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.

Description

Sandpit v4.1 adds a new Sprite Menu, some Opposing Force entities, entity scaling and more.

I can't - a few core features rely on Steam-only functionality.

Markus_Scrovisk what are you doing to get this to happen? Which games are you mounting? If you change your mounting settings mid-game this might happen too (gameui.dll doesn't propagate changes properly or something?).

Will you add some turrets like at the office part(Half-Life 1), and its impossible you to make the tanks and could you add some modded npcs(if you could).

JohnCresa yeah I might be able to - would just need to rotate them so they're not upside down.
Tanks are brush-based so I can't add them. I'm looking to add more Opposing Force monsters at this point.

i figured out what that comment meant. if you want to mount a game's content, you'll need to have that game downloaded on steam, otherwise you won't be able to load any maps at all, even if you choose to unmount the game, forcing you to restart sandpit

When I install sandpit and create a server or start a game, I try to activate the npcs menu, props menu or sprites menu it does not activate, and in the game console it says "Unknown command + monstermenu / + propmenu / + spritemenu ", I activate sv_cheats 1 but still nothing :( I hope you can help me, greetings from Chile!

PSone that happens when you don't own Half-Life.
If you do, can you run the game with the -condebug parameter and paste the contents of console.log?
