The Elizabeth Protocol

The Elizabeth Protocol was an emergency measure to be carried out at the Chalet in case of a failure or breach of containment with Project Noah. Built into the main building was a small, half a kiloton nuclear device, just powerful enough to completely destroy the facility, including the underground levels.

When the virals escaped, everyone in authority was killed quickly and no one was able to set off the self-destruct before Zero and the Twelve reached the surface. Jonas Lear did escape, rescuing Sister Lacey, and taught her how to operate it. When Babcock returned to the Chalet, Lacey lured him into the underground levels and used the Elizabeth Protocol to kill him, sacrificing herself.
