Booster Tank

The Booster Tank is an oxygen tank that can be used to give the player a speed boost in exchange for oxygen. It holds 90 seconds of oxygen on top of the player's normal 45 seconds.

Usage
The tank is equipped in the player's oxygen tank slot, as with all other oxygen tanks. While swimming, the player can press to boost the player's speed by more than double, at the cost of five oxygen per second of use, in addition to normal breathing costs. The Booster Tank's effect will stop once the oxygen in the tank is completely expended.
