Space Marine 2 Class Tier List 2026: Best Builds After Patch 15.0

The best class for Ruthless and Absolute Operations in Warhammer 40,000: Space Marine 2 is Tactical, with Bulwark alongside it and Vanguard and Techmarine a step behind — and every one of the seven classes clears Absolute with the right perks and a squad that covers its gap. Checked on Patch 15.0 (1 October 2026): the patch rebuilt the Tactical perk tree, gave Tactical a melee path, and raised base damage on most primary weapons to offset a smaller Auspex Scan bonus. We keep the ranking as a provisional editorial call — it has not been re-measured in game since the patch — while the Tactical build below is rewritten for the new tree and the other builds note what the patch touched. This is a PvE Operations ranking; Eternal War is a separate balance.

The tier is an editorial judgement built from the kit and the named perks in the build section, scored on the five criteria in the methodology below. “What earns the tier” names the mechanics, not adjectives.

Conditions. A random three-player squad (one of each class, as public matchmaking enforces), classes at level 25 with the full perk tree, Relic-tier weapons, no Prestige ranks assumed; Heroic weapons noted only where they change a class’s standing. Ruthless and Absolute are scored together because the difference between them is in the numbers (enemy health, armour and health recovery rates, revive timers) rather than in what a kit can do: a class whose recovery is baked into perks keeps that advantage on both, and where a class moves between the two difficulties it is said in its build.

Five criteria, each scored 1–3. Self-sufficiency in a random squad (can it restore its own armour or health without a teammate’s help); squad value (what it gives the other two); crowd clear; elite and boss damage; margin for error (how many mistakes the kit absorbs). The scores are ours — an editorial reading of the perk texts and of how the classes play, not a measured DPS table. What is mechanic is written as mechanic with the perk named; what is judgement is written as judgement.

How to read a build. The perk tree has four columns — Core, Team, Gear, Signature — in rows of three; you run 3 core, 1 team, 3 gear and 1 signature, one per row (levels 2–4 are core row one, 5 is team row one, 6–8 gear row one, 9 signature row one, and so on to 25). Prestige perks unlock by prestiging the class after 25; how many you can run depends on the ranks you hold. Tactical perks come from the Patch 15.0 notes; the community wiki still showed the old Tactical tree on 4 October 2026, so each new perk’s level is the level of the slot the notes say it replaces. Perks of the other six classes are taken from the wiki as read on 17 September 2026; Patch 15.0 changed none of them except Techmarine’s Combat Squad Resupply. Percentages are quoted from those texts and have not been re-measured by us. Weapon variants are our picks at Relic tier.

Tactical — S-tier

Patch 15.0 gives Tactical two real builds. The starting perk now includes Kraken Penetrator rounds (bolt weapons pierce one more enemy, +20% non-headshot damage with bolters), and its old level-18 slot holds Armour Reinforcement instead.

Ranged build. Loadout: Heavy Bolt Rifle or Auto Bolt Rifle (base damage +5% and +15% in Patch 15.0) — or the Plasma Incinerator, in which case take Plasma Boost (lvl 10) instead of Relentless Pursuit (lvl 11) in the second core row — Heavy Bolt Pistol — or a second Bolt Rifle with Tactical Reserve; Chainsword or Combat Knife.

• Core (one per row): Emperor’s Judgement (lvl 4): a Finisher reloads the ranged weapon and gives the primary +20% for 10 s · Relentless Pursuit (lvl 11): +25% ranged damage for 5 s after a Gun Strike · Emperor’s Vengeance (lvl 20): a Majoris+ kill restores one magazine
• Team: Aligned Aim (lvl 13): +15% ranged damage for the squad
• Gear (one per row): Vital Data (now lvl 8): scanning an Extremis or Terminus enemy restores 50% of the Auspex charge · Marksman’s Mandate (lvl 15): marked enemies take 40% more ranged damage on top of the base mark · Mobile Auspex (lvl 22): the scan activates around you with a 30% larger radius and lasts 4 s longer (Prime Target, lvl 24, if you would rather the scan mark the most dangerous enemy for a Gun Strike)
• Signature: Tactical Reserve (lvl 9): the secondary is replaced with a Primary Bolt Rifle — two primaries, one for range and one for the swap; Marked for Death (lvl 25) instead when Majoris and Extremis elites are the threat: one of them in the scan has every Auspex damage bonus against it doubled — the notes do not extend it to Terminus-level bosses
• Prestige (if you have the ranks): Passive Chambering (replaces Exigency Charge: an unequipped ranged weapon reloads itself after 10 s — the perk Tactical Reserve was made for), Fortitude (+15% health)

