Class leveling in Warhammer 40,000: Space Marine 2 is the grind of taking each of the game’s classes from level 1 to their level cap by earning XP in Operations, Eternal War, and Siege Mode. The fastest route isn’t about picking one magic Operation or farming spot — it comes down to matching your difficulty setting to how consistently you actually clear it, then sequencing which class you level first so every class after it goes faster. This guide covers that order, the honest difficulty threshold where higher settings start paying off, and where Prestige fits into the decision.
TL;DR
- Speed comes from difficulty plus consistent clears together — not from which Operation or mode you pick
- Level one class to the cap first before spreading XP thin across all six
- Higher difficulty settings pay out more XP per clear, but only if your squad isn’t wiping and restarting
- Prestige resets that class’s level and perks for a permanent XP bonus — decide before you buy every perk, not after
- Exact XP-per-clear numbers shift between patches, so treat any figure here as directional, not a fixed target
What Is Class Leveling in Warhammer 40,000: Space Marine 2?
Each of the game’s classes levels independently, with its own XP bar, its own skill tree of Class perks bought with Requisition Points, and its own cap. Each class has 25 levels, and leveling up grants access to new perks in the skill tree. Once a class hits that cap, the only way to keep progressing it is the Prestige system, which resets it in exchange for a permanent bonus. Patch 14 (the Confrontation Update, released July 28) also added a seventh playable class, Techmarine, though its leveling curve isn’t documented well enough yet to include here with confidence — this guide focuses on the six classes players have been leveling since launch.
| Class | Playstyle | Leveling Difficulty | Best For |
|---|---|---|---|
| Tactical | Versatile ranged support, scanning utility | Forgiving, low mistake cost | Learning enemy patterns safely |
| Bulwark | Shield tank, close-range control | Forgiving, absorbs damage | Stabilizing squads on new maps |
| Heavy | Heavy weapons, suppression | Slower pace, survivable | Farming higher difficulties safely |
| Assault | Melee, jump pack aggression | Punishing on higher difficulty | Players who already know the maps |
| Vanguard | Grapnel mobility, burst damage | Punishing if overextending | Confident co-op players |
| Sniper | Long-range precision, support | Requires squad backup | Rounding out a leveled roster |
Where to Get XP Fast for Class Leveling
Operations is still the main leveling engine — co-op PvE missions that hand out XP, Requisition Points, and a chance at Armoury Data on every clear, scaled by the difficulty you pick. Operations can vary in difficulty and there are 6 difficulty options: Minimal, Average, Substantial, Ruthless, Lethal, and Absolute, and completing an operation earns the player Experience Points, Requisition Points, and possibly Armoury Data. Eternal War (the PvP mode) and Siege Mode also feed class XP, and Patch 14 leaned into making both more approachable — Eternal War’s gear grind was flattened so all weapons and equipment are available from Level 1, and Siege got adjusted resource rewards on top of it. If you’re weighing PvP as a leveling shortcut, the same patch brought extensive balance tweaks to Assault, Vanguard, and Bulwark in PvP, and Siege Mode was also adjusted with new resource rewards and increased enemy resistance caps at higher waves, which is worth knowing before you commit a session there.
| Source | What You Get | Requirement | Who It Suits |
|---|---|---|---|
| Operations (co-op PvE) | Class XP, Requisition, Armoury Data | None — scales with difficulty | Anyone leveling a class from scratch |
| Eternal War (PvP) | Class XP, weekly rewards | All gear unlocked from level 1 as of Patch 14 | Players who prefer PvP pacing |
| Siege Mode | Class XP, resource rewards | Squad coordination for later waves | Groups running long sessions together |
Best Class Leveling Methods
| Method | Speed | Effort | Best For |
|---|---|---|---|
| Operations at a difficulty you clear consistently | Fast, reliable | Low to moderate | Most players, most of the time |
| Operations pushed one difficulty above your comfort zone | Higher per-clear XP, inconsistent | High | Squads that rarely wipe already |
| Siege Mode long sessions | Steady, session-length dependent | Moderate | Coordinated squads with time to spare |
| Eternal War (PvP) | Variable, match-dependent | Low gear barrier now | Players who enjoy PvP over grinding PvE |
Best Class to Level First (and When to Switch)
The first class you fully level shapes how fast every class after it goes, because it’s what teaches you enemy attack patterns, Operation layouts, and gives you the Armoury Data and Requisition stockpile the rest of the roster draws from. Starting with a forgiving class means fewer wipes while you’re still learning, which is the actual lever on leveling speed — not which specific class you pick.
