Game selection

Medal of Honor: Allied Assault is the default game, but expansions are also supported.

Medal of Honor: Allied Assault Spearhead and Medal of Honor: Allied Assault Breakthrough are supported in OpenMoHAA using the com_target_game variable.

To play an expansion, append the following command-line arguments to the executable:

  • +set com_target_game 1 for the Spearhead expansion (mohaas/mohta, mainta, a.k.a Team Assault)
  • +set com_target_game 2 for the Breakthrough expansion (mohaab/mohtt, maintt, a.k.a Team Tactics)

With com_target_game, OpenMoHAA will support the network protocol accordingly. The default value of com_target_game is 0 for the base game (mohaa, main).

On Windows, it's best to create a shortcut to the OpenMoHAA executable, and append the command-line arguments above to play an expansion.

You can now start a local OpenMOHAA server or play on a server.

User data location

The location of user-writable data, like the console logfile, saves and configuration files can be found in different locations depending on the platform:

  • %APPDATA%\openmohaa\<game_name> on Windows
  • ~/.openmohaa/<game_name> on Linux

This is by design since ioquake3 and has two advantages:

  • On a multi-user system, each user will have their own configuration file
  • It doesn't overwrite the existing MOHAA configuration in the MOHAA installation directory.

If necessary, the location of user-writable data can be changed manually by setting the fs_homepath variable in the command-line argument. This is useful when running a dedicated server that can only use the game directory to store/read data. The value can be a relative path (relative to the current working directory) or an absolute path. Example:

  • +set fs_homepath Z:\openmohaa_data data will be written inside the fully qualified path Z:\openmohaa_data
  • +set fs_homepath homedata will use the subfolder homedata in the process current working directory to write data (will be created automatically)
  • +set fs_homepath . not recommended, will write data inside the process current working directory

The game directory is intended to be read-only, which is the reason why the home path exists. This prevents existing files in the game directory from being accidentally overwritten.

Note that the configuration file isn't created nor written automatically on a dedicated server (omohaaded).

Playing with bots

OpenMoHAA has a basic bot system that emulates real players. The maximum number of bots is defined by the sv_maxbots variable, and the number of initial bots is defined by the sv_numbots variable. Bots can also be added or removed using the addbot and removebot commands.

This feature is a great way to test the gameplay and mods.

Note that maps must have path built for bots to move, multiplayer maps don't have path built by default. Mods like eagleAR bots exist that do introduce paths in multiplayer maps.
