Moon Sweepers Patch 1.0.4 Arrives as Surprise Co-Op Hit Keeps Climbing Steam Charts

Moon Sweepers just got its most substantial update yet. Developer DragDrop Games released Patch 1.0.4 on October 25, 2026, bringing major improvements to the game’s automated cleaning robot, new suit gear, a reworked Moon map, and a long list of multiplayer and performance fixes, just two days after the quirky co-op cleaning game launched on Steam.

The $7.64 title has quickly become one of October’s bigger indie surprises, pulling in over 50,000 concurrent players and a “Mostly Positive” rating from more than 1,300 Steam reviews since its October 23 release.

What Patch 1.0.4 Actually Fixes

The update’s biggest focus is J.O.O.N.A.S., the game’s automated cleaning robot companion. DragDrop Games reworked its pathing so it no longer makes unnecessary trips back to the dock, cutting down on wasted idle time significantly. Performance also got a real boost: the studio reports frame rates up to 20% higher on large bases, smoother driving and faster teleports between stations, and ground geometry hidden behind the Moon’s horizon no longer rendering unnecessarily.

Beyond performance, the patch adds new suit gear, an improved Moon map, much faster saving on big bases, and automatic save backups, alongside a broad pass of multiplayer and bug fixes. As a two-person team, DragDrop Games acknowledged in its patch notes that it can’t fix everything overnight, but said it’s “listening, working, and not slowing down” in response to community feedback since launch.

What Moon Sweepers Actually Is

Moon Sweepers drops players on a lunar surface buried under a thick layer of dust, starting with nothing but a single toothbrush. The core loop involves collecting lunar dust, hauling it to a depot, and launching shipments to earn money, which then funds upgraded cleaning tools, more carrying capacity, and eventually full cleaning vehicles.

Online co-op lobbies support up to 16 players, letting friends split up to cover more ground or tackle the same area together, though the game’s own marketing leans into the joke that whether everyone actually pitches in is “another matter.” Later progression opens up automation options, including robot vacuums and packagers, alongside production chains for Moon Sand and the considerably more valuable Moonstone, which sells for roughly seven times what raw Moon Dust fetches.

The game is currently available at a 15% introductory discount, priced at $7.64 down from $8.99, through October 30. It’s Windows-only via Steam, with no PS5, Xbox, or Switch version announced.
