The Aqualung is a special breathing apparatus designed for divers. It is available in Hidden & Dangerous 2.
The aqualung is a compact breathing device carried on the back of a diver. Essentially comprising a tank of breathable air, face mask and diving fins, the aqualung is a newly developed piece of equipment suitable for underwater military use. The aqualung is best carried with a diving suit for long underwater missions. While the aqualung is excellent for underwater operations, it is completely unsuitable for land operations, as the fins continuously generate sound when walking, and creeping and running cannot be achieved. The aqualung is carried in place of a backpack.