Melee build (new in Patch 15.0). Loadout: Power Sword, Power Axe or One-Handed Thunder Hammer — taking one removes the primary — plus the Heavy Bolt Pistol.

• Core (one per row): Heightened Vigour (lvl 3): after a perfect parry or dodge, +10% melee and Gun Strike damage · Focused Strike (lvl 12): during a Gun Strike you keep control under heavy hits, cannot be knocked back and take 30% less damage · Armour Reinforcement (lvl 18): non-finisher Gun Strikes restore 1 armour segment
• Team: Aligned Aim (lvl 13), or Transhuman Physiology (lvl 21) when the squad is dying rather than slow
• Gear (one per row): Battle Focus (lvl 7): a perfect parry or block marks the parried enemy with Auspex · Strongpoint (lvl 16): inside the scan area you and your squad deal 20% more melee damage and take 20% less health damage · Bladesman’s Mandate (lvl 23): marked enemies take 60% more melee and 20% more Gun Strike damage
• Signature: Radiating Impact (lvl 17): a melee finisher deals area damage in 10 m · Marked for Death (lvl 25) when a Majoris or Extremis elite is the target worth doubling the scan bonuses on (not Terminus)

Why we keep it at S (provisionally): the scan no longer stacks to the old extremes — the patch notes say outright that the Auspex bonus is smaller and that primaries were buffed to even it out — but no other class picks between two complete playstyles on the same kit, and the mark still feeds the whole squad. That flexibility, not raw multiplier, is why we keep the tier until it is tested in play. The melee path is new enough that we rank the class on the ranged build; the melee build is the one to test once you know the parry timings.

Play loop (ranged): Scan the pack → Marksman’s Mandate makes the marked elites the priority → finish one target to reload and buff the primary (Emperor’s Judgement) → swap to the second Bolt Rifle instead of reloading (Tactical Reserve, Passive Chambering).

Limits and swaps: Secure Stockpile (lvl 5) now has a 90 s cooldown instead of 60 s, so it is no longer the default team pick. The melee build has no primary at all — against ranged swarms it leans on the squad.

Bulwark — S-tier

Loadout: Power Sword (Chainsword or Power Fist by preference), Plasma Pistol for charged shots at range, Combat Shield; no primary slot exists on Bulwark.

• Core (one per row): Defensive Advantage (lvl 4): a perfect parry or block creates a Shock area for 5 s, 30 s cooldown · Shock and Awe (lvl 11): enemies in a Shock area take +25% damage · Armour Reinforcement (lvl 20): non-finisher gun strikes restore 1 armour segment
• Team: Focused Restoration (lvl 5): every 30 s all squad members restore 1 armour segment, no input needed — Effective Formation (lvl 21, squad −20% health damage from Extremis/Terminus) on boss-heavy missions
• Gear (one per row): Rejuvenating Effect (lvl 8): activating the banner revives incapacitated squad members inside it · Glory’s Shield (lvl 15): −20% damage inside the banner and the banner lasts 20% longer · Invigorating Icon (lvl 23): on activation the squad regains maximum contested health (banner recharges 50% slower)
• Signature: Defensive Mastery (lvl 17): a perfect parry incapacitates a Majoris or Extremis, 90 s cooldown; Armoured Advance (lvl 25) if you get knocked around more than you parry
• Prestige (if you have the ranks): Standard Bearer (P2: invulnerable for 2 s when the banner activates), Emboldened Stand (P2: no stagger inside the banner)

Why it works: This is where the “Bulwark heals the team” claim actually lives: the banner restores armour by default (20 s, 125 s cooldown), Invigorating Icon turns the activation into a squad contested-health refill, Rejuvenating Effect makes it a revive, and Focused Restoration hands out armour passively between banners. The parry loop (Defensive Advantage → Shock and Awe) is the damage side.

