Voice 4: 'A shining example.' That's what it called us. Voice 1: Are we really gonna do this? It's open. On it is a security recording of the vault entrance. Nearby is a terminal, one of Fallout's famous green-flickering lore boxes. Through the main door, on the floor of a large entry room are four skeletons huddled together.
The vaults were designed to keep nuclear fallout out and happy dwellers in. Most of the vaults you encounter throughout the Fallout games are locked shut, which makes sense. Vault 11 is unusual in that when you first arrive its main door, the one with the number 11 on it, the one would normally hiss and creak before pulling back and rolling sideways, is open. The Brotherhood said nothing about the horrors inside. The Brotherhood of Steel have sent us here to find a differential pressure controller, one of the parts needed to repair their faulty air filtration system. It is rotting wood and nails and spider webs clinging on to existence like the people of Fallout's post-apocalyptic Mojave Wasteland. Nestled in the mountains, the door that leads to Vault 11 is the kind you see hammered onto a shack.
