Project "Savior" is a mod designated to increase the lifespan of AvP2 internet multiplayer games, by providing an alternate master server. The aim is also to keep the user experience the same. It will basically allow players to find and join online AvP2 multiplayer servers. What happens next is up to the players' skills.

8 comments by Herr_Alien on Feb 11th, 2010

What happens when a strong headed community is faced with a problem such as getting the list of servers for their favourite game?
You get the master server patch:

Reaching version 1.5.1, the following features must be noted:

  • server list retrieved from Gamespy: this means AvP2 will be playable online for as long as Gamespy exists.
  • game servers running version 1.3 or higher do not have to update!
  • fixed the punkbuster-like player ID algorithm. This means (for server administrators) that is somebody ticks you off, you can ban him from that server.

So, get it while it's hot, and I hope I'll see you online!

The master server patch, final version. Object.lto is now residing in its own .rez file, lithserv.rez. This improves or even completely removes crashes...

Well, no, it seems that I'm doing something wrong with the auto-update functionality.

What you should do is to download the 1.5.1 patch. Since you already have 1.5, you're better off with the 1.3 to 1.5.1 patch. See the Downloads section.

It could be that they are banned in the default server configuration. Head to for more info, it's pretty well documented there.

Hmm, I seem to be having that same problem with the I/O 123 error message on the 1.5, is it possibly because I use Vista x64?

Also, I keep UAC turned off

@thewonderboy: try running the installer as an administrator.
Aditionally, if you have issues with gslist (the command line gamespy client), you may want to go through this tutorial:
