# Running

## 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 Spearhead (mohaas/mohta, mainta)
- `+set com_target_game 2` for Breakthrough (mohaab/mohtt, maintt)

On Windows, you can create a shortcut to OpenMoHAA with these command-line arguments.
The default value of `com_target_game` is 0 for the base game (mohaa, main).

With `com_target_game`, OpenMoHAA will support the network protocol accordingly.

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.

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.
