Most advice floating around still treats Warhammer 40,000: Space Marine 2 as a single progression ladder, telling new players to grind Operations until their gear feels comfortable before ever touching Eternal War. That advice was already shaky before patch 12 added a seventh class, and it falls apart once you realize PvE and PvP don’t even share a currency. This is about picking the right grind for what you actually want out of the game, not which mode is objectively better.
TL;DR
- Armoury Data – the only currency that unlocks Relic-tier weapon variants – drops exclusively in Operations and Siege. PvP gives none.
- Eternal War runs on Veterancy Level, Requisition, and Accolades – a completely separate track that never touches your PvE gear.
- The Techmarine class (added in patch 12) plays in Operations, Siege, and PvP, but is not available in the campaign.
- Want Relic gear and weapon tiers? Start in PvE. Want rank and Eternal War cosmetics? Start in PvP.
- Clearing every class’s Trials in the Armouring Hall is a one-time chunk of free Armoury Data worth doing before you commit to either grind.
The Short Answer
If your goal is gear score, weapon tiers, or Relic-rarity Armoury Data, start in PvE. Neither the campaign nor PvP awards any Armoury Data, so Operations and Siege are the only two modes that move that needle at all.
If your goal is PvP rank, Accolades, or Eternal War-exclusive cosmetics, PvP first is the correct call, because progress made in PvE does not carry over to PvP, as each has its own separate progression system. Grinding Operations first buys you nothing toward your Eternal War veterancy.
The one wrinkle: the Techmarine, added in Space Marine 2’s update 12.0, introducing the new Techmarine class, more PvE content, a weapon, a new map, and so much more, is playable in Operations, Siege and Eternal War, but not the campaign. If you’re rolling it fresh, you’ll need at least one PvE mode in rotation regardless of which grind you prioritize.
Armoury Data Is the Reason PvE Comes First
Armoury Data is a single currency across three rarities – Master-Crafted, Artificer, and Relic – and it is what actually unlocks higher weapon tiers. Armoury Data comes from two PvE modes: Operations and Siege. In Operations it drops from a hidden Servo Skull or from killing a Terminus-level boss that can attack at random. The Terminus-tier bosses you’re hunting are the Carnifex and Neurothrope on the Tyranid side and the Helbrute against Chaos.
Why Operations Punishes Greed
The catch is extraction. You have to actually survive the mission for any of it to count, which is the kind of detail that ruins runs for players who get cocky at the end.
If your squad wipes before extraction, you lose the Servo Skull and any Terminus drops from that run – the drop only banks once the mission is marked complete.
For a full breakdown of which difficulty tiers yield which rarity and how to route missions efficiently, the Armoury Data farming guide covers the actual routing in more depth than this one needs to.
Siege’s Fixed Payout Schedule
Siege doesn’t gamble on random drops the way Operations does. Instead it pays on a schedule tied directly to which wave you clear and which difficulty you’re running.
Siege pays out on a fixed schedule instead of a random one — clearing Wave 10 grants three Master-Crafted on Normal (Artificer on Hard), and Wave 20 grants three Artificer on Normal (Relic on Hard). That predictability is what makes Siege the better choice once you know exactly which rarity you’re chasing, and it’s the mode I’d point anyone toward if the goal is Relic gear on a deadline. Difficulty also gates the ceiling outright: Minimal and Average cap at green Master-Crafted, Substantial opens purple Artificer, and Ruthless is where Relic actually starts dropping, with Absolute pushing volume higher through denser Terminus spawns.
One more free chunk of currency exists outside both loops: achieving an A-rank in training Trials gets you one Master-Crafted Armoury Data per Trial; every class has three Trials in the Armouring Hall, so a full sweep across the roster is a one-off chunk of Master-Crafted Data without entering a mission — Trials cannot be repeated for more. Do this once per class and move on; there’s no reason to leave it sitting unclaimed.
| Wave Cleared | Normal Reward | Hard Reward |
|---|---|---|
| Wave 10 | 3x Master-Crafted | 3x Artificer |
| Wave 20 | 3x Artificer | 3x Relic |
What Eternal War Actually Rewards
Eternal War isn’t a smaller version of the PvE loop with players instead of AI – it’s a different game economically. In Eternal War, Space Marine 2’s PVP mode, the skill trees are gone and weapons and equipment are unlocked from level 1, while Veterancy Level mainly drives cosmetic rewards, Accolades, and Ordeals. No Requisition Points spent on perks, no Armoury Data spent on tiers – just XP and match performance.
