Half-Life is a science fiction first-person shooter video game developed by Valve Software and the company's debut product. First released by Sierra Studios on November 19, 1998, the game was also released for the PlayStation 2 on November 14, 2001.[2] Valve, set up by former Microsoft employees, had difficulty finding a publisher, with many believing that the game was "too ambitious". Sierra On-Line eventually signed the game after expressing interest in making a 3D action game. The game had its first major public appearance at the 1997 Electronic Entertainment Expo. Designed for Microsoft Windows, the game uses a heavily modified version of the Quake engine, called GoldSrc.[1][3]

In Half-Life, players assume the role of Dr. Gordon Freeman, a recent graduate theoretical physicist who must fight his way out of a secret underground research facility, whose research and experiments into teleportation technology have gone wrong.
