Cleaning an entire Moon sounds like a ridiculous job for one person, which is probably why Moon Sweepers lets you bring a whole crew along for the ride. Friends can work on different parts of the lunar surface, operate their own vehicles, and contribute to the same cleaning operation. Multiplayer also changes how certain upgrades and equipment purchases work, so there are a few things worth knowing before everyone starts spending money. Here's how co-op works, what to expect from crossplay, and how to get the most out of playing together.

Does Moon Sweepers Have Multiplayer? How Many Players Can Join?
Yes, Moon Sweepers supports online cooperative multiplayer for up to 16 players in the same cleaning operation.
That means you can play with just one friend, organize a smaller group, or bring together a full crew of 16 players to tackle the lunar surface.
Everyone works toward cleaning the Moon, with players able to collect dust, explore, use equipment, and contribute to the operation's progress.
There's no requirement to fill an entire lobby, either. Two people can work together perfectly well, and larger groups simply provide more opportunities to divide the workload.
Moon Sweepers also supports solo play, so you don't need friends online to begin cleaning, earning money, or expanding your operation.
Does Moon Sweepers Have Crossplay?
Moon Sweepers launched on October 23, 2026, for Windows PC through Steam. Online co-op is available for players on that platform.
However, crossplay between PC and consoles has not been confirmed. There's no established PlayStation or Xbox multiplayer compatibility to rely on.
If you're planning to play with friends, the supported option is to have everyone playing the PC version through Steam.
Crossplay and ordinary online multiplayer aren't the same thing. A game can support several players online without allowing someone on PC to join a friend using an entirely different platform.
For Moon Sweepers, you should plan around Steam multiplayer rather than assuming cross-platform connections are available.
How to Play Moon Sweepers With Friends
Playing together requires an online multiplayer session that your friends can join. One person starts or opens a multiplayer-accessible game, while the other players connect to that session.
Before organizing a larger group, I'd recommend starting with one friend and making sure both players can enter the same world successfully.
- Make sure everyone has Moon Sweepers installed through Steam.
- Check that each player is running the same updated version of the game.
- Have one player host or open a multiplayer-accessible session.
- Use the available multiplayer joining options to connect the other players to that session.
- Confirm everyone has entered the game before heading out to different cleaning areas.
- Decide where the group will work and begin your shared cleanup operation.
One useful detail is that simply opening a multiplayer lobby isn't the same as actually playing co-op. Another player needs to join the session.
This also matters for the Steam achievement OH You Have Friends?, which requires starting a multiplayer game with at least one other player.
Can You Play Moon Sweepers With Just Two Players?
Absolutely. Two-player co-op is supported, and you don't need a large team to benefit from working together.
In fact, I think two players have one of the easiest arrangements to manage. One person can focus on collecting dust while the other takes care of nearby unfinished sectors, deliveries, or construction.
There's no need to assign formal jobs or stick together for the entire session. You can clean the same area or work separately, depending on what you're trying to accomplish.
Are Upgrades Shared in Moon Sweepers Multiplayer?
Some upgrades are shared across the crew, while others belong to individual players.
Patch 1.0.3 introduced an important change to the Upgrade Matrix. Everyone in a multiplayer session now uses the host's Upgrade Matrix, and upgrades purchased there by any crewmate apply to the whole crew.
That means players can contribute to improvements without needing every person to purchase the same Matrix upgrade separately.
For example, the crew can benefit from shared bonuses such as Market Contracts, which increases dust-selling payouts, or cleaning improvements purchased through the Matrix.
However, purchasing a personal cleaning tool or vehicle doesn't automatically provide identical equipment to everyone else.
Here's how the distinction works:
| Purchase Type | How It Works in Co-op |
|---|---|
| Upgrade Matrix | Shared through the host's Matrix across the crew |
| Handheld Tools | Players purchase their own equipment |
| Individual Tool Improvements | Personal equipment upgrades aren't automatically shared |
| Vehicles | Each player purchases and owns their vehicles |
For anyone returning after playing the launch version, this distinction is particularly useful. The shared Matrix behavior changed after release, so older upgrade arrangements don't necessarily reflect how co-op works now.
Our Moon Sweepers All Upgrades Guide covers the available Matrix bonuses, handheld improvements, and equipment upgrades.
How Do Vehicles and Equipment Work in Multiplayer?