Play loop: Hold the line at the objective → parry into a Shock area and hit the +25% → drop the banner when two armour bars are gone or someone is down, not on cooldown → gun-strike for armour between parries.

Limits and swaps: No primary, so ranged threats are the Plasma Pistol’s job or a teammate’s; Rapid Regeneration (lvl 14) is the alternative to Glory’s Shield when you want a 10 s burst banner. The class does not out-damage anyone — it stops the run from ending.

Vanguard — A-tier

Loadout: Melta Rifle (Instigator Bolt Carbine for a ranged-leaning game), Heavy Bolt Pistol, Combat Knife or Chainsword.

• Core (one per row): Duellist (lvl 3): perfect parry and block windows +50% · Close-Combat Focus (lvl 11): −20% ranged damage taken · Honed Reactions (lvl 20): under 50% health the perfect dodge window doubles — Conviction (lvl 19) if you prefer flat mitigation
• Team: Unmatched Zeal (lvl 13): a melee finisher on an Extremis or Terminus restores 30% health for any squad member — the named source of the class’s “healing”, and it is conditional on those finishers
• Gear (one per row): Restless Fortitude (lvl 6): after a Diving Kick, −40% ranged damage for 10 s · Shock Wave (lvl 14): the Diving Kick deals half its damage in a 5 m radius · Combat Readiness (lvl 24): Grapnel recharges 20% faster
• Signature: Tactical Prowess (lvl 9): the Grapnel can finish enemies under 33% health (not Terminus), and a Grapnel finisher fully restores its charge — the engine of the build; Adrenaline Rush (lvl 25: +5% health per Majoris+ melee kill) is the self-heal alternative
• Prestige (if you have the ranks): Launch Restoration (P2: each Grapnel use restores 1 armour segment), Fortitude (P2)

Why it works: The Grapnel Launcher is 45.45 s per charge; Tactical Prowess makes a finisher refund it, so the loop is only as fast as the finishers you can line up. Health comes back from finishers (Unmatched Zeal) and Majoris kills (Adrenaline Rush), plus the starting perk (+50% contested health from melee) — none of it is automatic, which is the reason for A rather than S.

Play loop: Melta a Majoris under a third → Grapnel finisher (charge refunded) → Diving Kick into the next pack under Restless Fortitude → repeat; save a charge for an Extremis finisher when the squad is low.

Limits and swaps: Patch 15.0 raised Melta Rifle base damage by 65% and cut its magazine from 15 to 10. Fall-off now starts closer, and by variant: Standard-Issue 2 m, Master-Crafted Alpha 2.5 m, Salvation of Bakka 3 m, Gathalamor Crusade 3 m, with the maximum reduction lowered from 50% to 30% on all four; the Salamanders Heroic version gains a fall-off it did not have, up to 70% at 25–30 m. A stronger finisher setup at point-blank range on every variant, weaker at mid range. Ranged swarms with no finisher targets stall the loop; that is when Close-Combat Focus and the Melta carry. Do not take both Adrenaline Rush and Tactical Prowess — same column, one slot.

Techmarine — A-tier

Loadout: Heavy Bolt Rifle or Plasma Incinerator, Plasma Pistol, Omnissiah Axe (class-exclusive; Power Sword and Power Axe also open).

• Core (one per row): Explosives Adept (lvl 4): +35% equipment damage · Precision Enhancement (lvl 10): the Servo-Gun locks one target and fires precision shots — 108 damage per shot on Ruthless/Absolute at 20% energy per shot, per the wiki’s table · Long-Range Barrage (lvl 20): +25% ranged damage beyond 20 m
• Team: Battlefield Repairs (lvl 13): every squad member’s Medicae Stimm fully regenerates armour and adds one extra segment — Reinforced Position (lvl 5, −25% damage and +15% damage within 15 m of an active sentry) when the map hands you Tarantulas
• Gear (one per row): Augmented Ammunition Feed (lvl 7): Servo-Gun recharges 15% faster · Fortifying Salvo (lvl 16): a Servo-Gun kill restores 1 armour segment, 30 s cooldown · Strategic Gun Strike (lvl 24): the Servo-Gun targets only Majoris+ and deals +20% beyond 20 m
• Signature: Lethal Perimeter (lvl 17): the Servo-Gun guards a zone and spends 50% less energy per shot — the hold-a-lane option; Decapitating Stratagem (lvl 9: a Majoris+ kill by the Servo-Gun refunds 100% charge, 90 s cooldown) is the elite-hunter option. Both work; pick by mission, not by dogma
• Prestige (if you have the ranks): Volatile Sentry (P1: Tarantula explosion +1000% damage, radius +20%), Defensive Stance (P2)

