Quantum Assault Cannon

The Quantum Assault Cannon is the primary weapon used by the Space Pirate Troopers in Metroid Prime 2: Echoes. In terms of operation, it is extremely similar to the Galvanic Accelerator Cannon that is used by the Troopers in the original Metroid Prime. When activated, it fires short bursts of yellow-orange energy bolts. The Galactic Federation currently does not know how the Quantum Assault Cannon operates. It is possible that the weapons are based off of Samus' Power Beam, as their projectile appearances look nearly identical, as well as the fact that the Pirates had already reverse-engineered Samus' weaponry at the time that Metroid Prime occurred.
