It is evident that Noland had somehow managed to repair the weapon by scavenging whatever parts he could find. The weapon fires blue bolts of plasma. Although it is a Plasma Caster, it appears to fire in a similar manner to human firearms. This may be due to repairs performed by Noland, or the possibility that Noland himself completely constructed the object himself completely out of scavenged parts.
On the Game Preserve Planet, Noland used his Plasma Caster to kill the River Ghost chasing Edwin with a single shot in 2010.
