Download the file dinput8.dll with the latest version of the mod. It is obligatory to download the latest version, because it does not want to work with others Google Drive Link[drive.google.com]
This file restores locked commands to the developer. The file must be inserted into the root of the game. Properties -> Open local files


Next go to Library -> find Doom -> Properties -> Compatibility tab -> select Proton Experimental (you can try with other versions, but after 3 failed attempts - this version was successful). This step is necessary so that we can set the startup settings for the game. Otherwise the file dinput8.dll will not pull up and the commands will not work.

Go to Controller settings and on the back keys L4-L5, R4-R5 set the keys from keyboard:

• L4 - Button Control
  
• R4 - Button V

I additionally remove the start screen saver to save time on the key.

Firstly, when you select Network Game -> Training Arena, you should see the Trials tab appear. You can select one of the trials to track (e.g. number of kills).
