Half-Life 2 is a 2004 first-person shooter (FPS) game developed and published by Valve Corporation. It was initially published for Microsoft Windows through Valve’s digital distribution service Steam. Like the original Half-Life (1998), Half-Life 2 combines shooting, puzzles, and storytelling, and adds features such as vehicles and physics-based gameplay. The player controls Gordon Freeman as he joins a resistance movement to liberate Earth from the control of the Combine, a multidimensional alien empire.
