“
Look around you! Look at the scorched earth and the bones that litter the wasteland. Millions... perhaps even billions, died because science outpaced man's restraint! They called it a "new frontier" and "pushing the envelope," completely disregarding the repercussions. Can't you see the same thing is happening again?

”— Elder Maxson
The **War of the Commonwealth** is a large conflict that occurs in 2287 between the Institute, the Railroad, the Brotherhood of Steel, and potentially the Commonwealth Minutemen.

## Prelude

After years of development, the Institute succeeded in the creation of generation 3 synths, robots completely identical to humans, in the late 2220s. In the years to follow, the Institute began sending these synths out to infiltrate the Commonwealth, whether simply given them false identities or by "replacing" wastelanders with synth copies of them. The existence of these synths became known to the people of the Commonwealth in events such as the "Broken Mask" event in 2229, where a synth began shooting people in Diamond City.

Due to the Institute's belief that synths are no more than tools, an organization known as the Railroad was founded. Believing synths to be sentient, the railroad started finding and hiding away synths. The Institute, seeing the Railroad as an annoyance, launched attacks whenever possible, such as the Railroad Safehouse Raids.

In 2287, a Brotherhood of Steel recon squad detected high energy readings coming from the Institute, leaving Elder Maxson no choice but to personally investigate and bring in the Prydwen, setting up camp at the ruins of the Boston Airport, and began to consolidate his forces. Considering synths to be abominations and a clear attempt to tamper with humanity, the Brotherhood begins investigating the Institute in preparation to destroy them.

Even though the Railroad has been in conflict with the Institute for sometime, the arrival of the Brotherhood poses a serious problem for them in the long run; they fear the Brotherhood may target safehouses where the Railroad is trying to get defecting synths out of the Commonwealth in order to achieve their goal of wiping out all synths. Conversely, the Brotherhood has dealt with the Railroad in the Capital Wasteland, and knows they may pose a threat to their operations in the Commonwealth, as they clearly ideologically oppose the Brotherhood's goals. Thus, while their primary enemy is the Institute, they both feel peace either is not a strategical option or will bring more problems than solutions. Thus, at the very least running each other out of the Commonwealth will bring their vision of "peace" quicker.

While the tensions build, the Minutemen can build and potentially become a major player in the war. While no faction but the Institute is openly hostile to them, the Brotherhood and the Railroad begrudgingly allow them to grow in power and strength, and lead a peaceful, but tense, coexistence. If the Minutemen retake the Castle, all three other factions notice immeadiately and a four-way open warfare nearly breaks out between them, but the Sole Survivor's connections ease the nerves of their leaders.

## War

The arrival of the Prydwen led to increased hostilities throughout the Commonwealth, including the Brotherhood investigating the C.I.T. ruins and encounters with synths. The Institute also began stepping up efforts to combat the Railroad, such as taking out a route used for smuggling synths out of the region. The Railroad both continued to fight off the Institute while planning on how to deal with the Brotherhood of Steel's arrival.

At one point, the pre-War individual known as the Sole Survivor, who had been frozen in a cryopod for over two hundred ten years, became involved in the conflict. Some time during their Vault's cryogenic stasis, Kellogg and two Institute members broke into Vault 111, killed the Sole Survivor's spouse and kidnapped their son, Shaun. Searching for Shaun, they eventually confront and, after learning that Shaun is being held by the Institute, kill Kellogg. While searching for a way to gain access to the Institute, the Sole Survivor begins interacting with the other factions, including possibly joining the Brotherhood of Steel, becoming an agent of the Railroad, rebuilding the Commonwealth Minutemen with Preston Garvey, or possibly some combination of the three.

Whatever the Survivor decides, they eventually get into the Institute, and it is revealed their son is, in fact the administrator and director of the Institute, Father. From this point on, the Sole Survivor decides who to take sides with.

With the Sole Survivor getting unlimited access to the Institute, they become an important asset to the Brotherhood of Steel, who wish for information from their computer network, and the Railroad, who request the Sole Survivor make contact with an inside agent, Patriot. If the Sole Survivor chooses to help these factions, conflicts between them will begin to escalate, such as the Institute attacking the Railroad's interests in Bunker Hill, resulting in a potential three-way battle between the Institute, Railroad, and Brotherhood of Steel. The Institute also may assault and wipe out one of the Railroad's safehouses, Ticonderoga.

Both the Brotherhood and the Institute require a large amount of energy to either power Liberty Prime or provide a permanent power source for their underground laboratory. Whoever the Sole Survivor decides to help, they head to the Mass Fusion Building and helps either Proctor Ingram or Allie Filmore secure the huge nuclear reactor, battling opposing forces along the way. After securing the reactor, they are prepared to finally take the fight to the enemy.

If they sided with the Brotherhood, they will wipe out the Railroad and use the newly repaired Liberty Prime to blast a hole in the ruins of the C.I.T. Ruins and destroy the Institute from within using their decaying nuclear reactor.

If they sided with the Institute they will wipe out the Railroad and then launch an attack on Boston airport, where they will hack Liberty Prime to recognize the Prydwen as a "Communist" vessel and destroy it.

If they sided with the Railroad, they will infiltrate the Prydwen using a Vertibird, then set three blast charges in the main deck of the ship. After removing the Brotherhood as a threat, they will infiltrate the Institute using their inside contact (Z1-14), and destroy the facility using their nuclear reactor.

Finally, if the Sole Survivor angers the Institute, they can have the Minutemen wage war against them. While this will result in the Institute attacking the Castle, their members will be able to sneak into the Institute and destroy it from within using their nuclear reactor.

## Aftermath

Whomever the Sole Survivor decides to side with, their presence will become the dominant force in the Commonwealth. Diamond City will also be controlled by the ruling faction, with their respective flags being displayed over the city. For example, siding with the Brotherhood will place a Knight browsing the stores and a Senior Scribe in front of the noodle shop. Conversely, siding with the Institute will place two Generation 1 synths in Diamond City, idly using work benches and browsing shops. Additionally, checkpoints will be established across the Commonwealth, which the Sole Survivor has the option of assisting in its defense.

A conflict can also start between the Minutemen and Brotherhood of Steel, with the Brotherhood attacking the Castle and settlements after the Minutemen take down the Prydwen with their artillery.
