City 17 is on the verge of collapse. It’s a race against the clock to save humanity.
Picking up after the events of Half-Life 2, scientist Gordon Freeman and Alyx Vance attempt to slow an unavoidable chain reaction that will destroy City 17. Facing heavy resistance, they must evacuate the city and save its residents before all is lost.
Picks up right after 2004's Half-Life 2, and while it covers terrain from the last game—zombie-strewn tunnels, squad-based street battles—it's more compelling in every way.
Episode One provides another chance to hurl items with the fabulous gravity gun, blast the relentless Combine forces and learn more about the fascinating Half-Life universe as Gordon escapes from the devastated City 17.
