Half Life 2 Walkthrough 04 - Route Kanal 03

After the alien invasion at the Black Mesa Research Facility, a multidimensional alien empire known as the Combine has conquered Earth. Approximately twenty years after being placed in stasis, Gordon Freeman is inserted into a train bound for City 17 by the G-Man (Michael Shapiro). Helped by the undercover Resistance member Barney Calhoun (Shapiro), Gordon attempts to reach the laboratory of Dr. Isaac Kleiner (Harry S. Robins) but is subdued by Combine officers. He is rescued by Alyx Vance (Merle Dandridge), who guides him to the laboratory. Kleiner's attempt to teleport Gordon to the Resistance base fails, and Gordon is momentarily teleported to the Citadel, the skyscraper headquarters of Dr. Wallace Breen (Robert Culp), the former Black Mesa administrator and the Combine's puppet ruler. Gordon progresses to the base using the city's canal system using an airboat, eluding Combine forces.
