The Metaphase Field is a base shield that provides equivalent protection to all types of weapons, obtainable by defeating level 20-27 rebel cargo fleets or level 27-45 level VEGA cargo fleets. This means that the fields will take the same amount of damage from energy weapons as they would from explosive and projectile weapons. In the past, Metaphase only resisted 80% of incoming damage, but this has since been raised to the full 90%.
Metaphase Shields have rather high shield energy. At level III, the shield amount surpasses that of a level V Shockwave field, and just below a level V Spectral Field. They are the most ideal shields to equip on combat modules in any scenario.