The Modes You’ll Actually Queue Into
Two teams of 6 players are tasked with completing objectives (which change depending on the game mode) while stopping the other team from completing those objectives. Eternal War began with three classic 6v6 modes, then Patch 10 added Helbrute Onslaught. If a guide you’re reading only lists three modes, it’s outdated.
- Annihilation – team deathmatch to 50 points
- Seize Ground
- Capture & Control
- Helbrute Onslaught – both teams play as heretics
Veterancy, Accolades, and Ordeals
Think of PvP rewards as goals, not power gates. Your weapons and equipment are open from level 1, while Accolades, Heroic items, armour pieces, and Ordeals give you reasons to keep playing. This is honestly the part I appreciate most about Eternal War’s design – a fresh account isn’t stuck running a starter loadout against players three hundred hours deep. Rank chases cosmetics, not viability.
YouTube clips will show a maxed Veterancy Bulwark soloing a whole point, and it looks like the class is mandatory. It isn’t – each team is limited to two of a particular class, so you can’t stack six of them even if you wanted to, and objective play beats kill-farming in every mode except Annihilation.
Match the Grind to Your Goal
Goal: Relic Weapons and Full Weapon Tiers
PvE, no contest. Run Siege on Ruthless once your squad can consistently reach Wave 20, since that’s the guaranteed Relic payout rather than a coin-flip Servo Skull spawn in Operations.
Goal: PvP Rank, Accolades and Heretic Cosmetics
Skip Operations entirely if this is the only thing you want – it contributes zero XP toward your Eternal War veterancy. Queue Eternal War directly and rotate loadouts by map, since nothing is locked behind a grind you haven’t done.
Goal: Trying the New Techmarine Class
You’ll need at least one PvE session regardless, since the class is locked out of the campaign entirely. Clear its three Trials in the Armouring Hall first for a free Master-Crafted bump, then decide whether you want it for Servo-Gun crowd control in Operations or for reactivating Tarantula Sentry Guns in Siege and PvP.
Common Mistakes to Avoid
The Data Refinement system trips people up constantly. It only converts upward – three of a lower rarity into one of the next tier – and never the other direction, so hoarding a stack of Master-Crafted instead of refining it just wastes bag space once you’re swimming in Artificer.
Hard class restrictions catch new players mid-Operation more often than they’d admit: Bulwark cannot equip a primary weapon and Heavy cannot equip a melee weapon at all. Lock into either class expecting a normal loadout and you’ll be stuck rebuilding your kit mid-mission.
The other recurring mistake is chasing the Techmarine into the campaign expecting to use it there. It simply isn’t an option – Operations, Siege, and Eternal War only.
PvE vs PvP: Quick Comparison
PvE has the gear, PvP has the rank – and neither grind refunds you a single point of the other’s currency.
| Mode | Main Currency | Gear Payoff | Class Availability |
|---|---|---|---|
| Operations / Siege (PvE) | Armoury Data, Requisition | Weapon tiers, Relic gear | All 7 classes |
| Eternal War (PvP) | XP, Veterancy, Accolades | Cosmetics, rank, Heroic items | All 7 classes, 2 per team cap |
Short on Play Time?
Not everyone has hours to burn on a full Siege descent or a string of Eternal War matches every night. If your sessions are short, prioritize based on what actually compounds fastest per hour played.
- Run Trials once across all seven classes for the free Master-Crafted bump before anything else
- Stick to Siege runs targeting Wave 10 extraction rather than pushing for Wave 20 if your squad isn’t consistent
- Play Eternal War in short bursts – Veterancy XP doesn’t require full-length sessions to add up
- Skip the campaign for progression purposes entirely; it contributes to neither currency track
Neither grind rewards marathon sessions specifically – a scattered 30 minutes here and there across a week adds up the same as one long sitting, since both Armoury Data and Veterancy XP are session-agnostic.
FAQ
Does PvE gear carry over into Eternal War?
Can I play Techmarine in the campaign?
Is Siege or Operations the faster Armoury Data source?
Do I need to clear the campaign before touching Eternal War?
What happens if my squad wipes in Operations before extracting?
The Bottom Line
Depends on what you’re chasing. If you want Relic weapons and higher tiers, PvE is not optional – Siege’s fixed wave rewards and Operations’ Terminus kills are the only sources that exist. If you want rank, Accolades, or Eternal War’s own cosmetic track, skip the PvE grind entirely and queue straight into matches, since none of that progress crosses over anyway.
It’s a genuinely well-separated system, not a compromise – just don’t expect one grind to quietly feed the other.
