Medal of Honor: Allied Assault

Instructions for connecting Medal of Honor: Allied Assault, Spearhead and/or Breakthrough to the 333networks masterserver.

Medal of Honor: Allied Assault does not have configuration files that can be modified to use the 333networks masterserver. Instead, it is necessary to patch the executable files to start the game and/or server.

Be careful with installing third party software. 333networks is not liable or responsible for this external content. Read the patch notes and verify third party content before installing.

The relevant executables can be found in the following location(s):

C:\GOG Games\Medal of Honor - Allied Assault War Chest\

Don't want to patch your binaries?

We know that there are circumstances where it's either not possible or not desired to update your binaries. As an alternative solution, it possible to change the HOSTs file with a different masterserver ip-address. By editing the HOSTS file, you override the DNS settings of the currently configured masterserver and replace it with a 333networks masterserver address.

81.205.81.173    master.gamespy.com

The code block above contains the current IP address of master.333networks.com, copy it to your HOSTS file and save the file. You may have to restart your computer for this change to take effect.

Read the full instruction manual on how to modify your HOSTs file here.

Alternatively....

A project called OpenMoHAA, an open-source reimplementation of Medal of Honor: Allied Assault, uplinks to 333networks directly. You can download and install it by following OpenMoHAA's instructions on their website.
