This will allow them to summon reinforcements and destroy the Resistance. In the mountains outside City 17, Resistance fighters Gordon Freeman and Alyx Vance climb from the wreckage of the train they used to escape the city. At an old transmission station, they establish communication with resistance scientists Dr. Kleiner and Eli Vance at the White Forest base. They learn that the Resistance may be able to close the portal using a copy of a Combine transmission Alyx is carrying. At an abandoned mine, Alyx is critically wounded by a Combine Hunter. A vortigaunt leads them to an underground Resistance shelter. Gordon recovers larval extract from a nearby antlion colony, necessary for the vortigaunts to heal Alyx. While the vortigaunts heal her, the mysterious G-Man contacts Gordon and hints at Alyx\'s importance to his own plans, revealing that he saved her life at the Black Mesa Research Facility despite objections from an unspecified third party. He instructs the unconscious Alyx to tell her father to "prepare for unforeseen consequences".']}}]}]
