Houser was an engineer living in Vault 34.
Houser is mentioned only in Fallout: New Vegas.
- The Courier: "The radiation down there would kill you, Chris. Because you're human."
Chris Haversam: "I thought we were past all that, smoothskin. But you just can't resist the chance to mess with me. Typical human. I was human once, you know. Grew up in Vault 34, northeast of here. Nice upbringing, if you like assault rifles and target practice. But oh, you prefer machines that don't shoot people? Not so nice then. Who should maintain the Vault's reactor? Houser? Mitchell? No - make it Haversam. He likes machines! Haversam won't mind getting irradiated! Haversam won't mind mutating! He's already ugly as it is! Haversam won't mind when his hair starts falling out after a few years. There's no connection, Haversam! You're neurotic!"
