Half Life: Opposing Force has you play as a tactical team sent to investigate Black Mesa during the time of Gordon Freeman and Barney Calhoun. There are new weapons and you have a team to fight along with. The only problem is that there is not enough new content, way too short, and too enemies to shoot.
