Half-Life: Opposing Force is an expansion pack for the first-person shooter game Half-Life. It was developed by Gearbox Software and published by Sierra On-Line for Windows on November 19, 1999. Opposing Force was the first expansion for Half-Life and was announced in April 1999. Lead designer Randy Pitchford noted that he believed Gearbox was selected to develop Opposing Force because Valve, the creators of Half-Life, wanted to concentrate on their future projects. Over the course of development, Gearbox brought in a variety of talent from other areas of the video games industry to help bolster various aspects of design.
Opposing Force portrays the events of Half-Life from the perspective of a U.S. Marine, one of the enemy characters in the original. The player character, Adrian Shephard, is sent in to neutralize the Black Mesa Research Facility when a scientific mishap causes it to be invaded by aliens, but quickly finds that the Marines are outnumbered and slowly being beaten back by a second alien race and black operations units.
Opposing Force was received well by critics, with many describing it as the new benchmark title for expansion packs, in a similar fashion to how Half-Life revolutionized the first-person shooter genre. Other reviewers, however, thought that it still had many of the negative aspects of other expansion packs, although it was still regarded as an exceptional add-on.
