Half-Life: Opposing Force Cheats

Half-Life: Opposing Force is an expansion pack for Valve's science fiction first-person shooter video game Half-Life. The game was developed by Gearbox Software and Valve and published by Sierra On-Line on November 19, 1999. Opposing Force is the first expansion for Half-Life and was announced in April 1999. Randy Pitchford, the lead designer on the game, later noted that he believed Gearbox was selected to develop Opposing Force because Valve wanted to concentrate on their future projects. Over the course of development, Gearbox brought in a variety of outside talent from other areas of the video games industry to help bolster various aspects of design.
