About the Mission
Every year, millions of tonnes of plastic enter our oceans, threatening sea turtles, fish, seabirds and countless other marine species.
Ocean Guardian turns an endless-runner adventure into an awareness experience: every pollution encounter becomes a learning moment, not just an obstacle.
Play, learn, and carry a little more ocean-awareness with you after every swim.
