I am Russian and don’t know English very well. It’s difficult for me to find information in English, so I often use a translator, but it doesn’t always convey the meaning correctly. That’s why I decided to ask for help from those who might have the information I need. I don’t see anything wrong with asking experienced users for help.

and so I would be very grateful if, instead of mocking me, you would help me.

edited: I couldn’t find anyone in the Russian community who had tried to run the game via beamMP on Linux.
