Moon Sweepers, a co-op toothbrush epic, sells over 600,000 copies

Picture a spotlight on a very small broom. Moon Sweepers, a co-op game from DragDrop Games on Steam, hands you and your crew a job: clear the Moon of Lunar Dust, armed with a toothbrush. I could not look away from that premise.

The facts: the game has sold more than 600,000 copies in its first few days, and its concurrent player count was at 80,385 and climbing as the source was written.¹ Genre is cooperative cleanup with base building. The sources give no price and no release date.

What sets it apart is the ladder. Budget constraints leave your crew with a toothbrush, and the more dust you gather, the more funds you earn to move up to a bigger broom, then larger and more flexible brushes, and eventually a sweeper truck.¹ Later you can place solar panels, buildings and conveyor belts, so the chore grows into a flourishing empire.¹ The source likens it to Powerwash Sim or Viscera Cleanup Detail in space, with a touch of Astroneer.¹

The studio says it has been fixing bugs and improving the game since launch, and that something bigger is coming: update 1.1, due in December, aims “to bring a lot more depth to the game.”¹ The late game is the focus, with new production machines and chains, extra materials and products that need more complex production lines, more tools and upgrades, more automation at larger scale, more building options, expanded progression, and performance work for bigger bases.¹

There is also the matter of what happens once the whole Moon is clean. The studio’s answer is “more work,” and it teases plans for what follows without saying what they are.¹ The developer also says it is reading player feedback daily to decide what to fix next.¹

Our read: A game about scrubbing dust drew a crowd this large, and the studio is already pointing to the late game as its weak spot. December’s 1.1 update is the one to watch: it will show whether the added depth keeps players building once the toothbrush is a distant memory.
