Aqualung

Aqualung is a torso augmentation in ''Deus Ex. ''It is a nanotechnological augmentation that increases oxygen duration when underwater.

This augmentation is installed from the augmentation canister that also includes Environmental Resistance. Since there are three torso slots and more than one copy of this canister, it is possible to acquire both Aqualung and Environmental Resistance by using a second copy of the canister.

Description
Soda lime exostructures imbedded in the alveoli of the lungs convert CO2 to O2, extending the time an agent can remain underwater.
 * TECH ONE: Lung capacity is increased slightly.
 * TECH TWO: Lung capacity is increased moderately.
 * TECH THREE: Lung capacity is extended significantly.
 * TECH FOUR: An agent can stay underwater indefinitely.

Effects
Aqualung is an active augmentation that consumes bioelectric energy at 10 units/minute.

When activated, this augmentation increases the base oxygen duration as listed below. Oxygen duration can be further extended by the multiplier from the swimming skill. Since the swimming skill provides an oxygen duration multiplier of 2.5 at the master level, an oxygen duration of 600 seconds (10 minutes) can be attained by the combination of master level swimming and tech 4 Aqualung.
