At the age of 19, she performed reconnaissance missions, and was friends with Russell and Olga. Although the initial model was a mere meter high, Alyx added new parts to Dog over time, making him a towering 2.5 meters high at the time of Half-Life 2.Īs Alyx reached adulthood, she began working with the Resistance, as one of the core members of the City 17 branch.
During Alyx's childhood, Eli used scrap metal to create Dog, a sentient robot designed to protect her, making him physically powerful, intelligent and with an in-built sixth sense so that he could always know Alyx's whereabouts. During this time, Alyx was also on good terms with Isaac Kleiner, referring to him as "Uncle Kleiner" in an affectionate portrait she once offered him. Alyx was apparently too young to remember this (she does not recognize the G-Man when meeting him as an adult), and although Eli witnessed it, he never shared the story with her.Īlyx was raised by Eli in the world controlled by the Combine, likely at Black Mesa East much of the time. During the course of the incident, the G-Man was instrumental in rescuing Alyx, despite the objections of unnamed naysayers. When the Black Mesa Incident occurred, Eli managed to escape along with Alyx and a family picture, while Azian was killed in the incident. As a young child, Alyx lived in the dormitories within the confines of the Black Mesa Research Facility along with her father Eli and her mother Azian, while Eli was working at the Sector C Test Labs.