Why it works: The energy budget is the whole class: the default Servo-Gun spends 4% per shot, Precision 20%, Plasma 10% (wiki table). Precision mode is five shots per full charge — enough to delete a Majoris — which is why the earlier version of this guide was wrong to say the class “collapses without Lethal Perimeter”: Decapitating Stratagem pays the charge back on the kill, Augmented Ammunition Feed shortens the wait, and Lethal Perimeter is the cheaper-per-shot alternative for lanes, not a requirement.

Play loop: Activate a Tarantula if the map has one → mark the elite by looking at it and fire Precision → Majoris dies, Decapitating Stratagem refunds the charge → Omnissiah Axe the leftovers while Fortifying Salvo tops the armour.

Patch 15.0: the Techmarine can now take a Two-Handed Thunder Hammer, and Combat Squad Resupply also restores Melta Bombs.

Limits and swaps: Precision Enhancement and Plasma Enhancement are different Servo-Gun modes in different rows; running both is legal but pointless — the gun has one mode at a time. The class needs a front line; alone it is a Tactical with a slower gun.

Heavy — B-tier

Loadout: Multi-Melta (Heavy Bolter for range), Plasma Pistol; there is no melee weapon slot — the Heavy’s melee is the Stomp and gun strikes.

• Core (one per row): Thermal Boost (lvl 3): +15% ranged damage at 50% overheat or half a magazine · Multi-Kill (lvl 10): a Multi-Melta shot that kills 5+ restores 1 ammo — Fortitude (lvl 11, +30% health) with the Heavy Bolter · Auxiliary Ammunition (lvl 18): with the primary empty, 7 kills in 6 s restore 20% of the reserve, 30 s cooldown
• Team: Encompassing Aegis (lvl 5): the squad takes −25% ranged damage — Bonds of Brotherhood (lvl 21, a revive restores full health) with a squad that keeps falling
• Gear (one per row): Saving Grace (lvl 8): reviving a squad member fully restores Iron Halo and all armour · Brute Force (lvl 16): +15% ranged damage while Iron Halo is on cooldown · Emperor’s Protection (lvl 22): when the Halo spends all its energy, the squad gains 1 armour segment
• Signature: Conversion Field (lvl 25): squad members within 20 m regenerate ability charge 50% faster while the Halo is up; Coolant Reserve (lvl 17) is the solo-carry insurance when both teammates are down
• Prestige (if you have the ranks): Conviction (P1), Exponential Force (P2: melee +100% — the Stomp answer to a crowd), Auxiliary Reload (P1)

Why it works: Iron Halo blocks ranged damage and nothing else, so the class’s weakness is being touched. That is a positioning cost, not a death sentence: the Multi-Melta at point-blank range is the strongest close answer in the game, the Stomp staggers, Fortitude adds health, and Exponential Force at Prestige 2 makes the melee real. What keeps Heavy at B is that all of it costs seconds a random squad may not buy you, and the kit gives the squad shields and ammo rather than health.

Play loop: Set up behind the front line → Halo on the first ranged wave (Encompassing Aegis already halves the pain) → Multi-Melta the pack that reaches you (Multi-Kill refunds) → revive with Saving Grace to reset the Halo.

Limits and swaps: Strategic Stand (lvl 19) roots you for +15% contested health recovery — not on Absolute. Coolant Reserve is a dead perk in a full squad; take Conversion Field.

