The Fallout series features some amazing quests. It's the kind of franchise where the side quests often outshine the main storyline. Not because the main quests are bad, but because it's the side quests that really let the player dive into Fallout's unique style of world-building.

9 Best Open-World Post-Apocalyptic Games, Ranked

Many open-world games set themselves after some sort of apocalyptic event. These titles, however, are easily the best ones available.

The world of Fallout is dark and full of dangers, but it's also hilarious. This sense of humor often offsets some of the darker aspects of the franchise, but not always. Each game in the series features multiple quests that are so creepy and disturbing they serve to remind the player how grim life in the Wasteland really is. These Fallout quests haunt the player long after they've been completed.

9 Kid In A Fridge

Indiana Jones Was Right

Fallout 4 a ghoul hiding in a fridge

Fallout 4 has a lot of hidden quests and Kid in a Fridge is easily one of the best. If players travel north of Neponset Park, they'll discover a nondescript fridge with strange noises coming from it. Open up that fridge and the player will find Billy, a ghoul child who has been stuck in there since the bombs fell.

Every franchise is going to have some great quests as well as annoying ones, and these are the most frustrating quests in Fallout

That means poor old Billy has been trapped, and conscious, inside a confined space for over 200 years. That's pretty horrific if you stop and think about it. Billy just wants to go home, but if the Sole Survivor is feeling particularly villainous, he can sell the child to nearby Gunner, Bullet. If the player does the right thing, he can reunite Billy with his parents, conversely making this one of Fallout's most memorable feel-good quests.

8 Devil's Due

Deathclaws Are The Worst

The basement from the Devil's due scary quest

The Fallout games can be plenty scary at times, but they can rarely be described as actual horror games. The Devil's Due, however, is proof that the developers absolutely could make a Fallout horror game if they wanted to.

This quest is set in Salem's Museum of Witchcraft. Players enter through the basement and soon find the museum was the site of a massacre. There are limbs everywhere, unsettling dioramas, and jump scares galore. The worst thing about the quest though is the fact you can hear one of Fallout 4's strongest enemies prowling about upstairs. It's all very unsettling and deeply disturbing. The only reason this quest doesn't feature higher is because, for the most part, the player is just along for the ride. They don't have to make any serious decisions and by this point in the game, they've probably already faced their fair share of Deathclaws.

7 Tenpenny Tower

No Good Options

The best Fallout quests usually force the player to make tough decisions, and Tenpenny Tower is a great example of this. The rich and privileged residents of Fallout 3's Tenpenny Tower have a problem - there's a band of nearby ghouls who want to move in with them. These ghouls also have a problem - the wasteland is harsh and unforgiving, and they need somewhere safe to live.

14 Best Side Quests In Fallout 3, Ranked

Fallout 3 has plenty of side quests to keep players busy between missions, and these are the best the game has to offer.

The player has three options: side with the stuck-up residents and kill the ghouls, side with the ghouls and evict the residents, or try and reason with both sides for a happy ending. It's this "happy ending" option that makes the quest so disturbing. The Lone Wanderer can convince the Tower's most reasonable residents to let the ghouls move in, supposedly so that man and ghoul can live in harmony. Sadly, if the player returns a short time later, they'll find the ghouls massacred the original residents anyway. The only thing that softens the blow is knowing at least some of the residents had it coming.

6 Fallout 4's Main Quest

A Series Of Unfortunate Events

Fallout Seans

Fallout 4's main quest isn't all that popular with a lot of Fallout fans compared to those of Fallout 3 and Fallout: New Vegas but in a lot of ways it's underrated. In particular, it puts the Lone Survivor through the meat grinder and is full of disturbing events.

First, the Lone Survivor sees their entire world being destroyed by nukes. Then they're tricked into entering a cryogenic slumber and wake up just in time to see their spouse murdered and their baby kidnapped. After a long search, the protagonist then discovers that not only is their child, Sean, old and dying - he's also drunk the Institute's Kool-Aid and become its leader. The player can side with their son, or destroy everything he's worked for. It's enough to drive a normal person crazy. Unfortunately, there are so many distractions in the game, this questline becomes incredibly dragged out, ultimately diluting its impact. By the time most players find Sean, they no longer care.

