Miscellaneous Quests

These quests are various different quests that you can do which are optional.

The Lost Patrol

To begin this quest, speak to Captain Kell safer doing the Show No Mercy quest. Begin by tracking down the fallen recon team members. Go northeast to get to Med-Tek research and try to get near to the distress signal. When the strength is at 100%, you will be near a research building. The house south of it has the remains of Knight Varham.

Southeast side of the National Guard Training Yard has the second guy followed by the Revere Satellite Array which has the third guy. All you need to do is to use the radio to locate the stress signal.

The third guy will give you Recon Bunker Access Code 429A which you can use to enter the Theta bunker at the north side of the map. Here, you can kill either Paldin Brandis or simply end the conversation in a peaceful manner.

Duty or Dishonor

This quest is available once you have done The Lost Patrol and Show No Mercy quests. Captain Kells will assign you to question the Airport staff about some missing supplies. First, talk to Knight-Sergeant Gavil and talk to everyone that he mentions to you. After that, talk to Gavil once again before heading to Lucia’s locker.

When you find the tape in Lucia’s locker, confront Lucia with what you found and then tail Clarke to the ruins below the airport. Eventually, you will be able to talk to Clarke and convince him to lower his weapon if you have a high enough charisma. Either you can kill him or you can spare him.

If you kill him, the matter will be solved. If you decide to spare him then there are two different options that you can take. One is to report his crime and have him sent to the police station. The other is to not report his crime and lie to Captain Kells about the whole matter.

A Loose End

Captain Kells give this quest to you. It is only available after you have completed Duty or Dishonor and you have begun Liberty Reprimed. The objective of this quest is for you to kill Virgil because Captain Kells seems to have one reason or the other for him being dead.

If you had destroyed the Institute without granting Virgil the serum, he will already want to kill you once he sees you. This means that you have to kill him as soon as you see him or you will be dead.

However, if you had given him the Serum at an earlier point in the story, then you can decide to either kill him or let him go. If you decide to let him go, it would mean that you have to lie to Captain Kells when providing him your report. The quest will be complete once you hand in your report to Captain Kells.
