While launching game option at the start, it just gives error "The game is not set up properly. Please reinstall.", for all of them, but was able to see setup menu, no changes in them made the game to run, however. When I tried to start Fight for Freedom, it said "This is a mission-pack version of Hidden of Dangerous. Please install original version of Hidden and Dangerous in order to continue". Tried to change Proton version through Steam settings, no luck. "Hidden of Dangerous" is not a mistake of mine, by the way. 😅
