Then a mod called "Project Savior" was released, which offers an alternative master server. Using this mod, players can once again browse for servers on the internet.
Here I'll explain where to get it and how to install it properly to avoid a bug with the auto updater.
Please be kind and use the Adfly links as a gratitude.
Step 1
Update AVP 2 to the latest version, which is "1.0.9.6" .
You can download the update from here:

Step 2
Download the Project Savior mod from here (Master Server patch):

Step 3
Install Project Savior. If you are using Windows 7 or Vista, remember to run it as administrator.
You will have to uncheck the "Easy update" option when installing the mod. Otherwise the game won't let you play unless you update the game, and the updater won't work and will give you this error:
"I/O Error 123."
We already updated the game in step 1, so don't worry about updating.
Step 4
Enter the game, and select "MULTIPLAYER INTERNET". The game will ask you to update the game, press OK. There will be no update and you will be able to host or find internet games!
That's it!
Now you can play Aliens Vs. Predator 2 multiplayer over the internet!
