Description (written by the developer; not a statement by this register)
Welcome to Vault 81, a remnant of a safer past in a harsh and unforgiving wasteland. Once the pinnacle of security, this Vault is now nearly dysfunctional, its walls collapsing and its systems failing. But within these ruined corridors lies the chance for survival and discovery.
