Rebreather

The Rebreather is an unlockable Rifle available for the Stormtrooper.

Design
The Rebreather is based off the APS Underwater Rifle.

Overview
The Rebreather is unlockable by completing the Into The Sea achievement pack. This involves killing enemies in and around the water.

The Rebreather has a much higher chance to crit underwater than any other rifle, but it cannot crit while out of the water. This makes it a very good weapon for fighting enemies underwater, but only then.
