Is there way to pass custom command line parameters to UE4 game (build)? I need easy way to pass some parameters from game launcher (fullscreen, language, etc.)

Yes - you can use FParse::Value() to read a value from the command line, for example:

int32 TheValueIWant = INDEX_NONE;
if (FParse::Value(FCommandLine::Get(), TEXT("TheValueIWant="), TheValueIWant) == false)
{
	TheValueIWant = DefaultValue;
}

…will attempt to find a value after “TheValueIWant=” in your command line, and assign the found value to your local variable, and falls back to a default you’ve defined somewhere if it can’t find the command line argument.
