Before you begin, it is important that you have the following ports open on your router so that others can connect to your server without problems:

• UDP and TCP - 27015
  
• UDP - 27005

The first thing we’ll do is download the Black Mesa Dedicated Server tool directly from Steam.



Once installed, we’ll locate the folder where it is stored. To do this, open the Steam library, right-click on the tool, select "Manage" and then "Browse local files".



Now we’re going to configure the srcds.exe file so it always runs as administrator. This is key to avoid issues when starting the server.



Next, we will configure the main server file. Go to the path:

"Black Mesa Dedicated Server\bms\cfg"

Inside the "cfg" folder, look for the file named server.cfg and open it with a text editor.



Here we’ll configure the basic parameters of our server. Pay attention to the following values which you can adjust as you see fit:


Once you've adjusted these values, remember to save the changes before closing the file.

Now open the CMD command terminal in Windows. From there, navigate to the folder where the tool is installed. Use the following command:

cd "C:\Program Files (x86)\Steam\steamapps\common\Black Mesa Dedicated Server"

⚠️ Remember that the path may vary depending on where you installed Steam.

Now run the following command to start our server:

srcds.exe -console -game bms +ip 192.168.1.107 +map dm_crossfire +maxplayers 32 -port 27015



And here’s what each part of the command does:


❓ Don’t know your local IP?

If you don’t know your local IP, just do the following:

Press Windows + R, type cmd, and hit Enter.

In the black window, type: ipconfig

Look for "IPv4 Address".
For example: 192.168.1.107 — that’s your local IP.



If everything is correct, a new window will open showing the server console running.

In this case, to create a dedicated server for Co-op, you’ll need to download the following file:

▶ https://drive.google.com/file/d/1xpH9AwMbcAcT3uHPDHW_VSspAyXxIXHv/view?usp=sharing

Once downloaded, go to the folder where your game is installed and navigate to the following location:

> Black Mesa Dedicated Server\bms



Inside that folder, extract the compressed file you downloaded.

Next, you’ll need to configure the main server file. Go to:

"Black Mesa Dedicated Server\bms\cfg"

Inside the "cfg" folder, look for a file called server.cfg and open it with a text editor.



Here you’ll configure the basic parameters for your server. Pay attention to the following values, which you can modify to your preference:


Once you’ve adjusted these values, remember to save the file before closing it.

Now open the Windows command prompt (CMD). From there, navigate to the folder where the tool is installed using the following command:

cd "C:\Program Files (x86)\Steam\steamapps\common\Black Mesa Dedicated Server"

⚠️ Remember, the path may vary depending on where you installed Steam.

Now run the following command to start your server:

srcds.exe -console -game bms +ip 192.168.1.107 +maxplayers 10 +mp_teamplay 1 +exec server.cfg +map bm_c4a1a



Here’s what each part of the command does:


❓ Don’t know your local IP?

If you don’t know your local IP, just:

Press Windows + R, type cmd, and press Enter.

In the black window, type: ipconfig

Look for where it says "IPv4 Address."
Example: 192.168.1.107 — that’s your local IP.



If everything is correct, a new window will open showing your server console running.
