The orbit is drowning in trash, and you are part of the last janitor fleet that can still save it. Pilot your cleaning ship through eight dangerous orbits, collect space debris, and clear the way for the future. Between asteroids, active satellites, mines, and cosmic storms, every maneuver counts. Your mission: • Clear diverse orbits across the solar system • Collect debris and remove dangerous space junk • Dodge asteroids, satellites, mines, and cosmic hazards • Use your shield, magnet, boost, and laser at the right moment • Expand your fleet with extraordinary cleaning ships • Earn your flight license and prove your skills • Unlock achievements and compete via Game Center • Discover in the CC Academy why space debris is a real threat MORE THAN JUST A SPACE GAME A single tiny piece of debris can destroy a satellite and create more dangerous fragments. This can trigger a chain reaction that threatens satellites, communications, and future space missions. Cosmo Cleaner combines accessible arcade gameplay with a mission inspired by a real challenge facing our future. Not every hero wears a spacesuit. Often, they are the quiet heroes of everyday life: janitors who show up day after day and keep everything running. In Cosmo Cleaner, they become the saviors of orbit. Your shift begins. Clean the orbit. Protect the future.
