Microcosm: Idle Cell Empire

Life starts with a single cell. Where it goes is up to you.

Microcosm is a relaxing idle evolution game about growing one microscopic cell into an entire living organism. Culture organelles, synthesize resources, draft mutations, and watch your colony evolve — even while you're away.

🔬 A LIVING WORLD UNDER THE MICROSCOPE
Every cell is its own tiny factory. Organelles orbit the nucleus, gathering ATP, amino acids, enzymes, and more. Merge them into higher-tier structures and expand from a humble lipid droplet all the way to a complex organism, across 50 cells to unlock.

🧬 DRAFT MUTATIONS — NO TWO RUNS ARE THE SAME
Every cell division offers a choice of three permanent mutations. Build a glass-cannon metabolism, an unkillable immune fortress, or a wide, efficient colony. Exclusive mutation pairs create real branch points, so every lineage evolves differently.

🦠 DEFEND AGAINST INFECTION
Pathogens multiply constantly. Assign leukocytes to fight them off — but every cell defending is a cell not gathering. Repel outbreaks for big rewards, and decide for yourself where the line sits between growth and defense.

⚡ MASTER YOUR METABOLISM
Organelles cost energy to run. Overload your metabolic budget and production throttles — so specialization beats brute force. Integrate a permanent symbiont into each cell to shape how it grows.

♾️ EVOLVE FOREVER
Divide, speciate, and emerge through stacked prestige layers, each one compounding your power. There's always a deeper strategy and a bigger organism to build.
