The Hive Mind is a multi-part boss consisting of a central core and several smaller, interconnected segments. The core is often invulnerable until you destroy its segments. Each segment might have a different attack pattern. Focus on destroying the segments one by one, then unleash all your damage on the exposed core. This boss often fills the screen with projectiles or small enemies, so crowd control and area damage are highly beneficial. Maintain situational awareness and prioritize targets to efficiently dismantle the Hive Mind.
