S2x (Call of Duty: WWII)

Before you start

S2x is a community client for Call of Duty: WWII, and it is still an early test build. Expect crashes, rough edges and features that change from one update to the next. Builds can be swapped out or pulled at short notice, so if something that worked yesterday stops working today, check the S2x Discord before assuming you broke it.

What you need

• Call of Duty: WWII installed through Steam, or through the Microsoft Store / Xbox app.
• A Windows PC.
• The S2x launcher, s2x.exe. Only take it from the S2x project itself: updater.s2x.dev/s2x/s2x.exe. A copy rehosted somewhere else is not something you can trust.

Install steps

1. Install Call of Duty: WWII and let it finish downloading.
2. Download s2x.exe from the link above.
3. Find the game folder:

• Steam: usually C:Program Files (x86)SteamsteamappscommonCall of Duty WWII. If you installed to another drive, right-click the game in your Steam library and pick Manage → Browse local files.
• Microsoft Store / Xbox app: this is wherever you told the Xbox app to put the game. Open that folder so you can see the game's own files.

1. Move s2x.exe into that folder, next to the game's files. It has to sit in the game folder itself, not in Downloads or on the desktop.
2. Start the game by running s2x.exe. Launch it the same way every time; if you want a shortcut, make one that points at s2x.exe.

Checking it worked

• The game should open through S2x rather than the stock Call of Duty: WWII menus.
• If it starts as the normal game, you launched it from Steam or the Xbox app instead of s2x.exe.

Troubleshooting

• The launcher can't find the game: s2x.exe is in the wrong place. Move it into the same folder as the game's files and run it from there.
• It crashes or won't start: remember this is a test build. Make sure you have the latest s2x.exe from the official link, then ask in the S2x Discord.
• Server-hosting questions: the S2x Discord has a separate channel for dedicated servers, so ask there rather than in general support.

Getting help and reporting bugs

For install problems and general questions, use the support channels in the S2x Discord. Organised test sessions are run there as well.

If you hit a bug or crash you can reproduce, report it on the S2x GitHub issue tracker. That way it gets tracked properly. Search the existing issues first in case it has already been reported. A useful report includes:

• what went wrong, in a sentence or two
• the steps that make it happen again
• what you expected to happen, and what happened instead
• any error message, word for word
• screenshots, logs or crash dumps if you have them

Please don't

• Share or reupload S2x test builds. Point people to the official download link instead.
• Present a test build as a finished or official release.
