Four moves behind every payout
Steam describes a simple economy: clean the ground, move the dust, get paid, then buy equipment that reduces the next trip.
- 01
Sweep
Clear lunar dust with your starting tool.
- 02
Collect
Fill your storage and carry the dust.
- 03
Ship
Deliver to a depot and launch the shipment for payment.
- 04
Upgrade
Spend earnings on tools, capacity, depots and later vehicles.
The beginner guide combines the official game loop with reported controls and prices. Check the current game build before relying on untested figures.
Begin with a short route near the station and watch what happens to a single load. If the dust gauge fills before you finish cleaning, compare the brush and capacity options. If the walk takes longer than the sweeping, see how a Packager and conveyor route can shorten the return trip.
Once deliveries are working, expand one step at a time. A vehicle and unloading route can help with wider ground, while an automatic collection line needs a working connection from its collector to the intake. Test a small load first and check your balance before adding branches or processing machines.
For a shared session, agree on the next purchase and check the co-op version and upgrade rules. If a capsule stops or a friend cannot join, use the troubleshooting checklist to identify the first point of failure. The map and exploration section can help the crew choose its next work area and plan the trip back.
Version-aware advice
What changed after launch
The game changed quickly in its first days. Check the version before following a guide written for the launch build.
Patch 1.0.3 · 24 October 2026
Crew-wide upgrades
The crew uses the host's upgrade matrix, and a purchase upgrades everyone. This supersedes launch-day advice about individual upgrades.
Plan one crew-wide upgrade path; the host's matrix applies to everyone from 1.0.3 onward.
Recheck guides written before 1.0.4. The robot now works away from players and sends capsules toward a catcher. Follow the Joonas setup and troubleshooting steps.
A save created in 1.0.4 cannot be opened in an older version. Preserve your save before changing builds.
Solo or with a crew
Plan the work, then share the upgrades
Moon Sweepers supports single-player and online crews of up to 16. Patch 1.0.3 made upgrade-matrix purchases crew-wide. If friends cannot join, start by checking that everyone is on the same game version.

Before you buy
Check the official PC requirements
The Steam listing is the source of truth for supported platforms and current requirements.
Minimum listed: Windows 10, Intel i5-8400 or Ryzen 5 2600, 8 GB RAM, GTX 1650 or RX 570, DirectX 11 and 2 GB storage.
Recommended listed: Windows 11, Intel i5-10400 or Ryzen 5 3600, 16 GB RAM, GTX 1660 Super or RX 5600 XT, DirectX 12 and 4 GB storage.
Steam lists Windows and online co-op; check its current listing for pricing, controller support and platform availability. The 1.0.4 Proton startup fix is not a Steam Deck Verified rating. If your system meets the requirements but the game fails to start, use the startup and save troubleshooting steps and check the latest developer announcements.
Platform availability
Is Moon Sweepers on Nintendo Switch?
Checked 27 October 2026. We confirmed the Windows Steam release but found no official Nintendo Switch or Switch 2 release announcement.
Windows PCThe game is available through Steam. Check the PC requirements before buying.
Nintendo Switch / Switch 2No official release announcement found in this check. There is no confirmed Nintendo launch date to quote; this does not rule out a future port.
Steam DeckA separate PC handheld, not a Nintendo platform. Patch 1.0.4 addresses older Proton startup issues; that fix is not a Verified rating or a performance guarantee.
A Steam key does not unlock a Nintendo copy. Check the platform named on the product before paying, and use the official Steam listing and developer announcements for changes.
Buying and activation
Moon Sweepers Steam Key and Activation
A Steam key is a product activation code. It is different from an in-game keyboard binding, a Steam Wallet code or an account offered for sale.
Buy directly on SteamPurchase for your own account, then install from your Library. You do not need to find a separate retail key.
Redeem a product keyCheck that the listing names Moon Sweepers by DragDrop Games, Steam activation and your region. This guide does not verify third-party sellers, stock or lowest-price claims.
Send a Steam giftChoose the gift option at checkout if available. The recipient accepts the gift on their account; gifting restrictions can differ by region. See Steam's gift help.
Activate a key and check your Library
- Sign in to the Steam account that should own the game.
- Open the Games menu and choose Activate a Product on Steam. Follow the prompts and enter the product key.
- Check the activation result and confirm that Moon Sweepers appears in your Library. Install it from there.
If activation fails, record the exact error and check the product and region on your order. An invalid or already-used key needs follow-up with the seller; do not post the full code publicly. A successful activation followed by a launch error is a different problem: use the startup troubleshooting checklist.
