You should be able to follow everything below as they are all OS agnostic.
Also you MUST own a Steam copy for the other steps to work. If you have an archive copy I suggest checking out this cool dood who made a video guide to set up everything in this guide!

• Follow the warehouse guide in its entirety: https://wiki.aiwarehouse.xyz/en/tfc-wfc-pc-guide
  
• Obtain your "tfcwfc_pc.reg"
  
• [Optional] FPS tool: https://www.wsgf.org/phpBB3/download/file.php?id=2268
  
• [Optional] DLC mod: https://drive.google.com/file/d/1UQGA4clyO_GYD-0haYyWlrRiu7DK-FqP/view?usp=sharing (I and many other people will crash or not join your game with it if you don't have it installed. Plus as of CURRENT RELEASE you are objectively playing an inferior product without this.)

Extra notes about the DLC mod:

• PLEASE MAKE SURE YOUR COPY IS COMPLETELY FRESH AND UNMODDED.
  
• Open the rar with "Ark"
  
• Drag and drop the files from the rar into the game's root folder. Like so:

You will experience the following issues with WFC on Linux/Steam Deck:

• Unable to skip cutscenes
  
• 30FPS
  
• Connecting to multiplayer is slow (If you somehow launched the .reg file)

The next section will tell you how to fix these issues or deal with them. We'll be installing both GE-Proton-8-7 and Steam Tinker Launch

1. Download ProtonPlus on the discover store:
   
2. Open ProtonPlus and click on "add version":
   
3. Scroll down to GE-Proton8-9. You may need to click "load more" to see it.
   
4. Click the download button:
   

1. Scroll down until you see "SteamTinkerLaunch"
   
2. Click this download button
   

Now restart Steam.

1. Open Steam
   
2. Right click on Transformers War for Cybertron
   
3. Click on properties
   
4. Set your game compatibility to "Steam Tinker Launch" in the compatibility settings
5. Launch the game once and once a menu for Steam Tinker Launch shows up close it.
6. Go to "/home/(Your username here)/.config/steamtinkerlaunch/gamecfgs/id/"
   
7. Drag this config file into the folder: https://drive.google.com/file/d/1JC7echRj2rM6g0vt1eCv_oFpyhJgx-l6/view?usp=sharing
   
8. Edit line 38 to your the location of the FPS tool. (Note if you did not download the FPS tool change line 36's "1" to "0"):
   CUSTOMCMD="/(FILE PATH TO FPS TOOL)/TWFC_FOV__FPS_Tool.exe"
9. Go to "/home/(Your username here)/.config/steamtinkerlaunch/regs/"
   
10. Put your "tfcwfc_pc.reg" in this folder and rename it to "42650.reg"

No matter how much you mash A or Spacebar you can't seem to skip them!

1. Hit alt+enter to exit fullscreen mode.
   
2. Alt+tab to another window.
   
3. Alt+tab back into WFC.
   
4. Hit alt+enter to enter fullscreen mode.

If this sounds convoluted to you, it is. Valve please fix. (Or someone else since DXVK and Wine are both opensource so even YOU can fix this issue)

If you're primarily playing WFC in gaming mode like a normal person then just use window mode.

1. Settings
   
2. Graphics
   
3. Fullscreen -> Windowed (this is to prevent the game from going microscopic in gaming mode)
   
4. Switch the window to your FPS tool.

• When the game is launching in in game mode with this configuration you will need to wait for STL to get itself together. Give it 30 seconds and if it still hasn't launched, try relaunching it or restarting the Deck.
  
• After you set your frame rate on close the FPS tool IMMEDIATELY! The game won't properly close when that application is opened!
  
• Do not use Steam's exit option to close the game. You will need to click "Exit Game" from within WFC!

If something isn't working feel free to ping me here or in the warehouse discord server in #support (@robomike27). If you liked this guide, rate it up so people can see it instead of wandering around like a headless chicken looking for a way to play WFC on Deck.
