b) Extract the archive<sup>1</sup> 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.
The MOH:AA Warchest installer files on GOG are Windows binaries. To attain the game files, you can quickly extract them using [Innoextract](https://github.com/dscharrer/innoextract).
- Install Innoextract using your preferred Package Manager (e.g. [Brew](https://brew.sh/)).
- 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](https://www.winehq.org/) as well, but this process may take longer if you do not already have WINE installed and configured.
- MOH:AA singleplayer demo ships with the level: **Mission 3: Level 3**.
- MOH:AA multiplayer demo ships with the level: **Stalingrad**. **The Hunt** can be added with the [MP Demo addon](https://www.gamefront.com/games/medal-of-honor/file/mp-demo-add-on-the-hunt).
