Q: What is the Aliens vs. Predator 2 master server patch (msp)?

The msp is an unoffical patch created by the AvP2 community (NOT MONOLITH) - That enables the user to once again play online multiplayer.

Q: What is the history of the master server patch (msp)?

The original multiplayer servers were shut down by Activision during the purchase of Sierra. The msp was first created by both Herr Alien & The One of LithFAQ (circa 2008). Once LithFAQ closed, the msp was then moved to be hosted at AVP UNKNOWN (Circa 2009) for download. and used by gamespy network till 2014, Development of the msp was then handed over to the player known as TBBC. TBBC hosted the actual server for some time until moving the msp application to the player known as Rommie. After a massive community backlash against Rommie for banning many players and servers, TBBC moved the actual msp application again to the players Smith, DT and Ayleia (AvP2MSP team). AvPUnknown is helping promote AvP2MSP. And TBBC then released the msp version 2.4 (With changelog) - from 2.3.4 - moved the master server to a more stable provider (Rommie can not update the MSP (the only thing he can do is add/remove maps) as TBBC Holds all the sources... if you are on MSP 2.3.4 (PLEASE UPDATE AS SOON AS POSSIBLE)



AVPUNKNOWN'S MSP SITE remains as a backup official site as it was originally cleared by Herr Alien and The One. (and still most known for avp2 online)

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: What is the error 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 before applying the patch. Uninstall the master server patch, apply the official patch, then re-install the master server patch.

Q: How do I get rid of the error client MFC application has stopped working?

Follow this guide here: CLIENT MFC ERROR GUIDE

Q: Why can I host a server but I not 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.

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 patch. What do I do to solve this?

Make sure you run the installer as an administrator.

Q: Is the msp 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 the msp compatible with the TBBC/SGB Server App?

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

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.

Q: I'm experiencing a bug/glitch with the msp. Where can I report this? I have a question not covered here. Where can I ask about it?
