Aiden Higgins was a Vault 51 dweller who perished under ZAX's rule. A lawyer and, according to himself, the "winningest" one in the state, Higgins was reassigned to a communal living room by ZAX and reacted... Poorly to the change. In February 2078, he decided to attempt to break out of the Vault, inadvertently blowing up himself and the Vault's lounge up.
Aiden Higgins is mentioned only in Fallout 76.
