Note that this is a very early stage so formations are not perfect yet. You will see a fighting sequence between several hundred battleships in tight formation.
Featured ships:
Imperial Battleship 'Neustadt' class.
Imperial command ship 'Ashgrimm' class.
Imperial Carrier 'Wotan' class.
And of course the imperial Strikecraft 'Walkuere'.
Expect some Free Planets Alliance ships soon !
