Gordon arrives at a small Resistance outpost within the mines manned by Griggs and Sheckley. The Vortigaunt has brought Alyx to the outpost and is awaiting the arrival of his kin in order to heal her wounds. Griggs and Sheckley introduce Gordon to the Antlion Detector, and with the aid of reprogrammed Hopper Mines and Sentry Guns they are barely able to hold off several Antlion attacks until the Vortigaunts arrive. The Vortigaunts assist in dispatching the next wave of Antlions, and proceed to tend to Alyx. The Vortigaunts require the Antlion larval extract to save Alyx, so Gordon and his Vortigaunt companion travel deeper into the mine to retrieve it.
