the beasty seen here is grown deep within liberator class combat walkers. vats of salt water are used to grow a seashell like organism that breaks down its meals of iron rich ore mixed with decaying matter. into a series of organs that contain a highly explosve chemical compound and an iron shell grown within its central body cavity. when fully grown the creature is mounted on a rocket and fired at the enemy, on contact with a solid surface a powerful muscle contraction forces the spike into the target while the explosives are ignited causing immense destructive force. it is highly effective on most enemy targets when fired in swarms and has a severe effect on enemy moral due to the piercing wail of the rockets in flight.
