The laser shotgun functions similarly to that of the Plasma Discharger in that they both use 'batteries' as ammunition. (Even though in the laser shotgun's case, it's more of a microgenerator than a battery.) What makes the laser shotgun stand out is it's gaussian nature. The "pump" of the shotgun is actually a large round magnet, which, when pumped, pulls the next battery forward. The magnetic interference of the pulling causes the battery to eject several green lasers. The laser shotgun isn't deemed stable enough for military usage, but is commonly used among most Nimbus Killsquad troops.
