Warhammer 40,000: Space Marine 2: Walkthrough & Boss Guide

This is an outline of the Space Marine 2 campaign and the Operations mode. It lists the campaign missions as given by Gfinity and the mechanics and story facts from Wikipedia. It does not provide per-mission tactics, weapon tier lists or difficulty-specific builds, which could not be verified. An earlier version of this page used invented “Chapter 1 to 8” headings that did not correspond to the game's missions; they have been replaced.

You can parry an enemy attack and follow with a gun strike, and some attacks can't be blocked and must be dodged. Armour absorbs damage; once it breaks, health drops when you are attacked. Executions regenerate armour, and health is restored with medkits or certain abilities. Downed characters bleed out for 30 seconds and can be revived by a teammate. We could not verify the old claim that a Fury meter grants brief invulnerability, so it has been removed.

You play Lieutenant Titus, an Ultramarines officer returning from the first game, and the campaign can be played with up to three players; otherwise AI controls Brother Chairon and Sergeant Gadriel. Gfinity lists: Prologue (introduces Titus as a Primaris Space Marine); 1. Skyfire (Kadaku, hold off a Tyranid assault so Imperial forces can escape); 2. Severance (help Nozick recover his data); 3. Machinus Divinitus (search a Tyranid-infested facility for Morias Leuze); 4. Servant of the Machine (Temple of Thassan, rescue Leuze); 5. Voidsong (deliver a message to Chapter Master Marneus Calgar); 6. Dawn's Descent (sneak in to stop Chaos forces using Project Aurora). Some sources count the missions differently.

The story follows Titus's Deathwatch mission to the Recidious System, Project Aurora and the Thousand Sons' attempt to exploit it. The Thousand Sons are a Traitor Legion dedicated to Tzeentch, and their elites are Rubric Marines and Sorcerers. Imurah, a Thousand Sons Sorcerer Lord, possesses the Astropath Neoma to block the Ultramarines' message to Calgar and manipulates the Mechanicus into building Project Aurora, then steals its artifact to open a rift to the Immaterium. Titus destroys the Power Source during the fight, killing Imurah.

Operations is the main cooperative mode, with missions that run parallel to the story; co-op supports 3 players. Gfinity lists six Operations: Inferno, Decapitation, Vox Liberatis, Reliquary, Fall of Atreus and Ballistic Engine (the Operations list may have grown since). Wikipedia lists seven classes: Tactical, Assault, Vanguard, Bulwark, Sniper, Heavy and Techmarine. Guides report that Heavy can use the Heavy Bolter, Multi-Melta and Heavy Plasma Incinerator but cannot use a melee weapon. Operations threat levels start at Minimal, Average, Substantial and Ruthless, and later patches reportedly added higher difficulties (a patch titled “Lethal Difficulty” exists), so Ruthless is no longer the top tier. Siege mode is an endless roguelike mode in which a team defends an Imperial fortification as long as possible. Competitive multiplayer supports 12 players in 6v6 battles.
