Vault 43

Vault 43 was one of the Vaults created by Vault-Tec, and part of the Vault Experiment. Only 20 men, 10 women and one panther entered this Vault. It can be assumed that either the panther killed all of the residents, the residents closed part of the Vault away from the panther, or some smart guy with a gun shot the panther dead. Any other Vault defects are unknown. It is possible that the panther attacked several of the residents, who then trapped themselves in an area without food or water. Its location is unknown.

Appearances
Vault 43 appears only in the official Fallout 3 Penny Arcade Comic, written by Jerry Holkins and illustrated by Mike Krahulik, in cooperation with Emil Pagliarulo.