Vehicles are especially useful when several players want to clean different parts of the Moon at once.
However, having someone in your crew purchase a large sweeper doesn't mean everyone automatically owns one.
Players buy their own vehicles and can manage those vehicles through Garages.
Patch 1.0.3 also improved vehicle management by allowing owned vehicles to be stored, retrieved, and upgraded through any Garage rather than requiring the original one.
That makes it more convenient to manage equipment as your operation spreads away from the starting area.
There's also the Crew Transport Van, which costs $2,000 and serves a transportation role rather than functioning as another dust-cleaning vehicle.
I'd avoid having everyone immediately spend money on identical equipment. A player who enjoys cleaning with handheld tools might prefer improving their broom, while someone covering large distances can focus on vehicles.
You can still contribute to the same operation without purchasing the same upgrades.
Best Way to Play Co-op in Moon Sweepers
One of the biggest advantages of multiplayer is that nobody has to handle every task alone.
Collecting dust, transporting materials, maintaining the selling system, and finishing partly cleaned areas can all compete for your attention in solo play.
With friends, those jobs can happen at the same time.
For Two Players: Split Collection and Deliveries
With two people, I'd start by having one player focus on cleaning while the other keeps an eye on collected materials and nearby unfinished sectors.
You can switch responsibilities whenever you want, but this avoids both players constantly returning to the station at the same time.
Once you have more advanced equipment, one person can operate a sweeper while the other works on construction or automation.
For Three or Four Players: Give Everyone a Useful Job
With a slightly larger group, a practical arrangement is to separate cleaning, transportation, and infrastructure.
- Cleaning: Work through untouched sectors using handheld equipment or vehicles.
- Deliveries: Keep collected materials moving toward the station rather than letting them accumulate.
- Construction: Improve conveyor connections, automated collection, and processing equipment.
- Exploration: Find unfinished regions, untangle flags, and complete survey sites while checking where the crew should clean next.
These aren't character classes or assigned in-game roles. They're simply useful ways to divide responsibilities while everyone contributes to the same operation.
If your crew is building an automated selling system, our Moon Sweepers Auto Selling Guide explains how to connect collectors and conveyors to the station intake.
For Larger Groups: Spread Out Without Losing Track of Progress
With eight, twelve, or even sixteen players, it's easy for everyone to end up cleaning whatever patch of dust happens to be closest.
That works, but I'd organize the crew into smaller groups covering different areas instead of sending everyone to the same sector.
The Moon Map can help with this. Orange sectors are untouched, blue sectors are partially cleaned, and green sectors are complete.
Have groups finish partially cleaned areas when convenient, then move into fresh territory rather than repeatedly overlapping each other's work.
Keeping a few people near your transport and processing infrastructure can also help ensure the collected dust actually reaches the selling system.
Sixteen people collecting dust won't necessarily translate into sixteen times the income if the entire delivery system is backed up.
Moon Sweepers Multiplayer Not Working? What to Check
If you or your friends are having problems with multiplayer, start with the installed game versions.
Everyone should be running a compatible version before attempting to join the same session. Moon Sweepers received several multiplayer-related fixes shortly after launch, including changes to shared upgrades and construction.
Friend's Splitters or Mergers Aren't Working
Patch 1.0.3 fixed problems with Splitters and Mergers built by players other than the host.
If a teammate's conveyor connections aren't behaving properly, check that everyone has updated the game before dismantling the entire system.
Upgrades Aren't Shared as Expected
Make sure you're distinguishing Upgrade Matrix purchases from personal equipment.
The host's Upgrade Matrix applies across the crew, while individual tools and vehicles still have their own purchases and ownership.
If one player buys a new broom and another player doesn't receive it, that's different from a shared Matrix upgrade failing to apply.
Can You Play Split-Screen or Local Co-op?
Moon Sweepers' established multiplayer mode is online co-op through Steam. A separate local split-screen mode hasn't been confirmed, so players looking to share one screen shouldn't assume it's available.
For the supported multiplayer experience, plan on separate PCs running the Steam version.
Moon Sweepers is perfectly playable solo, but co-op gives you more freedom to tackle the Moon in different ways. Whether you're cleaning with one friend or coordinating a full sixteen-player crew, the biggest advantage comes from working together without everyone needing to do the same job. Take advantage of shared Matrix upgrades, equip players for the work they enjoy, and keep your collection and selling systems organized as the operation grows.
