Patient Zero

Patient Zero is a unique spore carrier found in the Big MT.

Background
The origin of the creature comes from a human patient that died when the virus, later used in Vault 22, infected him/her. He/she was considered a failed experiment by the Big MT Scientists, and the body was left alone. However, when the scientists returned to the laboratory the body of Patient Zero had disappeared and now can be found at the X-22 botanical garden.

Appearances
Patient Zero appears only in the Fallout: New Vegas add-on Old World Blues.
