Installing official patches

Skip directly to the OpenMoHAA installation section if the MOH: Warchest copy is installed.

Otherwise, install the following patches:

Game	Patch to download and install
Allied Assault	Depends on the installed language: English, German, French Italian, Spanish, or Dutch
Spearhead	2.0 to 2.11, followed by 2.11 to 2.15
Breakthrough	2.40b

These patches are required to connect to multiplayer servers and ensure a smooth, bug-free single-player experience.

Downloading/installing

Ensure that you download the binaries compatible with your platform in the releases section.

Which release should be downloaded?

It depends on the OS that is installed on your device:

OS	Kind of hardware (CPU, platform...)	Archive
Windows	AMD/Intel	*-windows-x64.zip
Windows	Qualcomm/Snapdragon (ARM-based)	*-windows-arm64.zip
macOS	Apple Silicon (ARM)	*-macos-arm64.zip
macOS	Intel	*-macos-x86_64.zip
Linux	AMD/Intel	*-linux-amd64
Linux	Raspberry Pi 4 or 5	*-linux-arm64

Once the correct archive was downloaded:

a) Extract the archive¹ to your MOHAA installation directory.

-or-

b) Extract the archive¹ somewhere on your hard drive, create a shortcut to each of the launch_openmohaa_* executables (or omohaaded.exe), and set the shortcut's 'Start in' directory to your MOHAA installation directory.

Once you're ready, start one of the three launchers based on whether you want to play the base game, Spearhead, or Breakthrough, and then you can start playing.

---

Notes:

1. For servers, only the omohaaded.* and game.* binaries from the archive are required.

Cleaning up the game installation directory

If you want to clean up the mohaa installation directory by keeping only what is needed for OpenMoHAA, the following files/directories can be kept:

[MOHAA]
├── [main]
|   ├── [sound]
|   ├── [video]
│   ├── Pak*.pk3 // all pak files
├── [mainta]
|   ├── [sound]
|   ├── [video]
│   ├── pak*.pk3 // all pak files
├── [maintt]
|   ├── [sound]
|   ├── [video]
│   ├── pak*.pk3 // all pak files
├── All files from the OpenMoHAA archive

Extracting GOG setup file on Linux and macOS

If your MOH:AA copy was acquired from GOG then this section will be relevant.

The MOH:AA Warchest installer files on GOG are Windows binaries. To attain the game files, you can quickly extract them using Innoextract.

• Install Innoextract using your preferred Package Manager (e.g. Brew).

• Once installed run the command innoextract setup_medal_of_honor_2.0.0.21.exe. The MoH:AA game files will be extracted into a folder called 'app'.

Alternatively, you can use WINE as well, but this process may take longer if you do not already have WINE installed and configured.

Alternatively, free demo versions are available online. Here are the links to the demos:
