Germline

From cell to organism

Germline is a PC organism-building game where you start with a single heart and grow a biological experiment from one cell to adulthood. Pulse the heart to generate energy, then place and connect organs to shape production. Hearts make energy, brains unlock automation, and spore-producing organs supply clones for expansion.

Build and automate

You can pulse the heart yourself, or develop systems that buy, research and expand automatically. Play actively, leave the laboratory running, or combine the two; offline progress lets it keep growing while you’re away. Organ placement and connections affect how your production works, while research adds mutations whose effects can be combined into synergies.
