2015's Fallout 4 has more quests, outfits, and weapons than the average game. In fact, most players will most likely never see all of the content in the game. Much like Fallout 3 and Fallout New Vegas, Fallout 4 is has a lot of cut content that the player might not have known about. Some of this content is easily accessible, while some is virtually unknown.
Some cut content added special clothes for certain characters, while some of the cut content could have changed the story of Fallout 4. By looking at Fallout 4 art books and through Twitter and Reddit posts by designers, players are able to get an idea of some of that cut content.
10 Vault 101 Jumpsuit
Fans of Fallout 4 will recognize this as the vault the Lone Wanderer came out of. What this jumpsuit is doing in the Commonwealth is unknown, but it could have meant a familiar face might have appeared.
It is known that a member of the Institute can be found in Rivet City in Fallout 3 and MacCready made it to Boston, making it possible for a vault dweller to get to Boston in the 10 years between the games. Whether it was the Lone Wanderer themselves or one of the residents, it would have been a welcomed surprise.
9 Able To Become Elder
When it is found out Paladin Danse is a synth, there are three options the player can pursue. There used to be another option, where the player could challenge Maxson to a duel and become Elder of the Brotherhood of Steel. It would be odd for a person who had been in the group for less than a few months to become the leader.
The duel would have been to the death, meaning Arthur Maxson would have been killed off. On the bright side, his outfit could be looted for the player to wear.
8 More Vaults Were Planned
As seen in the concept art, there were more vaults that were supposed to be in Fallout 4. Vault 117, Vault 113, and Vault 17 are missing from the game. Interestingly enough, Vault 17 is mentioned as the vault Fallout New Vegas companion Lily Bowen came from.
Vault 117 became Vault 81 in the released game, but it would have been interesting to have a few more vaults located around Boston. It would have been especially interesting to see how Vault 17 would have made an appearance.
7 More La Coiffe Magazines
In Fallout 4, only two La Coiffe magazines can be found. Three other magazines were cut, including one that would have added a hairstyle for a male protagonist. While it is unknown why the other versions were cut, it would have been interesting to have more hair options.
The only named cut hairstyle is the Anchorage, which would have given the player an army style haircut. From the covers of the other two hairstyles, they do not look like they would be as extreme as the Megaton and Hornet styles.
6 MS08 Quest
What is interesting is nothing can be found about this quest except for an aged male Sole Survivor, named Game Master 3000 Mk II. It could be assumed this was a quest related to the Institute, or that the male Sole Survivor could have been unfrozen somehow.
It is interesting to find a cut quest, but it is especially interesting to find a quest that only offers one NPC, who happens to be the protagonist. As of now, there is no information about what the quest would have been.
5 Centaurs
The (somewhat) lovable creatures were going to make a return to Fallout 4. Instead of the mutant hounds, Super Mutants were going to keep their original sidekicks. The creatures also went through a design change.
From the concept art, the Centaur would have three heads attached to it and be more dog-like. Centaurs in previous games crawl around on their stomachs, but the concept art shows the centaurs walking on four legs.
4 May-Pole
The May-Pole was supposed to be a unique Glowing One that would have stood at 300 feet tall. The creature would have been surrounded by a horde of feral ghouls, which could be healed by the May-Pole. The creature would have been a terrifying sight to run across.
The designer, Jonah Lobe, said on a Reddit post that this was a passion project and he was inspired by Shadow of the Colossus. Sadly, the May-Pole would have created technical issues, so it was never added.
3 Compound Bow
The compound bow was supposed to be added to the Far Harbor DLC, but it was cut. Fans of Skyrim would have been able to carry on the tradition of being an archer. The bow most likely would have been a good way to take out enemies without alerting them to where you were.
The compound bow did make an appearance in Fallout 76 instead. Originally it was cut from the new game, but it was added in the Wastelanders update.
2 Extra Brotherhood Of Steel Uniforms
The uniforms a few of the Brotherhood of Steel characters would have worn were supposed to be different. Captain Kells was going to wear a uniform that looked similar to Piper's outfit and Elder Maxson was to wear a cape. There was also plans for a Brotherhood of Steel lab coat, most likely being what scientists would have worn.
Despite these items being cut, Captain Kells and Elder Maxson got their own unique outfits. Maxson's outfit might not have been as popular if it only added a cape.
1 Radstorks
Radstorks are enemies that were supposed to be found in Fallout 4. Something about massive birds attacking the player would have been an amusing sight. While it is unknown if they would have flown, it would be interesting to have a bird foe.
In the chance radstorks could have flown, it would have been intriguing to see if the player could be ambushed by a flock. Hopefully, these creatures will appear in a future game.