Sniper — B-tier

Loadout: Las Fusil (Bolt Sniper Rifle for headshot play), Heavy Bolt Pistol, Combat Knife.

• Core (one per row): Block Break (lvl 2): shots penetrate block stances at 50% damage — Iron Grip (lvl 4) with the bolt rifles · Vantage Point (lvl 11): +20% ranged damage after 2 s stationary · Lethal Efficiency (lvl 20): a Las Fusil shot that kills more than one enemy refunds a charge — Adaptability (lvl 19) with bolt weapons
• Team: Marksmanship (lvl 5): +10% headshot damage for the squad — Precision Targeting (lvl 13, +15% vs Extremis/Terminus for the squad) on boss missions
• Gear (one per row): Purification (lvl 6): activating the cloak clears status effects and restores all contested health · Targeted Shot (lvl 15): the first shot out of cloak deals +75% · Renewal (lvl 22): a headshot kill restores 5% cloak charge
• Signature: Emergency Override (lvl 17): at lethal damage the cloak fires for free and you are invulnerable for 5 s, 180 s cooldown — the perk that moves Sniper up on Absolute specifically; Evasion (lvl 9) when you dodge more than you die
• Prestige (if you have the ranks): Emperor’s Grace (P1: invulnerable 2 s on cloak), Versatile Precision (P1: a secondary kill restores 15% primary ammo)

Why it works: Ammo is the ceiling and the build spends every perk fighting it: Lethal Efficiency refunds Las Fusil charges on multi-kills, Renewal and Versatile Precision feed the cloak and the reserve. The cloak lasts 10 s in PvE; Targeted Shot is the payoff, Purification the self-heal. What the class does not have is anything that restores a teammate’s armour or health — Marksmanship is the whole squad contribution.

Play loop: Cloak → line up the Majoris headshot (Targeted Shot) → Las Fusil through the pack behind it (Lethal Efficiency refund) → recloak on the Renewal ticks; keep Emergency Override for the mistake.

Limits and swaps: Vantage Point wants you still, Absolute wants you moving — drop it for Dexterous Hands (lvl 12) if you run Bolt Carbines. Lethal Efficiency does nothing without the Las Fusil.

Assault — B-tier

Loadout: Thunder Hammer (Power Fist for single-target), Heavy Bolt Pistol or the one-handed Bolt Carbine; no primary slot.

• Core (one per row): Winged Fury (lvl 2): melee out of a sprint or dash deals +100% and hits a 7 m area, 5 s cooldown · Knowledge of the Enemy (lvl 12): +15% melee vs Majoris and Extremis · Armour Reinforcement (lvl 18): non-finisher gun strikes restore 1 armour segment — the only armour-recovery perk in the tree
• Team: Squad Cohesion (lvl 5): squad abilities recharge 15% faster — Strategic Strikes (lvl 13, squad +20% melee vs Extremis/Terminus) on boss missions
• Gear (one per row): Wings of Flame (lvl 7): the Jump Pack dash damages along its path and always counts as a perfect dodge · Strong Strikes (lvl 14): a dash hit restores 1 Jump Pack charge, 10 s cooldown · Zealous Blow (lvl 23): a Ground Pound kill restores 10% Jump Pack charge
• Signature: Commitment (lvl 25): a perfect dodge with the Jump Pack dash restores its charge; Ample Ammunition (lvl 9) reloads and gives +50% ranged for 10 s per Jump Pack use if the pistol is doing real work
• Prestige (if you have the ranks): Unyielding Oath (P1: invulnerable 3 s while charging a Ground Pound), Hammer of Wrath (P2: −30% ranged damage and no stagger for 15 s after a Jump Pack use)

Why it works: The Jump Pack is 40.65 s per charge, and the whole build is about not waiting for it: Strong Strikes, Zealous Blow and Commitment each hand charge back. On sustain the honest statement is short: the tree has no heal-on-kill — the earlier version of this guide claimed one and it does not exist — only Armour Reinforcement on gun strikes, Perseverance’s damage reduction during charged attacks (lvl 4) and contested health. That, plus no primary, is why Assault sits at B on both difficulties.

