Aces of the Deep Expansion Disk

An expansion package for either the floppy or CD versions of Aces of the Deep
adds brand new missions, areas and a special prototype XXI U-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 buoyancy gauges which allows a quicker
reading of your depth in the ocean. Most amazing 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.
