Overview
Here’s a guide for simple tips on how to download and install mods for the original Half-Life
Downloading the mods
1. Find the mod and download it: You will first need to find the mod you want, so open up your web browser and search for it. Mods are typically downloaded off of moddb.com so I recommend you use that. (Warning: Make sure you’re careful where you’re getting your mods from because some can contain malware)
2. Click on the download button and wait for it to download. Once that’s done move the mod into your folder for Half-Life. A relatively simple way to do this is to right click on HL in your Steam library and select Properties, where you can then select Local Files then click the button that says “Browse”
Installing the mods
1. After the mods have been moved into your HL1 folder, check to see if the file needs to be compressed before you can unzip it
2. After that, right click on the mod and use an unzipping program like 7-Zip or WinRAR to unzip the file
3. After you’ve done that you should be all done
Starting up the mods
1. Once the mod has been properly installed, restart Steam by going to the upper left corner of your window, hovering over the button that says “Steam”, and clicking exit
2. Re-open Steam and after you’ve logged back in, the mod should now appear in your library (Note: The old library ui simply replaced HL1 with the mod you installed, the new one will not but don’t panic as it should now appear as uncategorized)
3. Click the play button and enjoy
