1	Clear the Surveillance Zones
2	Connect Guide to the Ironheart excavation traces.
3	Manipulate the target to start Guide authorization.
4	Defend the area around the device.
5	Defeat Eterllick the Tracker

Clear the Surveillance Zones

Go to each of the Surveillance Zones and clear the area of hostiles. The enemies you'll encounter in this mission are tougher than usual and we highly advise that you bring a team of 4 people.

Connect Guide to the Ironheart Excavation Traces

As you head deep into the cavern, you'll encounter an orange terminal near a bunch of crystals on a wall. Interact with it to link Guide to the Ironheart Excavation Traces.

After this, you will have to clear another wave of enemies who will immediately come straight after you.

Manipulate the Device

Upon reaching a floating Crystal Device, interact with it so that Guide can begin the authorization process.

Defend the Area Around the Device

Stay within the vicinity of the device and defend it for 3 minutes against waves of enemies.

Defeat Eterllick the Tracker

Approach the altar containing a large Golden Device to summon the boss, Eterllick the Tracker. Defeat him 3 times to complete the mission.

How to Beat Eterllick the Tracker
Destroy the Three Spheres Break the Shield Barrier Avoid the Yellow Beam

Destroy the Three Spheres

Destroy the three spheres floating around Eterllick as you won't be able to deal damage to him with those circling around. Keep in mind that you will have to destroy each of the spheres within a short amount of time, otherwise they will respawn again one by one.

Break the Shield Barrier

Once his shields are up, shoot the little devices around it to break the shield.

Avoid the Yellow Beam

Each time you deplete Eterllick's health to zero, a yellow beam will appear around him and will explode. Make sure to keep your distance from him as soon you see it.
