At A Glance
Moon Sweepers multiplayer for Clean the Moon is online co-op up to 16 on Windows Steam. Patch 1.0.3 shares cash and Upgrade Matrix rows. Launch-week reviews had shared money with personal upgrades — that is the old rule. DragDrop Games, app 5335510. Steam.
There is no cross-play flag. Console friends cannot sit in the lobby. Host Friends-only or the equivalent Steam overlay, then assign sweeper / hauler / builder so nobody double-places a depot.

How do I host a 16-player Moon Sweepers lobby?
Everyone buys Moon Sweepers on Windows Steam. Clean the Moon has no console invite, no Roblox server browser, and no cross-save. The host starts a session; recaps show a Friends only toggle on a fresh Moon. If a friend cannot see the lobby, they are on the wrong app or the wrong OS — platforms. Moon Sweepers multiplayer is Steam-to-Steam only.
- Do01Host on Windows Steam, app 5335510
- Do02Confirm patch 1.0.3 or newer so upgrades share
- Do03Name one treasurer before anyone opens the supply wall
- Do04Place the first dump together — it will not move
- Do05Assign hexes or pile one crater; both work
- Do06Recall only your own vehicles from the garage
- Do07Keep discord.gg/5ATRkXkAAe for callouts — channel names TBA
Camera sickness
Some players report motion issues. That is a personal settings problem, not a reason to boot them. Let them lower motion or walk while others drive. Store lists full controller support if a teammate hates mouse look.
What did patch 1.0.3 change for shared upgrades?
Launch week: money pooled, broom purchases did not. 1.0.3 made Upgrade Matrix rows server-wide. Recaps on the matrix say broom, cleaning, suit, logistics, and Economy apply to whoever is playing. That is why duplicate Wide Broom buys are now a tax, not a flex.
How should we split sweeper, hauler, and builder?
The Moon has enough dust for everyone to sweep. Roles exist to stop three people placing three depots in three wrong craters. Use this table as the executable split for Moon Sweepers multiplayer.
| Lobby size | Sweepers | Hauler / emptier | Builder |
|---|---|---|---|
| Solo | You | You | You — delay belts |
| 2 | Both on one hex | Whoever is full walks | One hammer after first broom |
| 4 | 3 on adjacent hexes | 1 on dump / chute | 1 places packager line |
| 8 | 6 split two fronts | 1 garage / belts | 1 matrix spender + pads |
| 16 | Two stations (e.g. North + East) | 2 on chutes | 2 on belts / catchers — never 16 depots |
Pile or split
Official copy says the surface is large enough either way. Piling one crater is easier voice. Splitting stations is faster Moon-clean. Teleport between visited stations exists; recaps priced it — still Unverified. Do not teleport-bankrupt the shared wallet.
One treasurer
Open Tab, call the cash, click once. Economy and container upgrades help everyone. Personal jetpacks come from leftover, not from the first $100. Spend order: how to make money.
Then automate the walk tax

Which upgrades are personal vs server-wide?
If the click lives on the supply wall next to tools, assume personal. If it lives on the Upgrade Matrix tabs, assume shared. Garage vehicle upgrades sit on the vehicle you own — teammates do not inherit your hopper.
| System | Shared? | Co-op rule |
|---|---|---|
| Cash | Yes | One spender |
| Household / Wide broom unlocks | Matrix / wall mix — treat broom rows as shared after 1.0.3 | Buy once |
| Cleaning width (tools, not vehicles) | Yes (matrix) | Buy once |
| Economy / logistics / suit matrix | Yes | Economy early |
| Tool belt, jetpack, lamp, NV, boots | No | Each player who needs night |
| Vehicle hopper / motor / suction | Per vehicle | Upgrade the rover people actually drive |
| Garage recall | Your vehicles only | Do not yoink a teammate’s hopper |
| Buildings | World objects | Cannot move; place as a group |
What breaks a Clean the Moon co-op session?
Wrong platform, old patch, duplicate spends, and unmovable buildings. Also: belts that swallow (patch if you are pre-1.0.3), J.O.O.N.A.S. without catchers, and a treasurer who buys ramps for trickshots before a broom.
| Failure | Fix |
|---|---|
| Friend on PS5 | They cannot join |
| Pre-1.0.3 lobby | Update — upgrades were personal |
| Three depots in three craters | Stop placing; refunds 1.0.4 — confirm UI |
| Everyone buys NV | Fine (personal). Everyone buys Economy — waste |
| Dust vanishes on belts | Update; watch one cycle before expanding |
| J.O.O.N.A.S. idle | Need capsule catchers; 1.0.4 rework |
| AFK in a 16-stack | Do not keep buying vehicles for ghosts |
Voice without fake channels
Use the official invite. Channel names on this wiki stay TBA. Do not invent #looking-for-group. Discord.
Do I need a full 16?
No. Solo is listed. Extra bodies help only if they sweep, empty, or build. A 16-player Clean the Moon lobby with fourteen tourists is a shared wallet with two workers. Start 2–4, add fronts when walking is the tax, then automate — automation.
What next
Next: once walking is the tax, automate haul on automation.
FAQ
Do upgrades share?
Yes on the Upgrade Matrix since patch 1.0.3. Jetpack / lamp / NV / boots stay personal.
Is there cross-play?
No flag on the store page we checked. Console friends cannot join.
Can we move a badly placed depot?
Buildings do not move. Check 1.0.4 refund UI before you delete a dump you still need.
