For players deciding the best class for Siege in Space Marine 2, Tactical is the safest all-round pick for public squads. Auspex Scan gives all three players one target to erase before the defensive line breaks.
À retenir
- Siege is a three-player PvE mode on Kadaku with waves, side objectives, requisition terminals, reinforcements, and extraction.
- Tactical is the recommended general class because Auspex Scan gives the whole squad a shared damage window.
- Patch 13.0 added Siege 2.0 systems including new purchases, bosses, objectives, Blessings, and Atonements.
- Hotfix 13.2 disables Atonements on Normal difficulty and caps enemy resistance.
Siege is a three-player PvE mode set on Kadaku. Each run combines escalating waves, side objectives, requisition terminals, reinforcements, and extraction. Tactical is the most flexible starting choice. Bulwark is stronger when melee pressure keeps dropping the team, while Heavy needs a protected firing lane.

Best class for Siege in Space Marine 2 : the quick answer
Pick Tactical when you need a reliable class without knowing your teammates. Mark a Terminus enemy, an Extremis threat, or the Majoris pack blocking a revive. Wait until allies can shoot or use their abilities, then call the Scan and focus fire.
Do not use Scan the instant it recharges. Holding it through a quiet wave is often the correct choice. A well-timed Scan on a boss or a dangerous pack is worth far more than a personal damage spike.
Key takeaways
- Tactical is the best general choice because Auspex Scan creates a shared damage window.
- Choose Bulwark when the squad needs a close-range anchor and safer revives.
- Choose Heavy only when teammates can keep enemies out of its firing lane.
- Use requisition to solve the next threat, not simply because a terminal is available.
- Move sectors together and extract when the next sequence cannot be funded safely.
Best class for Siege Space Marine 2 build : Tactical
Use a weapon you can control consistently. Then favour perks that improve Scan uptime, team damage against marked targets, or reinforcement control where your available perk tree supports it. Read the in-game perk text before committing points, because Saber can adjust class interactions in patches.
| Element | Priority | Action |
|---|---|---|
| Ability | Auspex Scan | Save it for bosses, Extremis enemies, or a Majoris pack stopping the squad. |
| Primary weapon | Reliable control | Choose dependable weak-point fire over changing weapons after every wave. |
| Perks | Scan value and charge economy | Avoid bonuses that require you to be isolated or far from the objective. |
| Equipment | Emergency response | Keep it for a revive, sector entry, or pressured side objective. |
Stand far enough back to read the fight, but not so far that Bulwark is left alone in melee. When the horde closes in, retreat towards the defended axis. Chasing a single duel can turn a clean hold into three separate fights.
Priority order during a Siege run
- Before the wave: take position near the next defence axis and keep the squad together.
- At the first dangerous pack: remove enemies that stop movement or threaten a downed ally.
- When a boss appears: call the Scan, choose an accessible weak point, and avoid three isolated duels.
- At the terminal: buy only what fixes the next concrete problem, such as ammunition, a charge, or survival.
- At a sector change: leave together. Extraction is a valid reward outcome, not a failed run.
Hotfix 13.2 caps enemy resistance for regular and Terminus enemies. Late waves still punish wasteful spending and scattered fire. The change rewards grouped damage and abilities used while the whole squad can benefit.

When Bulwark, Heavy, or another class is better
Bulwark is the strongest alternative when players keep falling at close range. Its shield and banner have their greatest value where both allies can use them. Do not push far ahead of the squad.
Heavy is excellent on a stable lane. It loses value when enemies constantly reach its position or when it must perform repeated revives. Let Bulwark or Vanguard create space before committing firepower.
Vanguard suits players who can enter and leave a pack without consuming all squad support. Sniper shines when priority targets remain visible. Assault rewards movement mastery, but it is not the easiest first class for learning Siege pacing and economy.

Mistakes that end strong Siege runs
- Copying a class without its rôle: Heavy needs protection, while Bulwark needs allies close enough to benefit.
- Using Scan every wave: spend it only when the marked threat can die immediately.
- Buying by habit: check ammunition, charges, and squad health before spending requisition.
- Playing Siege like a normal Operation: resources must survive the next wave and the next sector.
- Ignoring difficulty rules: Atonements are disabled on Normal difficulty under hotfix 13.2, but other difficulties can differ.
Keep the same loadout for two comparable runs before judging it. Identify the wave where control or ammunition fails. Then change one thing only, such as Scan timing or a terminal purchase. That exposes the real problem instead of hiding it behind several changes.
