The beam is a short blast of red energy. The beam is no longer used by Pirate Troopers in Metroid Prime 2: Echoes, as the Pirates upgraded their beam systems to a supposedly more efficient weapon. Instead, they equip their Turrets with Galvanic Accelerator Cannons, making them more powerful. Pirate Commandoes are armed with Pulse Cannons. In Metroid Prime 3: Corruption, the beam has been completely abandoned in favour of new beams powered by Phazon. The Galvanic Accelerator Cannon is absent in Metroid Prime Pinball; instead, the Pirates use Missiles.
