Arc Turbines are formidable mechanical enemies in Arc Raiders that descend from the sky and pose a significant challenge to players. Defeating them yields valuable Turbine Compressor materials, necessary for the Avian Alarm project and crafting the Powered Descender item. Players can also obtain Turbine Compressors from Arc Couriers, which are less dangerous and spawn more frequently in areas like the swamp on Dam Battlegrounds or during the Electromagnetic Storm map condition. To effectively engage an Arc Turbine, players should wait for it to land before attacking, use Deadlines for cover, or shoot from a distance with a Hullcracker, targeting the spinning yellow cylinders at its core. Shooting while the Turbine is airborne will provoke a lightning attack.
