Quick Links
Warhammer 40,000: Space Marine 2has six co-op Operation missions for launch, taking players to multiple planets to face off against the forces of Chaos and the Tyranid swarm. Completing these Operations awards useful upgrade materials and Requisition Points, a currency used to upgrade your PvE Space Marine and acquire new cosmetics.
Fall of Atreus is the fifth Operation mission of the bunch, requiring you to charge up an ancient Astartes ship for one of Gadriel’s plans. Fight your way across a graveyard of enemies, help a vengeful Dreadnought, and escort a fusion battery across a battlefield to complete this fairly difficult mission. Before we talk tactics, let’s first cover what you’ll be facing.
Recommended Classes
Heavy, Sniper, Vanguard
Fall of Atreus spawns nothing butChaos enemies, notably Rubric Marines andTzaangors. These enemies are fairly durable and deal great damage, so you’ll want astrong add clear classin your ranks. TheHeavy with a Multi Meltacan obliterate these enemies with little issue,as can a Bulwark with a parry build.
For the Thousand Son units, you’ll want aSniperor aTacticalin your squad. Snipers can kill a Rubric Marine in 2-3Las Fusilshots, while the Tactical class has high uptime on the incredibleAuspex Scanability. Your last class slot is flexible. We suggest you bring aVanguardfor solid close-quarters damage and high mobility. It’ll make the last section a little easier.
Proceed To The Mechanicus Compound
Your squad’s goal is to reach the power plant inside the Mechanicus facility to kickstart the dormant ship. The start of the mission will take you down to a nearby excavation site.Tzaangorsand a few Rubric Marine packs will guard the path downright.Focus on the Tzaangors first, using a spare grenade or a Melta Gun to melt through them. If any of them carry a shield, use amelee heavy attackto break their guard.
The bottom of the structure will lead further down into the excavation site and nearby graveyard.This tunnel is a hotspot for Chaos Marines.If an enemy wave hasn’t spawned yet, it’ll most likely appear here. Stay at the back of the tunnel, picking off the Rubric Marines one by one.Make liberal use of grenadesto clear out the adds as quickly as possible. A restock crate is ahead, so don’t be afraid to dump all your ammo here.
Escort The Dreadnought
An Ultramarine Dreadnought will fight a small horde of Chaos units in the nearby graveyard. You’ll need toescort the Dreadnought across the graveyard, eliminating any Heretics you see. The Dreadnought is equipped with a flamer and minigun, which will melt through most Minoris enemies and leave Rubric Marines vulnerable to finishers.
Check the broken wall directly across from the Dreadnought’s spawn location for spare supplies.
After a short walk, the Dreadnought will plant itself outside the facility gates.Waves of Chaos will spawn around your squad, alternating between both sides of the gate and the nearby stairs. You’ll now start to seeTraitor Guardsmenin the ranks. They’ll die to a single shot of any weapon or even the weight of your Astartes, but beware of any snipers—if you see a blue line, dodge or react with a quick shot at the enemy.
Hold Until The Passage Is Clear
Now that the pathway is open, head inside the ancient structure. You’ll enter a spacious room where you mustdefend an excavation crane against waves of Chaos.Most enemies will spawn right next to the crane near the middle of the room, although Traitor Guardsmen will typically group up near the ramps that lead to the upper floor.Fight from the higher elevationif possible. Tons of Rubric Marines spawn during this part, so you’ll want some cover.
The crane sometimes stops functioning during this part. If this happens, head to the upper floor and look for a terminal you may interact with. Interacting with it will kickstart the generator and continue the encounter.
Jump down the hole once the debris is cleared and restock on ammo. The next section is going to spawn dozens of Chaos units in a fairly spacious arena, an underground Necron ruin that’s filled with debris.Tzaangorsshould be your priority since so many of them are down here. Further up the path will be even more Rubric Marines and, if they haven’t already spawned, a wave of Chaos enemies. Try to lure all the enemies into a single spot and fight them one at a time.
You’re almost to the facility. The Chaos enemies should have thinned out at this point. Make your way up the Imperial structure to reach the outskirts once again.A boss can spawn at thispoint; be careful. On most of our runs, a Helbrute usually appears during this part.
Make your way up the structure to find your old Dreadnought friend.Fight alongside the Dreadnought once moreuntil the entrance to the facility opens. Enemies will spawn around you and at the vantage points directly across. The platform directly across will always spawn Guardsmen, while the side platforms typically spawn Rubric Marines. Let the Dreadnought do most of the work here, finishing any enemies it damages. When you’re done, enter the facility.
Escort The Fusion Battery To The Power Plant
This is where the mission gets a little tricky.Your team needs to charge a fusion battery by leading it down a tramway.The catch is that the rails won’t be aligned in the correct path when you first start.Have at least one person split off from the group and head towards the railway controlslocated at the center of the platform. The other two Astartes should stick near the fusion battery and defend it from Chaos forces.
Controlling the rails is fairly simple. There are two sets of terminals you can interact with that will turn each set of rails by 90 degrees.Get the fusion battery onto a plate, then have your rail player rotate the fusion battery.You want the battery itself facing the front of where you’re going. If you see four terminals on the back, it’s facing the correct way. You simply need to coordinate with the terminal user to get the fusion battery docked into two chargers.
Of course, Chaos units will try to stop you throughout the process.On higher difficulties, you may simply ignore the battery and kill the Chaos units first.There will be nearly a dozen Rubric Marines per wave alongside anExtremis-class enemy, usually a Terminator. Killing all the enemies will give you a temporary lull in the action of roughly 60 seconds, enough time to safely charge the battery once. Kill another wave, then charge it again.
Your last objective is todock the battery next to the Atreus.This is a straight path you don’t need to manage, but a significant number of Rubric Marines will spawn during this part.An ammo crate can be found near the docking station, so stock up on ammo and give the Chaos everything you have. Dock the battery, defend it against two waves of enemies, and then start the generator to finish the mission.
