Yet, that is until a thunderous roar distracts them.
The Garden Terrace offers a unique surprise in the form of an Alpha Deathclaw that scales the building. A nice location burdened by a deadly threat, it's best that players come prepared with power armor and their best weapons for this fight.
21 The Man Himself, Todd Howard
Location: Dugout Inn
A painting that can offer beauty to keen-eyed players is located in a few locations about the Commonwealth, and it depicts none other than Todd Howard riding a horse with a general's attire on. This pose and outfit is directly referencing Napoleon Bonaparte, and those with keen eyes will easily spot that the face isn't that of Napoleon, but of Todd Howard.
Fallout 4: Worst Things The Sole Survivor Can Do
The Sole Survivor can indulge in some truly evil actions that will see the Commonwealth forever changed in Fallout 4.
It's rather comedic to see one of Bethesda Game Studios's most recognizable and influential faces on a painting. It begs the question if Todd Howard even knew it was in the game since its such a subtle piece of art that it may have slipped by.
20 HalluciGen, Inc.
Location: Found Within The Esplanade Neighborhood
- Hostiles: Gunners
HalluciGen, Incorporated was known for manufacturing biochemicals in an attempt to bring non-lethal technology into the world for military use. Yet, nuclear fallout would cease production, killing the workers, and leaving the experimental chemicals unattended, with all of their valuable data and experiments up for grabs by the future generations of the apocalypse.
Thanks to the brash thinking of some Gunners, these chemicals were released into the building, flooding the halls with hallucinogenic and lethal chemicals that made anyone who breathed this gas become a hostile maniac. Venturing into this location is dangerous for its effects, and it's very easy to get lost in the broken hallways and collapsed floors.
19 Hawthorne Residence
Location: In The Upper District Of Diamond City
- Creatures: Cats
The addition of cats in Fallout 4 is an odd but welcoming surprise, and these adorably furry friends can be found scattered across the wasteland, usually keeping their distance from players and other humans that might want to pet them or go pstpstpst. Nevertheless, if players want to see a cat overload, then picklock the Hawthorne Residence in Diamond City.
Upon entering this building, players will find an abundance of cats, just relaxing here like it's been their property for years. They lounge on the red couches, clean themselves on the floor, and simply laze around as the adorable felines that they are.
18 Vault 75
Location: Found Underneath The Malden Middle School
- Creatures: Synths
There is nothing creepier in Fallout 4 than uncovering a new vault and discovering the twisted Vaul-Tec experiments within. The same is once again said for Vault 75, a secret vault underneath a school, where players will not only have to deal with hostile synths, but also the creepy backstory, uncovered through careful exploration of the Vault, and reading the lore logs of what happened here.
The Vault was all about separating children from their families, having the adults executed to simply raise the youth in a post-war Vault. These children were taught of the horrors of the world, and trained in discipline and strength to survive in the wasteland. It's a creepy location, and the memories linger within.
17 Ted Williams’ Seat In Fenway Park
Location: Aim At The Bleachers In Diamond City
- Ted Williams Easter Egg
This one is more of a history lesson than anything else, but it's a great secret that players can find in Fallout 4's Diamond City. Boston pride is everywhere in Fallout 4, and Fenway Park within Diamond City is just one of the many notable editions. However, one such edition is not available to players by the naked eye, and they will need a sniper or a weapon with a scope to zoom in on the seats of the Fenway Park stadium for a special easter egg.
Fallout 4: 10 Things You Didn’t Know About Diamond City
Fallout 4's Diamond City, located in an approximation of Boston's Fenway Park, holds quite a few unique secrets that most players will miss.
In the distance, players can find a lone red seat among the green seats. This is a real-life thing in Fenway Park, and it's known as Ted Williams' seat, the iconic baseball player who hit the longest home run of the stadium's history, measuring 502 feet, immortalized in real life and again in the video game world.
16 Captain Zao's Yangtze Submarine
Location: South of Boston Airport, Northeast of Four Leaf Fishpacking Plant
- Here There Be Monsters quest
When the Sole Survivor takes the plunge and enters the waters of the Boston Harbor, they may just find a malfunctioning Chinese submarine, holding on board the ghoul crew of Captain Zao. Players can explore this strange relic of the pre-war, and it really is their only evidence of life outside of America in the Fallout universe, as both the vessel and the people inside are from China, causing tension between the Sole Survivor, a pre-war American, and Zao, a ghoul from China, also pre-war.
The submarine is worth exploring for its history, but if valued lessons are not to the interest of players, then they can still explore the vessel and complete its quests to obtain some unique rewards, like Zao's sword, and the submariner outfit worn by Zao. It all depends on how they want their diplomatic relations to go with Zao in a post-war world.
15 Spectacle Island
Location: Coast Southeast of Boston
- Creatures: Mirelurks
Once home to an eccentric billionaire who built himself a mansion on the private island, Spectacle Island is located off the coast of Boston near Warwick homestead. The island is one of the sites in Fallout 4 that can be claimed as a settlement, but players will have to put some work into it as it's relatively well-hidden and harder to access.
To unlock the settlement and claim their loot, players will have to make their way through highly irradiated water (which can kill the player), and then beat a Mirelurk queen and Mirelurk hunters in an intense battle.
14 Handy Eats
Location: General Atomics Galleria
- NPCs: Cook Handy, Waitron
Handy Eats is about as close as Fallout 4 gets to a classic American diner, with a twist (of course). Located in the General Atomics Galleria, the unmarked Handy Eats is a diner where the staff is made up entirely of robots and the customers are old skeletons.
The most notable part of this diner is definitely the robot waiters and cook, but players will also be able to get the fishing tournament ad loot. Be warned, it is not recommended to eat here.
