Allied forces assault a quaint little farm on the outskirts of Amberg, Germany. The farm is being used as a supply dump and Flak88 firing position by those stinkin' nazis! There is plenty of open, rolling field to move from cover to cover. There are also tall buildings on either end of the field for sniping, so watch your backs! The overall area isn't too large and should provide for a nice paced fight, IMO.
