The battle for galactic control has evolved as all sides introduce deadly new ships and cunning methods of victory. Stardock has announced the Reinforcements DLC for Sins of a Solar Empire II, will launch on September 25, 2025. This content expansion introduces a brand-new command ship class—one unique vessel for each faction—and all-new Factional Victory Conditions that let players win in ways that match their empire’s lore and playstyle.

New Command Ships
Bridging the gap between capital ships and titans, command ships redefine late-game fleet compositions with devastating firepower, unique abilities, and strategic utility:
TEC Enclave – Takadaran Command Fortress
A massive support platform doubling as a mobile cruiser-scale shipyard, capable of producing TEC cruisers in the field.
TEC Primacy – Khevarkov Modular Battleship
A high-speed strike vessel with customizable hardpoints for railguns, missiles, or hangar bays.
Vasari Alliance – Sularkon Tyrant
A city-ship fortress with integrated Phase Gate, designed to lock down entire sectors.
Vasari Exodus – Anarkrul Wanderer
A colossal refugee-carrier turned warship, bristling with defenses and heavy strikecraft support.
Advent Wrath – Oblivia Dreadnought
A heavily armored frontline warship wielding a devastating Super Heavy PsiKinetic Lance.
Advent Reborn – Justicia Dreadnought
A vertical dreadnought that grows deadlier as allies fall, culminating in catastrophic retaliation.
Factional Victory Conditions
The Reinforcements DLC also introduces faction-specific win conditions, adding new strategic layers and dramatic endgame scenarios:
- Vasari – The Departure: Build massive Arkships and escape the sector through a star.
- Advent – Mass Conversion: Deploy planetary conversion structures to transform entire star systems into loyal territory in sweeping waves.
- Trader Emergency Coalition – Super Novalith Offensive: Construct an ultimate Novalith cannon capable of obliterating planets to force peace through sheer destructive power.
“The Reinforcements DLC isn’t just about adding bigger ships—it’s about giving players entirely new ways to think about victory,” said Brian Clair, Executive Producer at Stardock. “From unleashing faction-defining command ships to achieving lore-driven win conditions, every match can now end in a way that feels true to your chosen empire.”
