Use the Relay to Reach the Airport

Go to the central elevator of the Institute to get into the relay. The relay will teleport you to Boston Airport where the Brotherhood is.

Infiltrate the Terminal

After arriving at the airport, you will need to go to the terminal which is marked with an objective marker.

Many Brotherhood members will attack you upon your arrival. Make sure that you are fully equipped with strong weapons and armor, as well as bringing food to survive the Brotherhood's wrath.

Destroy Brotherhood Generators

Upon reaching the terminal, your next mission is to destroy 3 Brotherhood generators. They are scattered around the base and will be guarded by Brotherhood members so be careful when dealing with them.

Reach Liberty Prime

After destroying the generators, synths will come to your aid as you try to go towards Liberty Prime's head.

Defend the Synth Hacking Liberty Prime

Once you reach the top of Liberty Prime, you will need to defend the Synth that is uploading the virus to hack Liberty Prime. During this section, many Brotherhood members will attempt to stop the synth including Elder Maxson who is attacking via his vertibird.

It is recommended to stay close to the Synth instead of going down Liberty Prime in order to properly defend it. Once the hacking progress reaches 100%, you will be tasked to evacuate the area.

It is also possible that you'll fight Elder Maxson on the ground if his vertibird gets destroyed. You can obtain his exclusive weapon, Final Judgement.
