Allen Mack

 is a resident of Vault 101 in 2277.

Background
Wally Mack's father is not a man to be trifled with. He is overly protective of his family ever since the death of his wife (mother of Wally Mack, Susie Mack, and Officer Mack). He's taught basic survival skills to his children but isn't overly fond of showing emotion. Should Overseer Almodovar ever become incapacitated, Allen has vowed to take over the running of Vault 101.

Relationships
Allen Mack is the husband of Gloria Mack, and the father of Wally, Steve and Susie Mack. His father-in law is Stanley Armstrong, and he's got two sisters-in-law, Beatrice Armstrong and Mary Kendall.

Other interactions
During the quest Escape!, he can be seen in his room shouting to the player. He can be shot through the glass and killed.
