The Season 09 Expansion Pass includes: 

• BioGenesis Expansion (May 5, 2025): Take command of the forces of life itself in 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? 
• Shadows of the Shroud Expansion (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.
• Infernals Species Pack (Q4 2025): Forge your destiny in the 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?
• Stargazer Species Portrait (available now): Dream of the stars with this exclusive portrait, available immediately upon purchasing the Season 09 Expansion Pass. Featuring three phenotypes and unique animations, the Stargazer Species Portrait is perfect for players who seek to embody the spirit of cosmic curiosity.

Players can also look forward to a free new update launching alongside the BioGenesis expansion on May 5. The Stellaris 4.0 “Phoenix” update will bring major changes and improvements to the gameplay experience, including new Population Groups and Workforce, a rework of the Trade system, selectable precursors, and much more.
