He is Susie and Wally Mack's brother, and Allen Mack and Gloria Mack's son. Stevie is 25 years old as of the events of Escape! He is a sadistic and gung-ho member of the Vault's security force, and willing to do anything to gain favor with his boss, including being particularly overzealous during emergencies.[Non-game 1]
Escape!: Officer Mack is found in the security office interrogating Amata. If the Lone Wanderer took the overseer's gun from Amata, they have no choice but to fight Mack, due to the fact that he attacks them on sight. If one insisted Amata keeps her father's gun to protect herself, she will shoot Mack in self-defense, killing him. If you interrupt before Amata fires on him, she will escape and the player character will again be responsible for killing Mack.
Trouble on the Homefront: If not killed in Escape!, Mack is found in the vault upon returning. He is not hostile.
A teenaged Stevie was originally slated to appear during the birthday party in Growing Up Fast. An unused model exists in the G.E.C.K., and a single line of dialogue for the quest can be found in the files as well.
↑The Lone Wanderer: "Thanks, Officer Gomez. I always liked you." Officer Gomez: "It's a real shame it's come to this. I can't believe what they did to Jonas... Officer Mack was just out of control... But you're a good kid. You didn't do anything to deserve this. Go find your dad, if you can." (Herman Gomez's dialogue)

↑Fallout 3 Official Game Guide Game of the Year Edition p.96: "Officer Steve "Stevie" Mack Stevie is the gung-ho new guy in security. He's been waiting his whole life to join the force and is willing to do whatever it takes to get in good with "the boss" (Chief Hammond), including being particularly overzealous during emergencies."
