Half-Life 2: Episode One – Steam Key – Global

Half-Life 2: Episode One is a thrilling continuation of the iconic Half-Life series, where players reprise their role as Gordon Freeman, the scientist turned hero. Picking up right where the original game left off, Episode One takes players on a heart-pounding journey through the devastated City 17 as they fight against the oppressive Combine forces. After the six-year development of Half-Life 2, Valve switched to episodic development, hoping to release games more frequently. For Episode One, they focused on developing the character of Alyx and expanded her artificial intelligence. It uses an updated version of Valve’s Source engine, with new lighting and animation technology. Half-Life 2 has sold over 4 million copies worldwide, and earned over 35 Game of the Year Awards. 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.
