"What's your name, dirtbag? Sound off like you got a pair! Corporal Shephard, huh? Looks more like Corporal "Dog Meat" to me! Seems your name was mysteriously bumped to the top of the advanced training list!"― Dwight D. Barnes (Drill Sergeant)

Corporal Adrian Shephard is a 22-year old US Marine Corporal assigned to the Hazardous Environment Combat Unit from the Santego Military Base, Arizona, where he was trained by Drill Instructors Dwight T. Barnes and Sharpe, and the protagonist of Half-Life: Opposing Force. He is one of the soldiers sent to the Black Mesa Research Facility to eliminate the Xen invaders. Shephard, however, is not aware of his mission to silence the witnesses, especially a scientist named Gordon Freeman, as part of a classified mission since his squad leader dies before revealing this.

Soon Shephard finds himself separated from his unit and ends up fighting solely for his life, aided by fellow Marines scattered around the facility and Black Mesa employees.
