"Imminent attack. Seek shelter immediately! Imminent attack. Seek shelter-"


Everyone was running chaotically in the corridors, despite the obvious warning. "Silly humans," the Overseer thought to herself as she manages the semi-automatic point defense system of the Vault. The batteries mounted on the top of Vault 121 were designed to destroy incoming missiles. The synth didn't want to repeat the mistake she made with the Enclave, when they first attacked Vault 121.

It only took a fraction of a second for the Overseer to notice the familiar symbol on one of the incoming missiles. The Brotherhood... They must have marked this Vault as a synth hideout. The missiles rained down from the sky; a quick count revealed at least 40. Too many for the synth to handle by herself.

"We are being breached. Everyone head over to the armory. Security to the vault door. NOW!"


A team of Brotherhood of Steel agents, equipped with Stealth Boys, broke into the Overseer's office, quickly disabled her, and took her away. In another part of the vault, taking advantage of the confusion created in the attack, the man in power armor broke into the server room and shut down the main terminal. The eternal humming of machinery stopped and no more voices could be heard over the intercom.

The intruder managed to turn off everything in the Vault, from life support to lighting. Now that the lights were off and the turrets powered down, Vault 121 was exposed. A security team rushed to the server room to deal with the intruder and do whatever they can to restore power. Pistols against power armor... it's not hard to guess the outcome of this fight. The security guards did what they could, but they would all eventually ended up on the floor. Only two guards left. The young man still standing rushes to a locker near the door and pulls out a Fat Man. From the doorway, he looks at his colleague, while loading the mini-nuke in the catapult:

"Prepare for sacrifice," he says.

His buddy nods and closes his eyes. The guard fires...
