How I Installed GWX Knight's Cross Edition on Arch Linux

I love war games, especially those about World War 2 with historical weapons or machinery. I am fond of submarine simulator games with good mechanics and do not care much about graphics.

I managed to run the game with Steam using Proton. Later I discovered the megamod for Silent Hunter 3 called GWX - Knight’s Cross Edition, a successor to the Grey Wolves eXpansion.

I researched how to install it, joined their Discord server, and found someone explaining the process. I started by preparing all the necessary resources.

Installing Necessary Resources

Install the launcher from the AUR:

$ yay -S --noconfirm faugus-launcher

After installing the launcher, download the megamod files from MediaFire and install 7zip.

Remember to run the original Silent Hunter 3 from Steam once before doing anything else.

Putting It Together

Create a main entry in the launcher:

1. Open the launcher and create a new entry.
2. Fill in any title.
3. Enter the path: /home/user/Games/GWX-KnightsCross/sh3.exe.
4. Use the Steam prefix: /home/user/Faugus/gwx---knights-cross-edition.
5. Choose GE-Proton-Latest.

Create similar entries for HsieOptionsSelector.exe and MultiSH3.exe, using the same prefix and Proton version. Finally create an entry for SH3 Commander/SH3Cmdr.exe.

Conclusion

Run SH3 Commander when you want to play and manage career entries. Buy the original game on Steam first, and keep this megamod in a separate directory rather than merging it with the Steam installation.
