Half-Life: Opposing Force
The Game That Started It All
About Half-Life: Opposing Force
As a soldier sent in to eliminate Gordon Freeman, you are separated from your base unit and discover a new alien race amidst the chaos. It’s quickly revealed that these highly advanced alien life forms descended upon Earth to pillage the planet from the Black Mesa facility when Gordon Freeman transported to the border world of Xen.
Although you were originally sent into Black Mesa to silence Freeman and his fellow scientists in the facility, you now find yourself stranded and confused–battling fierce new alien creatures and a variety of other foes in an effort to save your own life.
