Proceed to the Mechanicus Compound 1

Space Marine 2 - Proceed to the Mechanicus Compound

At the starting point, just proceed forward while following the objective marker with your teammates. You will encounter Minoris and Majoris enemies as you proceed downwards. Team up with your party to defeat these enemies.

You will eventually stop at an obstruction. Lift it to proceed further until you reach a graveyard where your next objective is located.

Follow the Dreadnought

Space Marine 2 - Follow the Dreadnought

At the graveyard, you will meet the Dreadnought and your objective here is to follow it. Fight enemies(mostly Minoris and Majoris) that are stopping its march. Do not worry as the Dreadnought is equipped with a flamethrower and a minigun to help fend itself against Heretics.

Eventually the Dreadnought will go to a gate and will open it so you can proceed.

Clear the Passage

Space Marine 2 - Clear the Passage

Enter the building at the other side of the gate and interact with the objective. Your mission here is to hold until the passage is clear by protecting the excavation crane.

Build the meter up to 100% to complete this objective.

Activate the Enginseers' Consoles

Space Marine 2 - Activate the Enginseers

If you fail to protect the excavation crane, you will need to activate the two Enginseer's Consoles in time. Once you activate one of the consoles, you would need to go to the other console to activate it before the timer runs out.

Proceed to the Mechanicus Compound 2

Keep descending downwards by following the objective marker while defeating more enemies on the way.

Repel the Assault

Space Marine 2 - Repel the Assault

Your next objective will be repelling the enemies by defeating them. After defeating them, your next goal is to talk to the Tech-Priests.

Speak with the Tech-Priests

Just keep following the objectives and you'll eventually encounter the Tech-Priests. After that, open the gate to get to your next objective.

Escort the Fusion Battery to the Power Plant

Space Marine 2 - Escort the Fusion Battery to the Power Plant

Interact with the console to start moving the fusion battery on the tramway. Have one of your teammates get to the railway controls (located at the center of the platform) to adjust the path of the battery.

Meanwhile, have two members of your team protect the battery while it is moving. It is recommended to kill the enemies first to have an easier time adjusting the path and guiding the battery before new enemies spawn.

Escort the Fusion Battery to the Battle Barge

Space Marine 2 - Escort the Fusion Battery to the Battle Barge

Your goal here is similar to the previous one. You will need to adjust the tracks and guide the battery to the battle barge this time which is the large structure in the middle of the map. Use the railway controls to change the path of the battery and guide it towards its goal.

Defeat the enemies first before moving the battery.

Hold Until the Engines Charge

Space Marine 2 - Hold Until the Engines Charge

Upon reaching its destination, it will charge the engines and you have to defend it from incoming enemies. There will be a percentage bar at the top right where it need to reach 100% to complete the objective.