Play loop: Dash into the pack (Wings of Flame perfect dodge, Winged Fury AoE) → Ground Pound the survivors (Zealous Blow refund) → gun-strike a stagger for armour → dash out before the second wave.

Limits and swaps: Precision Strike (lvl 22) halves the Ground Pound radius for double damage — a boss perk, not a horde perk. Ascension (lvl 17) is the alternative signature for takeoff damage; Commitment keeps the loop moving.

A tier list tells you which class is worth the hours; it does not shorten them. Every class has its own unlock curve, and the order you push them in changes how long the whole set takes — our class levelling guide lays out the fastest route to maxing each one, and the Prestige guide covers what the Prestige perks above cost to reach.

The weapons named in each build are our picks for that class at Relic tier; how individual weapons rank by role against swarms, elites and Terminus-class threats is covered in the Space Marine 2 weapon tier list.

Public Operations matchmaking fields one of each class per squad — the developers said in September 2024 that they did not intend to change that for regular matchmaking (PCGamesN, reporting the developer response). Every combination below is therefore three different classes; whether a private-lobby setting relaxes the rule is outside this ranking.

Tactical + Bulwark + Vanguard

The safest random trio. Auspex marks give the Vanguard finisher targets under 33% faster (Tactical Prowess), Unmatched Zeal heals the squad on the finishers, and the Bulwark’s banner covers the moments the loop stalls.

Techmarine + Vanguard + Bulwark

Zone, execute, hold. Precision Servo-Gun softens the Majoris, the Vanguard grapples the finisher, Battlefield Repairs plus Focused Restoration keep armour flowing without anyone spending a stimm early.

Heavy + Sniper + Bulwark

Two backline classes need the one front-line class that does not need them: the Bulwark holds aggro, Encompassing Aegis and Marksmanship stack on the squad, and the Sniper’s Emergency Override is the insurance a backline pair otherwise lacks.

Patch 15.0 (1 October 2026) is the balance point this ranking is checked against. For PvE classes it changed:

• Tactical: eleven perks replaced or moved (Signal Jammer → Tactical Reserve, Steady Aim → Focused Strike, Precise Calibration → Bladesman’s Mandate, Expert Timing → Strongpoint, Concentrated Fire → Prime Target, and more), Marked for Death reworked, Kraken Penetrator rounds moved into the starting perk, Secure Stockpile 60 → 90 s, and a melee path with Power Sword, Power Axe or One-Handed Thunder Hammer in place of the primary. Every slot change is in our Tactical rework breakdown.
• Weapons: base damage up on Bolt Rifle (+10%), Auto Bolt Rifle (+15%), Heavy Bolt Rifle (+5%), Bolt Carbines (+7.5–15%), Plasma Incinerator (+10% on the common shot), Heavy Bolter (+5%), Pyreblaster and Pyrecannon (+10%); Melta Rifle +65% and Heavy Melta Rifle +60% with smaller magazines and shorter range.
• Techmarine: Two-Handed Thunder Hammer added; Combat Squad Resupply covers Melta Bombs.
• Endgame: Crucible Mode opens for any class at level 25.

No other class’s perks changed, which is why their builds stand. Saber says Patch 16 will revisit Siege Blessings and Atonements; nothing class-related is announced for it yet.

Reading a conditional perk as a passive one

Unmatched Zeal heals on Extremis and Terminus finishers, not on kills; Emperor’s Vengeance needs a Majoris kill; Strong Strikes needs a dash hit. Builds that count on the effect without the condition run dry on Absolute, where the conditions come less often.

Perks that need a state you rarely hold

Perks tied to full armour, a full magazine or standing still (Thermal Boost’s magazine half, Vantage Point, Strategic Stand) are not bad — they are situational. Take them when the build creates the state (Thermal Boost with a weapon that lives at 50% heat) and skip them when it does not.

Two abilities of the same kind in one squad

Not two classes — matchmaking prevents that — but two recovery tools timed together: a Bulwark banner and a Techmarine Battlefield Repairs stimm in the same second waste one of them. Call the banner; hold the stimm.

Levelling the wrong weapon

The build above names the weapon; mastery on a different one does not transfer. Bulwark and Assault players in particular level a primary they cannot equip because the menu shows one.
