Evolve, Engineer, Contain
$0.99 · Designed for iPad. Not verified for macOS.
Petriarch is a premium microbial ecology strategy game where every solution can evolve into a new problem.
GROW A LIVING COLONY
- Complete sixty handcrafted ecology trials driven by diffusion, metabolism, pH, oxygen, waste, mutation, cooperation, and competition
- Place strains into gradients and guide the colony toward stable targets without wait timers
NEW: MICROBE FOUNDRY
- Engineer strains for eight missions: oil cleanup, medicine production, plastic breakdown, soil restoration, oxygen generation, survival beneath ice, containment, and living circuits
- Tune movement, metabolism, reproduction, temperature tolerance, light sensitivity, consumption, and containment
- Release cells into a deterministic 24 by 18 culture and watch generations mutate, spread, compete, cooperate, and sometimes escape the intended role
- Balance objective progress, diversity, contamination, nutrients, and ecological stability
- Replay Daily Strain and Weekly Colony scenarios with optional Game Center scores
A COMPLETE OFFLINE LAB
- One purchase with no ads, subscription, in-app purchase, login, tracking, analytics, or developer-operated server
- Sixty trials, all foundry missions, fieldbook, local records, audio cues, and twelve-movement score work offline
- Dynamic Type, VoiceOver, reduced motion, and non-color strain symbols are supported
Petriarch is an original fictional simulation, not laboratory or environmental guidance.
