Trouble on the Homefront

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

Objectives and walkthrough
This quest will be activated after the second quest at the Jefferson Memorial. You will pick up the Vault 101 distress signal on your radio the next time you wander near the Vault (Megaton is close enough). It is a message from Amata asking you to return to Vault 101 to help stop her father.

On returning to the vault you will find it has split into two factions. One faction led by Amata wants to open the Vault and interact with the outside world. The other led by the Overseer wants to keep the vault closed permanently, in accordance with its mission.

Once you meet Amata, she will will ask you to stop her father from sealing the vault forever. She will also ask you not to kill him.

Go and talk to the Overseer. Be aware that if you encounter Officer Wilkins, for instance by entering the red security area on the upper floor, he will try to kill you. You have a few options:

1) Kill the Overseer. 2)  Kill all of the rebels. 3) Leave without doing anything (this decision, if you make it, is permanent). 4)  Persuade the Overseer to open the vault with your speech skill. 5) Persuade Amata to stay in the vault with your speech skill. 6)  Go to the jail and use the computer there to find out about Security's plans to raid and kill the rebels. The computer is locked; you can hack it with sufficient science skill, or you might be able to find the password simply by searching the lockers in the room, or else you can find it on Officer Wilkins. Then, talk to the Overseer and tell him about Security's plans. This will have the same effect as if you persuaded him with your speech skill.

If you kill or persuade the Overseer, Amata will become the new Overseer. Regardless of how you solve the problem (or decide not to bother), you will be asked to leave the Vault.

Interestingly enough, if you end the situation amicably, Amata's speech to the PC regarding the "tough decision" of asking them to leave the vault is strikingly similar to the speech given to the PC of Fallout 1 at the end of that game.

Depending on how you resolved the issue, you may be awarded the Modified Utility Jumpsuit.
