BIOME — Watch Life Unfold in Real Time
Biome is a living ecosystem simulator powered by autonomous agent behaviour. Every creature thinks — it hunts, flees, starves, and breeds through emergent Lotka-Volterra dynamics, right on your screen.
--- WHAT MAKES BIOME DIFFERENT ---
Real emergent behaviour, not scripted loops — each agent uses sight radius, hunger, and steering rules to make decisions 60 times per second.
Population graph — watch Lotka-Volterra oscillations form live as prey boom and bust under predator pressure.
Tap any agent — inspect its hunger, age, kill count, species stats, and current behaviour state in a detailed sheet.
Seed sharing — copy a seed code and send your exact ecosystem to a friend so they can replay the same collapse.
--- 5 HAND-CRAFTED BIOMES ---
SAVANNA — Lions, wolves, deer, and eagles in the amber grasslands. Classic predator-prey oscillation.
ARCTIC — Polar bears stalk seals beneath the ice. Sparse resources mean brutal die-offs. [Pro]
DEEP SEA — Sharks pursue fish and seals in total darkness. A razor-thin two-species equilibrium. [Pro]
JUNGLE — Maximum species density. Jaguars, bears, eagles, and chickens — chaos guaranteed. [Pro]
CUSTOM — Mix any species, blend terrains with the slider, and build your own extinction event. [Pro]
--- 20 SPECIES, 5 ROLES ---
Producers (Grass) → Prey (Rabbit, Deer, Zebra, Fish, Seal, Chicken) → Predators (Fox, Wolf, Jaguar) → Apex (Eagle, Bear, Polar Bear, Shark, Lion) → Omnivores (Human). Plus two absurd Pro species: T-Rex and Dragon.
--- TRIGGER ECOSYSTEM EVENTS [Pro] ---
Drought — food supply halved, prey hunger spikes immediately.
Disease — a 40% mortality spike hits one prey species.
Meteor — wipes a random zone off the canvas instantly.
Invasion — four non-native apex predators appear from nowhere.
Population Bomb — one prey species doubles in an instant.
