I can't get the original campaign to work

[Alexis Wasilla]

For some reason a long time back I did some ♥♥♥♥ to play a mod port of decay, but now for wahtever reason it overrides Opposing Force's campaign, it always shows "play decay" and "find servers" there's no way to actually play the actual ♥♥♥♥♥♥♥ campaign is there any way I can just reverse engineer the original content of the game back to fix this I literally ahven't found a single way to fix it, I tried to remove the game completely to buy it again but then it turns out I couldn't do THAT. Please for the love of god let there be someone who knows how this could be fixed I literally can't find anything liek this

You need to uninstall everything released to Half Life 1 including any other gold source games like blue shift or counter strike, and also make sure everything in the games folders are deleted before you reinstall the game.

Got to c/programfilex86/steam/steamapps/common/ and Delete the entire Half Life folder

This goes for any game you uninstall through Steam because Steam doesn't always delete everything in the games folder
