I hear the bell snap like a warning at dawn. You’re on the ledge, Tyranids clawing for purchase, and the gate is already halfway closed. For a second the Cathedral feels like an iron maw.
I’ve run Disruption enough times to know where it trips most players up; I’ll walk you through the route I trust, the weak points you can pressure, and the moments where hesitation costs you the mission. Read this while the patch notes are hot and the meta is settling—you’ll move faster, shoot cleaner, and finish the operation without leaving teammates behind.
Warhammer 40K: Space Marine 2 Disruption Operation walkthrough
A ruined cathedral draws a crowd of looters in daylight; in combat it becomes a choke point that kills slow plans. The Disruption operation on Avarax breaks down into clear objectives you can treat as checkpoints: reach the Cadians, hold the line until gates close, protect generators, rendezvous with the Redemptor Dreadnought, push to the Cathedral, set charges, and hold until detonation.
- Reach the Cadian forces: Meet Commander Otel after a short skirmish with Thousand Sons and Tyranids. Major Kevar is gone—Otel runs the 22nd Company now—so move fast and clear pockets of cultists to consolidate the defensive line.
- Hold position until the gates are ready to close: You’ll be shooting from ledges and walkways. Tyranids will try to leap up for melee; prioritize ranged flayers first and fall back to the generators’ sightlines when swarms arrive.
- Defend the generators: The Zeta sector spawns a second wave—take a quick stair sweep east to thin numbers, then return to the main power nodes. Gargoyles hit the generator near the main gate; drop them before they break the armor.
- Rendezvous with the Dreadnought: A Redemptor (Brother Valtus) lands to break the siege. Use elevators and canals to flank toward his position. Expect a Helbrute on the way; Cadian squads help but don’t rely on them to carry the fight.
- Follow the Dreadnought to the Cathedral: Clear mixed patrols and underground passages. Valtus will create paths—stick to his advance and mop up archers and sorcerers before they pin you down.
- Provide suppressive fire: While Valtus works the arcane barrier, kill Thousand Sons snipers first, then soften armor oracles preventing the Dreadnought from reaching the bridge. Heavy weapons and headshots matter here.
- Plant the explosives and hold: Grab charges from fallen soldiers, plant markers on the pillar beside the rift and the pillar above. After you place them, fall back to the Dreadnought and hold the Cathedral until the countdown ends.
Rendezvous with the Dreadnought
A stalled convoy feels exposed in the rain; on Avarax the canal route is that exposed lane. Move toward Valtus by hugging cover, clear the Helbrute with focused fire, and don’t let dozens of small enemies split your attention while the big threats close.
- Use the canal approach to flank—Cadians will be nearby but unreliable. Your aim matters more than theirs here.
- When you reach Valtus, clear the immediate area so the Dreadnought can progress; if he gets pinned, you’ll be left to fight a Heldrake and energy sorcerers alone.
- Valtus can chew through heavy air threats; stay under his arc to avoid the worst of the fire and preserve ammo.
How do I complete the Disruption operation in Space Marine 2?
You complete it by treating each phase like a mini-objective rather than one long slog. Clear snipers first, protect generators second, and always have an exit route when planting charges. Remember: hold the Cathedral perimeter until the timer ends—if enemies breach the egress point, the detonation can fail.
Where is the Disruption operation located?
It’s set on Avarax at the Ecclesiarchy Cathedral sector. Expect tight vertical spaces, canal approaches, and defensive positions where line-of-sight beats roaming speed. This map rewards players who control choke points and move with the Dreadnought’s advance.
Planting explosives and the final hold
A countdown timer is one of the clearest signals of risk in any operation; when you see it, panic spreads faster than bullets. Grab the charges from fallen soldiers, place the two objective-marked explosives around the rift pillars, then fall back to the Dreadnought and hold the Cathedral mouth.
- Target priorities while planting: Kill long-range casters and snipers first. Sorcerers will buff cultists—remove them to stop the spawn acceleration.
- Defensive posture: Use barricades and choke points. Keep angles narrow and force the enemy into your fire. If you play quietly, the Dreadnought eats heavy targets while you mop up light infantry.
- When the countdown starts: Cover exits. Every heretic that escapes adds time and risks mission failure. Hold tight for the cinematic finish.
How do I defend the generators and set explosives?
Hold high ground, kill flyers before they break the generator shields, and clear stairwells leading to the Zeta sector. When planting, use cover to bait attackers into narrow paths; it’s easier to predict movement in those corridors. If you’re on PC, tools like GeForce Experience or Steam’s overlay help capture runs for later review if a tactic goes wrong.
I’ve seen players rush the charges and lose the perimeter; I’ve also seen teams stall on a single generator until the Cathedral gate opens and everything cascades. Move with purpose, shoot the long-range threats first, and treat Valtus as a moving fortress—he clears air and heavy armor so you can do the dirty work on foot. Valtus moves through the street like a bulldozer through masonry.
Arch-Deacon Zoenia’s fate is a small story beat that matters emotionally: pull her out and you get a different beat in the narrative, leave her and the scene plays darker. What would you choose when the clock is ticking and the Cathedral is about to come down?
