Half-Life: Opposing Force is the official game expansion for Half-Life, the thrilling
PC CD-ROM named "Game of the Year" by over 50 publications. In Opposing
Force (a.k.a. "Op For"), players return to the Black Mesa Research Facility
to experience an entirely new episode of single player action. In addition, Op For
also contains a massive collection of new multiplayer content.
Remember the soldiers who gave you so much trouble in Half-Life? Now you are one
of them--and life is not so easy as part of the 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
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.
But as a military specialist, you are not unarmed. You'll gather a custom arsenal
of new military firearms, experimental weapons and deadly alien devices. And, as
you explore further areas of Black Mesa, you will encounter a new variety of human
characters to interact with--on both friendly and unfriendly terms.
In addition to the extensive new single player experience, Opposing Force will also
contain a robust collection of fresh multiplayer content, including new weapons,
player characters (models), and several new multiplayer maps designed by the experts
at Gearbox Software. Opposing Force will also feature new levels created by all-star
legends of the Dallas gaming community.
