G-type Rotolaser
this outdated weapon is similar to a Gatling Gun. It produced coherent bolts of energy like a modern blaster, but it does so via a rotating galven tube. The tube collects energy as is spins, and ejects a bolt whenever the galven pattern meets the barrel. The resulting bolts of energy are relatively low in power, since the galven tube spins rapidly and doesn't collect enough energy before it meets the barrel again.
