An expansion package for either the floppy or CD versions of Aces of the Deep adds brand new missions, areas and a special prototype XXIU-boat submarine.
Some of the more interesting features are the six new historical missions as well as the ability to enter (but possibly not leave due to currents) the Mediterranean Sea. Also included are boyancy guages which allows a quicker reading of your depth in the ocean. Most amazingly is the prototype Type XXI U-boat, which includes sonar and radar abilities as well as two kinds of torpedo types for it's exclusive use.
