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.

I've gotten tired of not being able to reliably find games for old Gold Source (GoldSrc, HL1, Half Life 1) mods or Source (Half Life 2, HL2) mods, so I made a discord about just that. I am also trying to make this place an informational hub. I'm trying to centralize and unite the multiplayer mod communities for all of the various multiplayer mods out there. We play a mod of the week every Friday/Saturday.

Check us out.

I also saw and already played a game that you enter into the skin of a black table visitor, the name of the game is half life visitors, he is in this group to download, works only via steam, it will be possible someday convert it to ps2.