5 Secret of Cabot House

A 400-Year-Old Psychopath

The Secret of Cabot House has it all - a creepy psychopath, alien conspiracies, ancient artifacts, an insane asylum, and tough moral decisions. It's certainly one of Fallout 4's most underrated quests. The quest centers around Lorenzo, who 400 years ago found a strange artifact that gave him superhuman abilities. Sadly, it also drove him insane.

Numerous quests populate the world of Fallout 4, and players can figure out which are consistently tough or easy to complete.

Lorenzo's family didn't have the heart to put him down, so instead they did the "humane" thing and locked him away in an asylum for several hundred years. By the time the Lone Survivor comes along, Lorenzo is well and truly crazy, itching to escape. The player has two choices - either free Lorenzo and allow him to travel the Wasteland experimenting on people or kill him. Chatting with Lorenzo as he explains his warped worldview is disturbing as he can be oddly convincing. Despite his horrific acts, it's also easy to feel sorry for the guy after 400 years of being imprisoned. Whatever choice they make, it's certain to haunt the player, for a short while at least.

4 Democracy Inaction

Classic Vault-Tec

Courier in the Vault 11 projector room

Anyone who has played a Fallout game will be familiar with Vault-Tec and its countless sick experiments. This being said, what the player uncovers during Democracy Inaction is especially messed up. The quest takes place in Fallout: New Vegas' Vault 11, where vault dwellers were made unwitting subjects in a twisted social experiment.

Each year they were forced to elect an Overseer who would then sacrifice themselves so that the rest of the vault could live. By the time the player arrives, everyone is dead and the details of the experiment are found by listening to recordings and reading terminals. When the player reaches the quest's end, they discover the hidden truth- if the inhabitants had banded together and ignored Vault-Tec's instructions, everyone would have been spared. It's a tragic ending and a disturbing look into human psychology and group mentality.

3 Our Little Secret

Creepy Cannibals

Fallout 3 Andale

Fallout 3 has its fair share of disturbing locations, but Andale is easily one of the worst. Our Little Secret is an unmarked quest that begins as soon as the player stumbles into this seemingly idyllic little town and begins talking to the residents. One of them, Old Man Harris, tells the Vault Dweller to stay away.

The best quests aren't always found on a Pip-Boy! Fallout New Vegas has some unmarked quests every player should check out.

It soon becomes clear that something is off about Andale and the player is tasked with finding out what. By snooping around, the player will find out that the people of Andale have survived by eating other wastelanders and committing incest. Whatever the player does, they'll be discovered by the townsfolk. The player can either talk their way out of it and join the cannibals, or become dinner. Everything about Andale is designed to creep the player out but the residents' indifferent attitude to everything they've done is particularly chilling.

2 Pickman's Gift

A Real Artist

fallout-4-pickman-gallery

Fallout 4 has a lot of good side quests, but Pickman's gift is one of the best in the entire franchise. The quest's main location, Pickman's Gallery, just oozes with atmosphere and features a ton of nightmare-inducing imagery.

Either by finding one of his calling cards on a dead reader or by stumbling upon it naturally, the player will eventually find themselves entering Pickman's Gallery. It's a disturbing location overrun by raiders who attack on sight. They're looking for a serial killer who has been picking them off one by one, and they mistake the player for him. The player must fight their way through the artist's grotesque artwork until they find the man himself. Pickman is surprisingly charming and the player can either let him go or kill him. This tough moral quandary and the imagery the player is exposed to throughout make this one of Fallout's most disturbing quests by far.

1 Tranquility Lane

Trapped In A Simulation

Betty Dialogue Fallout 3

What makes Tranquility Lane so disturbing? Pretty much everything about it. For a start, it features one of the best child villains in gaming, Betty, who just happens to be a sadistic scientist in disguise. Upon entering the simulation, the player loses access to all their tools, including the Pip-boy, making this a rare instance in Fallout where the player is left feeling powerless.

There are some truly unusual side quests lurking in the corners of the wasteland.

The quest takes place in Vault 112, where the vault dwellers have spent the last 200 years unwittingly living in a simulation of the pre-war world. It is here the player meets Betty, a seemingly innocent little girl who gives the Vault Dweller a series of increasingly disturbing tasks. The player can either do as Betty (in reality Stanislaus Braun) asks and help her torture her victims or work against her. The longer the player spends on Tranquility Lane, the more disturbing everything gets.
