Pulse Cannon

The Pulse Cannon is a "variable" beam weapon used by Pirate Commandoes in Metroid Prime 2: Echoes. Pulse Cannon shots appear as blue energy projectiles and do minor damage to Samus. The Pulse Cannon is presumably a more advanced version of the Galvanic Accelerator Cannons. When Commandoes are taken by the Ing, their Pulse Cannons are augmented with dark energy.
