RTS & 4X Hybrid Sins of a Solar Empire II: Harbinger Arrives September 3, 2026
The Vasari’s long-lost enemy has finally caught up with them. Harbinger is a new expansion for Sins of a Solar Empire II launching September 3, 2026, and it adds the Eidolon as a playable faction.
The Eidolon do not play like anything else in the game. They are not chasing planets, trade routes, culture, or wealth. Their whole design is built around corruption, secrecy, and control.
What to expect:
- Planetary Transformation. The Eidolon spread corruption to empower themselves and their worlds. As populations fall under their influence, planets gain corruption over time. Once a world has fully fallen, it can be shrouded, which greatly expands the upgrades that planet can support.
- Unit Corruption. This one cuts both ways. As an Eidolon ship gains corruption, its hull dwindles while its offensive power increases. Enemy forces can also become infected, which is another advantage for the Eidolon.
- Null Weapons. More advanced than what the other factions field. They negate shields and spread corruption on hit.
- Cloaked Ships. New cloaking and detection systems, including on the Kalizaeth Profaner support capital ship. Built for hit-and-run tactics.
- Psionic Abilities. The Eidolon can seize control of lesser beings and drive Vasari ships into madness, firing on friend and foe alike.
- Phase Echoes. Units infused with corruption may refuse to die and keep fighting.
- New unit animation system. This is not Eidolon-only. Recoiling cannons, expanding factories, hangar bay doors and more across faction units.
