RE: Kriegsmarine released
It's the same engine as Wolfpack (though the graphics are substantially improved.)
There's a BIT more to the Bismarck Campaign than there was in WP, but it's essentially several battles strung together, with player choices dictating exactly what battle you get into. There is no strategic layer to the game, if that's what you are looking for.
The Random Campaign is that you'll end up in one of 10 randomly chosen battles, which gives you the opportunity to run a battle without full knowledge of what's out there.
