Legion's unique Overcharged Metal Extractor produces 2x the metal as other factions' normal extractors, while costing 30 E/s in upkeep. It's generally not worth it for standard value metal spots, but it generates massive returns on spots that produce more metal. These spots tend to be in riskier spots closer to the front lines, though, so they are even more valuable targets to defend (or attack).

It also increases metal storage by 150.
