About game
Navigate your microscopic creature through a dangerous petri dish environment while growing from a simple cell into a massive organism. You consume green food particles to increase your mass and climb the local food chain. Survival depends on avoiding aggressive red predators that hunt you down until your size advantage shifts the balance. Bacteria forces you to make tactical choices by selecting mutations that alter your speed, defensive traits, or growth rate at every stage of development. Boss encounters test your reflexes and require careful maneuvering to overcome apex threats. You collect DNA throughout each run to purchase permanent upgrades that give you a head start next time. Daily challenges keep your skills sharp as you chase high scores on the leaderboard. Play Bacteria for free directly in your web browser without downloading any files.
