Half-Life: Alyx is virtual reality's return to the Half-Life series. It tells the story of an unlikely battle against an alien race known as the Combine, set between the events of Half-Life and Half-Life 2. You play as Alyx Vance, who alone represents humanity's hope of survival.

A menacing Combine

Since the Black Mesa incident, the Combine has dominated the planet and tightened its grip on the remaining urban populations. Among them were some of Earth's greatest scientists, including you and your father, Dr. Eli Vance. As founders of the nascent resistance, you continued your secret scientific work - conducting critical research and building invaluable tools for the courageous people who oppose Combine.

A Chance for Humanity

Every day, you learn more about your enemy and try to find a weakness. As the battle intensifies, you and your combine-resistant team embody humanity's only chance of survival. With the tools you've created, you may be able to save the planet from total control.
