This chapter sees Gordon and Alyx fleeing through the city’s ruined, dark, and zombie-infested City 17 Underground as they continue to flee the city.
Alyx is trapped under a Combine Prisoner Pod with a restrained Stalker viciously attempting to break loose, relying on Gordon to set her free.
After escaping from the train, the duo fights through the rubble of dark, deserted, underground parking garages and tunnels, searching for a way to head up to the surface of the city.
In the process, they block off Antlion burrows, and battle various zombies in a pitch black environment, including zombified Combine soldiers, which were never seen during Half-Life 2.
These zombified soldiers, referred to as “Zombines” by Alyx, are a prominent sign that the Combine is losing control of City 17.
After Alyx opens the first EMP Field Gate, if the player zooms in on her face while standing next to her, she will nervously look away playing with her hair and then look up at the player, smiling.
She will do the same thing after leaving the underground in the next chapter, and again in Episode Two after opening the Radio Tower Base gate in Riding Shotgun.

I won’t be covering the Episode One achievements in the same way as I did in the Half-Life 2 TREE event, because they are less chapter based. However, HLFallout.Net has an excellent guide that I can highly recommend.
