Boss tips
Mobalytics characterizes Mimicron as a melee boss and recommends shock and corrosive weapons. This is third-party guide advice, not an official developer recommendation or a claim based on independently verified testing. Bring weapons using those elements if they suit your loadout, and be ready to manage close-range pressure.
