Achtung Panzer intro movie as a background for the game's main menu. Make sure you are running no other mod to be able to see this custom background.
Installation:
Place the achtung-panzer-mainmenu.pak file to your .../Blitzkrieg/Run/data folder and run the game.
that mod is sooo awesome , been playing blitzkrieg for over a decade now and never gets boring :)
