Warhammer 40,000: Dawn of War - Soulstorm: Complete Guide

A guide to Dawn of War – Soulstorm (March 2008), the third and final expansion to Relic's original Dawn of War, developed by Iron Lore Entertainment: the resource system, all nine factions, openings, the Kaurava conquest campaign, multiplayer and the mods that keep it alive.

Researched September 2026 — current as of the final official patch of the classic release, plus the August 2025 Definitive Edition (see below). Live games change; check the linked sources if something differs.

Version note: The standalone Soulstorm store page is now unlisted on Steam at the publisher's request (existing owners keep it; the page can only be reached by direct link). On 14 August 2025 Relic released Warhammer 40,000: Dawn of War – Definitive Edition, which bundles the base game, Winter Assault, Dark Crusade and Soulstorm with all nine factions, four campaigns, 100+ multiplayer maps, 64-bit support, 4x-resolution textures, better pathfinding, a 4K/widescreen-friendly camera and an integrated mod manager. Owners of the classic Anniversary Edition get a 30% upgrade discount. Everything below applies to Soulstorm's content in either version; if you are buying today, the Definitive Edition is the version to get.

Quick Start

  1. It's standalone. Soulstorm runs on its own and includes all nine armies for skirmish and multiplayer. The campaign uses the Dark Crusade-style conquest meta-map, expanded to a whole star system.
  2. Capture points fast. Requisition comes from Strategic Points, Relics and Critical Locations on the map. Your builders and first squads should grab them immediately.
  3. Build Listening Posts on captured points. They defend the point and upgrading them increases income.
  4. Build power generators. Power is the second resource; generators on Slag Deposits give extra power.
  5. Reinforce squads instead of rebuilding. Adding models to an existing squad is cheaper and faster than a new squad.
  6. Morale matters. Squads with broken morale fight poorly. Use leaders, commanders and upgrades to keep morale up and use suppression and heavy weapons to break the enemy's.
  7. Melee vs ranged. Pick fights your units are good at. Tie up enemy shooters in melee; keep your shooters away from assault troops.
  8. Tech through your HQ and key buildings. Each faction has tiers unlocked by upgrading its HQ and building tech structures.
  9. Soulstorm adds flyers. Every army gains an air unit. Bring anti-air in the late game.

Resources

Resource Source Notes
Requisition Strategic Points, Relics, Critical Locations Main resource; income scales with points held and Listening Post upgrades
Power Generators (bonus on Slag Deposits) Needed for tech, vehicles and heavy units
Faction-specific See faction table Some armies track population or special meters differently

Economy rules of thumb

The Nine Factions

Faction Style Beginner notes
Space Marines Elite, flexible infantry and vehicles Great first faction; forgiving and versatile
Chaos Aggressive infantry, daemons and dark psychic powers Strong melee and debuffs
Orks Numbers, melee and a unique population system tied to Waaagh! banners Snowbally; swarm and overwhelm
Eldar Fast, fragile, advanced tech and teleports High skill cap
Imperial Guard Massed infantry, strong artillery and tanks Good for defensive, gunline play
Tau Empire Superior ranged firepower, weak melee, Kroot auxiliaries Keep enemies at range
Necrons Slow, durable, power-based economy (they don't use requisition like others) Unique; hard to kill, strong late
Sisters of Battle (new) Faith-powered, ranged elite infantry, zealots and the Penitent Engine Faith fuels special abilities
Dark Eldar (new) Fast raiders, melee, stuns and poisons Hit-and-run; harvest souls for powers

Soulstorm's new armies

Openings

Each faction differs, but a typical opening looks like this:

  1. HQ builds builders (servitors, slaves, grots and so on, depending on faction) — usually two or three early.
  2. Builders make the first production building and a generator.
  3. First infantry squads capture strategic points immediately.
  4. Listening Posts on captured points.
  5. Second production building or tech building once income stabilizes.
  6. Commander or hero for early fights (for most factions).
  7. First HQ tier-up once you control your share of the map.

Combat Mechanics

The Soulstorm Campaign

The campaign is a turn-based, Risk-style meta-map conquest of the Kaurava system: 31 territories spread over four planets and three moons (the store page counts 34 maps in total across the expansion). You choose one of the nine factions and fight the others for control.

How it works

Campaign tips

Multiplayer and Community

Mod What it does
Unification Adds many more Warhammer 40,000 factions to Soulstorm
Ultimate Apocalypse Large-scale overhaul with titans and huge battles
Soulstorm Bugfix Mod Community fix pack (2013) for bugs left after official patch support ended
Skirmish AI mods Community AI replacements that make skirmish opponents much tougher

On the classic 32-bit release, big mods often need a large-address-aware (4GB) patch to avoid memory crashes; each mod's install instructions cover this. The Definitive Edition is 64-bit and has an integrated mod manager, but classic mods are not guaranteed to work on it unchanged — check each mod's page for which version it supports. Always back up the game folder before installing mods.

FAQ

Do I need the original Dawn of War to play Soulstorm? No. Soulstorm is standalone.

How many factions are there? Nine: Space Marines, Chaos, Orks, Eldar, Imperial Guard, Tau Empire, Necrons, Sisters of Battle and Dark Eldar.

Is Soulstorm's campaign better than Dark Crusade's? Many players prefer Dark Crusade's campaign; Soulstorm's is bigger (a whole star system) and includes all nine factions.

Can I still play multiplayer? Yes, but the population is small and depends on community hubs. Skirmish vs AI and mods are the main way people play.

What's the best mod? Unification for more factions; Ultimate Apocalypse for massive battles; a community skirmish AI mod for tougher AI.

Should I buy Soulstorm or the Definitive Edition? The Definitive Edition (August 2025). The standalone Soulstorm page is unlisted on Steam, and the Definitive Edition includes Soulstorm plus the base game, Winter Assault and Dark Crusade with modern-PC improvements.

Is Soulstorm the last Dawn of War 1 expansion? Yes, it was the third and final expansion. Dawn of War II (2009) and Dawn of War III (2017) followed.
