How to get Warhammer 40,000: Dawn of War – Soulstorm running today

Apply the Large Address Aware flag to Soulstorm.exe so it can use 4 GB of memory, as described in this Steam guide; players report it stops the crash after stronghold missions.
If the game still crashes after a stronghold, lower the graphics settings before the final fight and reload, the workaround players still use (Steam Community).
For further stability, PCGamingWiki lists the Soulstorm Overdrive Performance Patch, which changes how the game allocates memory.

Synopsis

The third and final standalone expansion for the real-time strategy game Dawn of War, adding the Dark Eldar and Sisters of Battle for nine playable armies. Players gather resources by holding map points, build squads and fight battles centered on close combat. Its campaign is a turn-based map spread across several planets and moons, broken up by real-time battles and stronghold assaults.

Developer: Relic Entertainment
Released: 2008
Best version: Soulstorm is no longer sold on its own on Steam; it comes only in the Dawn of War Anniversary Edition (Classic), which bundles it with the original game and the other expansions and unlocks every race for online play.
Genre: Strategy

Reception

Critics were mixed at release, with a PC Metascore of 73 from 37 reviews, praising the size of the roster but faulting the campaign, balance and new air units. Steam players rate it Overwhelmingly Positive today, though much of that praise goes to the series as a whole and to large fan mods such as Unification and Ultimate Apocalypse. Recent negative reviews call the planetary campaign a step down from Dark Crusade, with repetitive defensive battles. Crashes after stronghold missions remain a common complaint.

3/5

Controls feel natural on a modern controller or mouse and keyboard
Standard real-time strategy mouse and keyboard controls with box selection, hotkeys and squad orders. There is no controller support. Source: pcgamingwiki.com.
Menus, text or interface are hard to read on today's screens
Widescreen cuts off the top and bottom of the view and stretches the interface, which only a fan mod corrects. Source: pcgamingwiki.com.
Saving is fair: free saves or frequent checkpoints, little lost progress
Saves work as usual in this RTS, but the known crash after winning a campaign stronghold means players reload a save from before the final fight, often with lower graphics settings, so saving before each stronghold matters. Source: steamcommunity.com, pcgamingwiki.com.
It teaches itself: no guide needed to make progress
A tutorial can still be replayed at any time from a button at the bottom of the skirmish menu, even after skipping it at first launch. Source: steamcommunity.com.
Pacing drags: grind, filler or forced backtracking
The planetary campaign sends players through the same stronghold and territory battles on every run, which recent players call stale, though defensive battles can be settled by an automatic dice roll instead of being played. Source: steamcommunity.com.
Camera or movement fights the player
The camera sits very close to the ground by default and cannot zoom out far, so players turn to camera mods to see the battlefield. Source: pcgamingwiki.com, steamcommunity.com.
