A shoulder-mounted blaster refers to a kind of blaster that was part of the battle armor worn by Cydon Prax in the Clone Wars. This type of blaster demanded a different skillset to use compared to other blasters, and it delivered much more power than the heavy blaster pistol Prax also carried. The Parwan bounty hunter named Derrown, who was nicknamed "the Exterminator," was known to use a shoulder-mounted blaster as well.
