MYCELIUM turns uncertainty into readable strategy. Frontier cells show forecasts, attacks expose their real odds, and hostile colonies telegraph source, direction and target before they grow. Close same-family square perimeters to capture and reinforce their interiors, trigger chain reactions, explore seeded worlds and challenge another player through direct P2P — all in the browser, free and without an account.
