Booster Tank

The Booster Tank is a special oxygen tank with the ability to trade oxygen for a speed boost. It has the same capacity as the High Capacity O₂ Tank at 90 units, for a total of 135 when it is equipped. Equipping one also incurs the same movement penalty of 0.47 m/s underwater and 0.61 m/s on the surface.

Usage
The Booster Tank is equipped in the paperdoll UI's oxygen tank slot. The player can press to boost swimming speed by more than double, at the cost of an additional five units of oxygen per second. The Booster Tank cannot be activated if the Oxygen in the tank is totally depleted. It can be used without limitation at the water's surface, making it a very fast way of travelling.
