Hello, I am professor plusx2. Today we will be installing a Black Mesa moddb mod. First, go into your browser of choice, then type www.moddb.com/games/black-mesa. Then, click on the mods section.

Click on a mod you like, but for example, I will do Black Mesa: Military A: for I already have Azure Sheep, and B: I wanna play it. Anyways, then, go to "Files" at the top, and click on the files for the mod, or in my case Part 1. Then click "Download Now," and wait for it to download.

Open the .rar file and extract it to X:..Program Files (x86)/Steam/steamapps/common/Black Mesa, or in my and or your case X:Program Files/SteamLibrary/steamapps/common/Black Mesa. Then, let it extract. Then open BMS or launch the mod from its file path.

Thank You for reading this guide, and if I missed something, tell me in the comments. This has been cooking with professor plusx2.
