Half-Life: Opposing Force is an expansion pack for Valve Software's science fiction first-person shooter video game Half-Life. The game was developed by Gearbox Software and published by Sierra Entertainment on November 1, 1999. Opposing Force is the first expansion for Half-Life and was first announced in April 1999. Randy Pitchford, the lead designer on the game, later noted that he believed Gearbox was selected to develop Opposing Force because Valve wanted to concentrate on their future projects. Over the course of development, Gearbox brought in a variety of outside talent from other areas of the video games industry to help bolster various aspects of design. Opposing Force returns to the same setting as Half-Life, but instead portrays the events from the perspective of a U.S. Marine, one of the enemy characters in the original game. The player character, Adrian Shephard.

The protagonist isnt as great a Gordon Freeman, but Corporal Adrian Shephard is not bad at all.

But if he and Gordon had cross paths, things would have ended up badly.

A great expansion to an awesome game.

No Half-Life or FPS player would hate this mod! Awesome gameplay, a satisfying arsenal of weapons, the enemies... AND SO MUCH MORE!!! HL:OF rocks! \m/

Just, the gameplay, NPCs, storyline... this game is just better than the original one!

One of the BEST expansion packs ever made.

Because it's another game where players rage at the devs for not making a sequel.

I didn't expect it to be so good. The plot is f*cking awful, but the gameplay is real fun.

NIIIIICE
