Manufactured by Intergalactic Arms and used by large fighterships built by Quincy Station. The quake bomb is one the most advanced weapon ever made. It, when detonated, releases a mixture of pure ion particles and negative charged plasma. It destroys anything in it's path when sending out a ray of mixed particles in every direction. It can penetrate both ion and plasma shields.
It is similar to Siesmic charges on the movie series Star Wars.