| Class | Levels Faster Via | What It Unlocks | When to Level It |
|---|---|---|---|
| Tactical | Consistent ranged damage, scan utility keeping squads alive | Marksman and utility perks | First — safest way to learn the game |
| Bulwark | Absorbing hits while you read enemy telegraphs | Shield-focused perks | First or second, alongside Tactical |
| Heavy | Slower but forgiving suppression play | Heavy weapon perks | Once you have Artificer-tier gear from earlier clears |
| Assault / Vanguard | Aggressive melee or mobility play that punishes mistakes | Jump pack / grapnel perks | After you already know the maps |
| Sniper | Precision damage that needs squad support | Long-range perks | Once one or two other classes are online |
Difficulty vs Speed: The Honest Threshold
Higher difficulty settings pay out more XP and better Armoury Data per clear, but the cost of a failed run scales with it too — wasted time, no reward, and a squad that has to restart cold. The honest threshold for moving up is when you can clear the current difficulty without a wipe most of the time, not when you feel like you’ve “done enough” of it. There’s no hard level gate on the higher tiers, but Lethal is tuned for level 25 classes with Artificer or Relic-tier weapons — you can attempt it earlier, but enemy health scaling and reduced survivability will make clears inconsistent. Our Lethal and Absolute difficulty guide breaks down exactly what changes at those tiers if you want the full picture before committing a squad to it.
Tip
Before pushing a full squad up a difficulty tier, run one Operation there solo or duo first. If you’re getting downed repeatedly or burning through Medicae stims, drop back down — the XP gap isn’t worth a string of failed runs.
Prestige and Rewards: What Leveling Actually Unlocks
Leveling a class rewards Class perks along the way, cosmetics tied to specific difficulty clears, and eventually the option to Prestige. Prestige unlocks at Class level 25 and is activated from the Armouring Hall for a Requisition Points cost — it resets that Class’s level to 1 and wipes its purchased Class perks, which you then rebuy. In exchange, each Prestige rank grants an additional permanent 10% XP boost with the Class you hit prestige with, stacking by 10% for every prestige on that Class, up to a maximum of four ranks per class. Weapon levels sit on a separate track and aren’t affected — one player who’s fully prestiged every class confirmed you also don’t have to re-level your weapons when you reset a Class.
Warning
Prestige resets Class perks you already bought, not just your level — decide whether you want it before you spend Requisition on every perk in the tree. We cover the full mechanics, including what carries over and what doesn’t, in our Prestige guide, so this article won’t repeat it.
| Reward | How You Get It | Why It Matters |
|---|---|---|
| Class perks | Level 1 to 25, bought with Requisition Points | Defines your build's core loadout |
| Prestige perk slot | Reach level 25, reset via Armouring Hall | Permanent perk plus stacking XP bonus |
| Difficulty-tied cosmetics | Clearing specific Operations at set difficulties, or completing Ordeals | Signals which content you've actually cleared |
| Weapon mastery | Separate XP track plus Armoury Data | Unaffected by Class Prestige resets |
Weekly Leveling Plan: Step-by-Step Walkthrough
Follow this sequence to get it done fast.
-
1
Pick one anchor class and commit for the week
Tactical or Bulwark, since both stay survivable while you learn Operation layouts.
-
2
Run Operations at a difficulty you clear without wiping
consistency beats a higher difficulty setting you can't sustain.
-
3
Bank a small stockpile of Requisition and Armoury Data
don't spend everything on perks the moment you unlock them, in case you decide to Prestige soon after hitting 25.
-
4
Decide on Prestige before your anchor class hits the cap
check the Prestige guide's full breakdown so the reset doesn't surprise you.
-
5
Start your second class using gear and map knowledge from
a Heavy or Assault run goes faster once you already know where enemies spawn.
Common Misconceptions About Fastest Leveling
Higher Difficulty Always Means Faster Leveling
Not if it costs you the clear. Due to armor changes on higher difficulty tiers, pushing ahead of your squad — the preferred playstyle for classes like Assault and Vanguard — is heavily punished, and a wipe pays zero XP. A slower, reliable clear at a lower tier consistently beats a fast one at a tier you can’t sustain.
You Need Every Class Maxed Before Trying Harder Content
You need one competent class, not six. Lethal and Absolute are tuned around gear tier and build quality on a single class, not your account-wide roster — level one class properly first and the rest follow faster once you know the fights.
Prestige Is Something You Do Right After Hitting 25
It’s optional, and resetting immediately after you’ve spent Requisition on every perk in the tree is the expensive version of it. Read what actually carries over before you touch the reset button, not after.
Our Take: Is Chasing Max Difficulty Worth It Before You've Leveled?
Our Take
No — not until your clears are consistent, and that matters more than which class you start with.
The instinct to jump straight to Ruthless or Lethal for the bigger XP number is understandable, but a failed run pays nothing while a clean clear on an easier tier pays something every time. Leveling one class properly first, then letting that experience carry into the next five, is the actual fast route — not a specific farming spot or difficulty setting. Exact XP-per-clear figures have moved with past balance patches and will likely keep moving, so treat any number you see quoted, including here, as a rough guide rather than a fixed target.
