Subaqua blaster

The Subaqua blaster was an arm-mounted laser weapon designed to operate while fully submerged in water. While it did have a limited round capacity compared to standard blasters, its usefulness in aquatic environments was unmatched. It used the ambient water as coolant, which meant repeated use in a standard atmosphere would quickly cause the weapon to overheat and explode. Additionally, the bolts fired in air were substantially less powerful, and the range of the weapon was halved.
