How to remove the unnecessary long sound at the beginning of a battle.

I haven't tried to remove the sounds, although sometimes I would like to save a few seconds. But here's a tip from FizMiG: how to skip the intro when launching the game. You need to add the /i0 key to the shortcut properties, in the launch string, for example: D:\Games\HeroesMM3\h3wog.exe /i0
And the /s0 key disables music and sound.
