Previous game

Half-Life 2: Episode One is the first in a series of games that reveal the aftermath of Half-Life 2 and launch a journey beyond City 17. It focuses on developing Alyx as a character.

Consciousness returns. Gordon and Alyx discover they've somehow escaped both the reactor explosion and the G-Man's malevolent grasp. Before they can ponder their miraculous survival, the crippled Citadel lurches back to life just long enough to initiate a self-destruct sequence. With Alyx at his side, Gordon must flee a city in chaos before the Citadel's final detonation turns City 17 into a toxic, mutant-infested crater.

Aside from the story, the game initially runs on Source 2006, which introduced new features such as HDR, Phong shading, and much more. The game was later upgraded to Source 2009, then again with Source 2013 Singleplayer.
