The particle beam cannon is a powerful weapon used by the Heavy Dog and Blue Falcon during the boss battles with them in Shadow the Hedgehog. The particle beam cannon sends dangerous blue waves of energy across the ground.
The particle beam cannon needs charging and once it's charged it shoots several horizontal electric shock waves in circle which can cause damage. To dodge the waves the player has too change the platform where Shadow is standing when the canon is charged. Sometimes the cannon is not fired until Shadow jumps to another platform or the G.U.N vehicle gets near Shadow.
