The Sonic Eruptor is a weapon manufactured by Grummel Net Industries in A Crack in Time and Full Frontal Assault. The weapon is a machine which holds a frog-like creature known as a Xenegote, which damages enemies by emitting a soundwave (its mating call). The strength and radius of this soundwave is determined by how large its cheeks puff out before firing. The Sonic Eruptor can be upgraded to the Super Sonic Eruptor in A Crack in Time with use, and to the Alpha Sonic Eruptor with use in Full Frontal Assault.
