Q: What is the Aliens vs. Predator 2 Master Server Patch (MSP)?

The MSP is an offical patch created by the AvP2 community that enables the user to once again play online multiplayer. AvP2's online multiplayer will not work without this patch as the original multiplayer servers were shut down by Activision during the purchase of Sierra. The MSP was first created by Herr Alien & The_One with the help of The One of LithFAQ. The MSP was then passed on to AvPUnknown, Where The One & Putmacher now contributes to its further development.

Q: Is this the new official site for the Master Server Patch?

Yes! The original developers (Herr_Alien) & (The One) from LithFaq has given us permission to make AvP Unknown the new home and official site for the MSP.

Q: Whenever I try to find a game it just closes the program! I am on Vista!!

Windows Vista has introduced a new feature that stops unwanted programs from starting and executing code on the users machine. However, this breaks a lot of compatibility with other programs. Turn off UAC and try it again. You can find the option in your user account which is accessible via the control panel.

Q: It is possible to use this new master server with Primal Hunt?

Unfortunatley, no. The reason for this is because Sierra/Fox/Monolith never released the source code. The "source code" is required to make changes in the game. Without it, nothing can be changed. However, we do have a 'HIGHLY EXPERIMENTAL' version of it, which is known to work.

Q: World version is different from the server.

This is caused either because the server is using a map pack (UMP2/3 for example), mods or because your AvP2 game installation was not updated to version 1.0.9.6 before applying the patch. Uninstall the master server patch, apply the official 1.0.9.6 patch, then re-install the master server patch.

Q: Client MFC Application has stopped working.

Several firewall packages can interfere with the master server patch. Stop these programs if they are running on your machine:
AVG Webshield
Norton Internet Security
Norton Personal Firewall

Q: I can host a server but I can't join my own server?

This is caused by having different rez files specified on the command lines for the game server and the game client. The game client command line is the one visible when double clicking AvP2.exe -> Options. The game server has it's rez files specified in "customrez.txt".

Q: Any news on Linux support on this patch? Or is that asking way to much?

Unfortunately we didn't succeed in building the needed binaries for Linux. Sorry.(Maybe one day?)

Q: How about Mac support on this patch?

For Mac the situation is even worse, since besides the missing tools (compiler) we don't have Macs.

Q: I get the error "could not write avp2p5.rez"? when installing the mod. Help?

Make sure you run the installer as an administrator.

Q: Is this compatible with the Bunny server mod?

Yes, it is. Install the Bunny mod, then install the master server mod (and yes, install the dedicated server from the patch). Add the avp2p5.rez to the customrez.txt and you're good to go.

Q: Is this compatible with the SGB-Mod?

Yes, it is!  Our very own server (WWW.AVPUNKNOWN.COM - TDM) uses it. Great security!

Q: Sometimes My Aliens vs. Predator 2 Crashes (is this patch related?)

Unknown. This could be due to the fact your game is missing certain files to complete the installation.

Q: I experience lag with the MSP?

There are some reports of users experiencing lag on the in-game menus and tab overlays. Hopefully this can be fixed in a future update.
