Macrobio.io | Evolve or Die

You start as one fragile cell under the microscope. Swallow everything smaller, outrun everything bigger, and grow into the monster that owns the petri dish. Macrobio is a fast arcade eater: one run takes a couple of minutes, one mistake takes everything. 🦠 EAT OR BE EATEN Drag to steer. Double-tap to dash. Split to snatch prey that thinks it is safe. Mass is your health, your size and your score at the same time — every bite makes you stronger and slower, and every rival is watching for the moment you get greedy. 🧬 10 EVOLUTION PATHS Pick a path at the start of a run, then stack mutations on top of it. No two runs play the same: • Macrophage — tanky and efficient, rots slower • Warden — spiked armor, attackers burst on contact • Parasite — siphons mass out of smaller cells without touching them • Phototroph — grows in the light and seeds its own food • Plague — leaves a poison trail behind you • Discharge — electric shock pulse • Swarm — a swarm of killer drones • Cyst — cloak, vanish, ambush • Magnet — drags food and prey toward you • Cryo — chills every cell that comes close 🎨 35 STRAINS TO COLLECT Open lootboxes for new strains, from common cells to legendary ones, and repaint anything you own in the Chroma Lab. 🧪 BOOSTS AND THE INCUBATOR Brew potions for extra XP, growth, harvest or a bigger starting mass. Your incubator keeps working while the game is closed and grows boost hours for you — come back, claim them, and go on a rampage. 🏆 SOMETHING TO CHASE EVERY DAY Daily rewards, streaks, missions, a season pass and prestige — there is always one more level, one more strain, one more record to beat. 📴 PLAY ANYWHERE Every rival cell is driven by AI, so the arena is always full and the game runs fully offline. No Wi-Fi, no waiting for a match, no lag — open it in a queue, on a plane, anywhere. Free to play. Optional purchases and ads support development. Grow. Devour. Evolve. How big can one cell get?
