Mechanism: "Humility" Class Turret
Space Pirate defense system.

Beam-weapon variant of captured Federation turret. Evade its fire with quick movement. The Space Pirates copied captured Federation "Growler" turrets, but found the cannon unit inadequate. They replaced the Growler's weapon with a powerful galvanic accelerator cannon. The "Humility" turret packs a strong punch, but retains the Growler system's weaknesses. Fast targets can evade the crude targeting system, and the armor can't take much punishment.
