The M-45 is a default weapon of the Heavy class. As a default weapon, it shares the same statistics as the other default weapons for the Heavy class. It also means that it is unable to unlock or equip any weapon modifications, which limits the weapon's adaptability and overall potential.
The M-45 is able to fire a plethora of blaster bolts at a high rate of fire before overheating. This means the M-45 can suppress an area or target with more shots and for a longer period than most other blasters. However, the blaster has a high spread which limits its accuracy and capability at at longer ranges.
