Space Pirate technology with weak thermal shielding

Plasma Artillery Cannons are mounted weapons used by Elite Pirates to launch disruptive projectiles in Metroid Prime.

Unlike other pieces of technology commonly used by Space Pirates, the Plasma Artillery Cannons used by Elite Pirates were apparently not of Space Pirate origin. They were stolen from a warehouse belonging to a military division known as the Egenoid Star Marines.[1] Further inspection of these weapons revealed that, though they were fully functional, inferior thermal shielding gives them a high heat signature, which can be targeted using Thermal Imaging.[2] The Cannons used by Elite Pirates are connected to their Energy-siphon Systems to augment performance, but the resulting explosive chain reaction that occurs if the Cannon is destroyed incurs severe damage to the wearer.[3]

The Omega Pirate variation, called the Plasma Incendiary Launcher, shares none of the weaknesses of the Plasma Artillery Cannons.

  1. "A shipment of military-grade Plasma Artillery Cannons is en route to Tallon IV. The Egenoid Star Marines we 'acquired' them from were letting them sit in a warehouse. Our Elite Pirates, on the other hand, will put them to good use very soon." —Scan Data (Metroid Prime)
  2. "Evaluation of Plasma Artillery Cannons is complete. The weapons are fully functional, but a flaw has been discovered. Subpar thermal shielding gives them a high heat signature. This could make them easier to target for enemies with enhanced vision capabilities." —Scan Data (Metroid Prime)
  3. 3.0 3.1 "Plasma Artillery Cannon. Unit has extreme thermal signature due to lack of shielding. Cannon connected to energy-siphon systems to augment performance. Avoid Beam weapon fire when energy-siphon unit is active." —Scan Data (Metroid Prime)
