About Stellaris: Season 09

About this DLC

Unlock the future of your empire with every Stellaris release for 2025!

The Stellaris: Season 09 Expansion Pass is your gateway to an entire year of cosmic evolution, psionic mysteries, and apocalyptic infernos. With instant access to the exclusive Stargazer Species Portrait, this expansion pass delivers three major content packs that will redefine the Biological and Psionic Ascensions and the most ambitious species pack so far!

Purchasing the Expansion Pass grants access to all four DLCs as soon as they become available.

Included in this Expansion Pass:

Stargazer Species Portrait (Day 1 Unlock)

Dream of the stars with this exclusive portrait, available immediately upon purchasing Stellaris: Season 09. Featuring three phenotypes and unique animations, the Stargazer Species Portrait is perfect for players who seek to embody the spirit of cosmic curiosity.

This exclusive portrait comes with Season 09 for Stellaris, allowing you to dream big about the stars as you explore the galaxy. Like every Stellaris Species Portrait, it comes with three variants (phenotypes) and custom animations. Players can select this portrait in the empire creation skin before starting a new game session.

BioGenesis (Releases Q2 2025)

Take command of the forces of life itself in Stellaris: BioGenesis. Engineer living ships, terraform entire ecosystems, and wield advanced genetic tools to shape the destiny of your empire. Will you create a utopia of adaptation and growth or weaponize biology to dominate the stars?

  • Overhauled Genetic Ascension: Choose from three distinct paths—Cloning, Purity, and Mutation—and customize your evolution.

  • Player Crisis Path: Unleash the unstoppable Behemoth Fury on the galaxy.
  • Three New Origins: Play as evolutionary predators, a sapient planetary ecosystem, or a fortress civilization.
  • New Megastructure: Construct the Deep Space Citadel to control hyperlane choke points.

Shadows of the Shroud (Releases Q3 2025)

The psionic plane holds untold power—but at what cost? Shadows of the Shroud is a complete overhaul of the Psionic Ascension path, introducing new moral dilemmas, patron allegiances, and the ever-present temptation of ultimate destruction.

  • Breach into the Shroud: Shape your empire’s spiritual destiny with a revamped Shroud system.
  • Shroud Panel: Track your empire’s attunement and unlock new powers.
  • Revamped End of the Cycle: The ultimate deal with the devil—can you delay the inevitable?
  • Psionic Auras: Let your Shroud influence shape entire star systems.
  • New Content: Origins, civics, ships, government types, and more!

Infernals Species Pack (Releases Q4 2025)

Forge your destiny in the Stellaris: Infernals Species Pack. Adapted to relentless heat and volatile landscapes, you wield the power of extreme environments to reshape the galaxy. Will your empire thrive in the heat, or be consumed by the very forces it seeks to command?

  • Player Crisis Path: Burn the galaxy to ashes as your empire thrives in destruction.
  • New Origins: Rise from planetary infernos or face an expanding red giant in a fight for survival.
  • Volcanic Worlds: A new planetary class with unique districts, events, and archaeological sites.
  • New Species & Customization: Ships, portraits, civics, and more!
