Trouble on the Homefront

 is a Fallout 3 quest. It is also an Xbox 360 and PC achievement.

Objectives and walkthrough
You will get this quest after the second round at the Jefferson Memorial. You will get the Vault 101 distress signal, it is a message from Amata asking you to return to Vault 101 to help stop her father. You get back to the Vault to see it in shambles, and divided into two factions, the rebels and the Overseer's people.

Amata will ask you to stop her father from sealing the vault forever. She will ask you not to kill him but you will probably end up killing him anyway. Go and talk with him and you have a few options. Kill the Overseer, kill all the rebels or just leave without doing anything.

If you kill the overseer Amata will become the Overseer. No matter how you talk to her she will ask you to leave forever.

If you kill all the rebels, the same thing will happen. You will be banished.

I personally killed the Overseer because I didn't want to kill Amata.
