Tutorial/Watch Out for Bullets!

According to Auni, in order to stop the hazardous device's attacks, you must first remove its "energy core" — a Kuuvahki Relay Mechanism.
Approach the hazardous device carefully and attract the Kuuvahki Relay Mechanism to shut it down.

Someone appears to have set up countermeasures near the hazardous device. Take shelter from the red Unipolar Projectiles by hiding behind the Unipolar Barriers.

Not all the devices that generate Unipolar Barriers are in working order. Throw a Kuuvahki Relay Mechanism on an inactive device to restore its functionality.
