Talk to Chaplain

Follow the objective marker to get to where Chaplain is. Talk to him until you get the Why Is It Always You Three? achievement. Afterwards, proceed to the launch bay by following the objective.

Hit 10 Objects to Unlock Achievement

At the start of this mission, you will be flying forward through the space while avoiding debris on the way. Be careful of the debris as you'll take damage if you hit one.

But you can also take this opportunity to unlock the achievement, My Face Is My Shield, by hitting 10 debris.

Fight Your Way to the Enemy Vessel

After a cutscene, you will land down on Demerium and will be greeted by swarms of enemies. Fight your way through and follow the objective marker until you see a console panel that will open a door.

On the other side will be more enemies. They are positioned on different platform-like areas so be careful when you jump from one place to another. At the end you will have to destroy the Altar of Corruption.

Advance to the Cathedral

After destroying the Altar, a platform will slowly descend. Go towards it to get to your next objective. Just follow the objective marker and then interact with the transmitter inside the cathedral.

Hold Until the Battle Barge Has Target Lock

After interacting with the transmitter, a series of battles will begin. Keep defeating the enemies that will come. A cutscene will then play once this objective is complete.

Advance to the Mechanicus Facility

After the cutscene, keep following the objective marker while fighting enemies on the way. Destroy the Altar of Corruption once you see one and then proceed forward.

Keep defeating enemies along the way until you reach your objective.

Investigate the Dig Site

As usual, follow the objective marker and fight enemies along the way again. A path will open to the tunnel after defeating the first set of enemies.

Proceed onwards and then interact with the machine at the end to get decontaminated. After the loading screen, go follow the objective marker.

Explore the Ruins

Lift the pillar-like thing to proceed and continue onwards where you will encounter more enemies. Just do the usual: defeat all enemies until a new set of dialogue appears.

Continue onwards and then push the thing blocking the way. Reach the are with the blue aura and you will have to fight again. Proceed after defeating them and do the same as you always do during this mission: defeat enemies along the way.

You will reach a blue passageway and a room with enemies. Defeat the enemies so you can destroy the Altar of Corruption.

Hold Until the Elevator Arrives

Proceed forward again until you reach an elevator. Activate the elevator and wait for it to arrive while holding off enemies. After defeating all enemies, descend down using the elevator.

Advance to Aurora

Follow the objective and defeat the enemies attacking once more while proceeding. You will eventually reach an area where there are stunned enemies.

Defeat the Helbrute

A cutscene will play out once you reach the room with the stunned enemies. After the cutscene, a Helbrute will show up. Defeat the Helbrute to finish the mission.
