1 Destroy the alarms to disarm the nuclear reactor's self-destruct.
2 Occupy the area to capture the nuclear reactor's cooling system.
3 Defeat Alzaroke the Loyalist
4 Activate the terminal to obtain Ironheart Refining information.

Destroy the Vulgus Sensor Alarm

The First Descendant - Unknown Laboratory Alarm

Fight your way through the laboratory until you reach the Vulgus Sensor Alarm and destroy it. After reducing a quarter of its HP, it will become immune to damage. You will have to kill all enemies that will spawn nearby to remove their immunity effect.

Take Control of the Reactor's Cooling System

The First Descendant - Capture the Reactor

Next, make your way to the Nuclear Reactor's Cooling System and occupy it by staying inside the circle for 3 minutes. At this point, waves of enemies will continuously spawn, so be prepared to defend yourself. Once the timer is up, activate the terminal nearby to take control of the cooling system.

Defeat Alzaroke the Loyalist

The First Descendant - Alzaroke the Loyalist

Leave the main laboratory complex and head outside. Here, you'll have to defeat Alzaroke the Loyalist, the mission's boss who mainly uses a shotgun to damage you from long-range.

How to Beat Alzaroke the Loyalist

Activate the Terminal

The First Descendant - Activate the Terminal After Beating Alzaroke

Once Alzaroke has been dealt with, approach the terminal on the landing pad and activate it to complete the mission.

Defeat the Enemies Linked to Him

The First Descendant - Alzaroke Linked Minions

Alzaroke will usually spawn several enemies connected to him via a white line and will become immune to damage. Make sure to kill all of the minions linked to him first to remove his immunity before targeting Alzaroke himself.

Utilize Cover Around the Area

Since Alzaroke is a range-type boss, you can make use of the structures and containers spread all over the area as a form of protection from his projectiles.

Avoid the Barrage Attack

The First Descendant - Alzaroke Barrage Attack

The Barrage attack is a deadly move that will completely deplete your shields if you get caught in it. Thankfully, you can anticipate this early and avoid it once you see Alzaroke charging up his gun.
