Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Germline combines incremental progression, organism building and expanding layers of simulation. We want to learn how players approach these systems, which builds they enjoy, and where progression becomes confusing or repetitive. Early Access gives players an opportunity to help shape the game’s balance, usability and depth while development continues.”

Approximately how long will this game be in Early Access?

“We currently estimate that Germline will remain in Early Access for approximately 18–24 months.

This is an estimated timeframe rather than a fixed release date. Development progress, player feedback, testing, and the scope of future updates may influence when the game is ready for full release.

Our priority is to deliver a polished, stable, and enjoyable experience rather than rush towards a specific deadline.”

How is the full version planned to differ from the Early Access version?

“We plan to expand the variety of mutations, challenges, world traits and narrative discoveries, creating more ways to build organisms and approach each reality. We also aim to refine long-term progression, improve onboarding and accessibility, and strengthen the single-player experience through balance changes and player feedback. These plans may change as we learn from testing and community feedback.”

What is the current state of the Early Access version?

“The Early Access version focuses on single-player progression: pulse a heart to generate energy, build and connect organs, discover mutations, unlock automation, explore the Network and create universes. Players can reset realities, carry permanent upgrades into new runs, and progress toward ecosystems and multiverses.

It also includes species growth, rare morphs, crossbreeding, habitats, challenge realities, offline progress, multiple save slots, achievements and cosmetic customization. Multiplayer, co-op, PvP, leaderboards and public profiles are not available in this version. Balance, interface clarity and later progression are still being refined.”

Will the game be priced differently during and after Early Access?

“We currently plan to keep Germline at a lower price during Early Access to reflect its ongoing development and reward early supporters.

We are leaning towards maintaining a consistent price throughout Early Access, with a potential increase when the game reaches its full release to reflect the additional content, features, and improvements.

Any planned pricing changes will be communicated to the community in advance.”

How are you planning on involving the Community in your development process?

“We plan to gather feedback through Steam discussions and share changes through development announcements. Bug reports, suggestions and accounts of player experiences will help us prioritize improvements to progression, build variety and interface clarity.

We encourage players to share their strategies, unusual organisms, and the moments where the game feels rewarding, confusing or frustrating.”

About This Game

From one cell to living worlds

Germline is a single-player idle growth game that begins with one founder cell. Raise and collect 60 species, from bees and sunflowers to wolves, tigers and octopuses. Watch each organism grow through four life stages: Founder, Developed, Juvenile and Adult.

Build a living machine

Pulse the heart for energy, place organs and connect them to shape your production. Research mutations, discover synergies and develop automation as your organism grows. Combine active play with idle and offline progress, then return to choose your next upgrade.

Find your next favourite

Choose from five starter species and unlock more by raising new species to adulthood. Reproduce for a chance to discover new colour forms, and crossbreed unlocked species for another chance at rare morphs. Develop a habitat with multiple residents and keep track of the specimens and discoveries you want to remember.

Expand beyond one organism

Send clones across the Network, capture nodes and create universes. Grow civilisations, explore their stories and choose how your worlds develop. When you are ready, reset reality and carry permanent upgrades into a new beginning. Later progression opens challenges, ecosystems and multiverses.

Your journey

  • 60 species to unlock and raise through four life stages.

  • Private statistics and a Discovery Archive for your collection.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some of the content in Germline was created with the help of generative AI tools. This includes the in-game music soundtrack and some store and marketing artwork. All AI-assisted content was reviewed and selected by a developer. The creatures you see in the game are not made by AI. They are built by the game’s own procedural generation system from each organism’s genome
