Half-Life 2

Half-Life 2 is a first-person shooter set on an alien-infested Earth after the Seven Hour War, in which humanity has surrendered. Earth’s resources are depleted and its population is dwindling. You play as research scientist Gordon Freeman, taking up his crowbar again and trying to rescue the world from the disaster he unleashed at Black Mesa, while people he cares about depend on him. The campaign combines combat, physics and a detailed game world.

Episodes One and Two

The story continues in two full-length Half-Life adventures set after the events of Half-Life 2. Both are accessible from the main menu, and completing one automatically advances you to the next episode.

Deathmatch

Half-Life 2: Deathmatch offers fast multiplayer matches in the Half-Life 2 universe, with physics adding another dimension to play. You can play standard deathmatch or team up in Combine vs. Resistance.
