Moon Sweepers on Steam

Moon Sweepers is sold on Steam for Windows PC, and Steam is the only storefront confirmed for the game. It launched on October 23, 2026 from DragDrop Games, with a US list price of $8.99 and a launch discount to $7.64 that the store says ends on October 30. You need 64-bit Windows 10 or newer and a broadband connection, and the current public build is version 1.0.3.

The main limits to know before buying: Steam Deck compatibility is listed as Unknown, there is no macOS or Linux version, and the game is still in an active patching phase after a rough launch. The sections below cover what you pay, what your PC needs, how to install and keep your saves safe, and which Steam features are actually listed.

Moon Sweepers Steam Store Facts at a Glance

These details come from the official Steam listing and Steam's own configuration data, as captured on October 25, 2026. Prices and review scores change quickly, so treat them as a snapshot.

Price, Launch Discount and the Brick by Brick Bundle

On the US store, Moon Sweepers costs $8.99. During the introductory offer it drops 15% to $7.64, and the store states the offer ends on October 30. No statement has been made about what happens to the price after that date, so do not assume the discount will return soon.

Regional prices follow Steam's own pricing. During the launch window, the discounted price was £6.79 on the UK store and 7,64€ on the euro store. Your local price may differ, so check the purchase box while signed in to your own account.

The store also offers a bundle called Brick by Brick x Moon Sweepers. It pairs Moon Sweepers with another tidy-up game, Brick by Brick: Tidy Up the Small Town!, and gives an extra 10% off each item. During the launch sale that stacked to 26% off, taking the pair from $15.28 to $11.33 on the US store.

The bundle only saves money if you actually want the second game. If you only care about cleaning the Moon, the single purchase is cheaper.

System Requirements for Moon Sweepers on Steam

The store lists two hardware tiers. Both require a 64-bit processor and operating system, and both list a broadband internet connection.

Some early previews copied the minimum memory and storage figures into the recommended column. The official store lists 16 GB of RAM and 4 GB of storage for the recommended tier, so use those numbers.

The requirements do not name a resolution, graphics preset or frame-rate target. Meeting the minimum tier is not a promise of smooth performance, especially on a large, heavily built base or in a busy co-op lobby.

Download Size Versus Storage Requirement

Steam's depot data shows a download of roughly 448 MiB and about 1.03 GiB on disk for the current build. That is well under the 2 GB minimum, but keep the listed space free anyway. Patches arrive often at this stage, and save files grow as your base expands.

Steam Deck, macOS and Linux

Steam Deck compatibility is listed as Unknown. That is neither a Verified badge nor a confirmation that the game fails on the device. If handheld play is your main reason to buy, wait for Valve's rating or reliable player reports.

The store lists Windows only. There is no native macOS or Linux build.

Install and Launch Moon Sweepers Through Steam

Installation follows the normal Steam process, but a few checks save trouble later, especially if you plan to join friends.

1. Buy the game from the official Moon Sweepers store page, or redeem a valid Steam code if you received one.
2. Install it from your Steam library. The install folder is named Moon Sweepers, and the game runs from MoonSweepers.exe.
3. Let Steam finish any pending update before the first launch, so you start on the current public build.
4. On the first launch, pick up the free starting toothbrush and read the Field Manual. On keyboard it opens with H; on a controller it sits in the pause menu.
5. Before inviting friends, confirm everyone has updated. The 1.0.3 patch notes state that all crewmates must be on version 1.0.3 to play together.

Signing the employment form starts your shift in a new world.

Version 1.0.3 and Steam Beta Branches

The game moved quickly from its launch build through version 1.0.1 to the public 1.0.3 patch on October 24, 2026. Steam's branch list also showed a separate preview branch labelled 1.0.4 on October 25.

Stay on the default public branch unless your whole crew agrees to switch together. A player on a preview branch can end up on a different version from the host, and the developer has made version matching a requirement for co-op.

Patch 1.0.3 changed several things that affect how you play on Steam:

• Upgrades are shared: the whole crew uses the host's upgrade matrix, and anyone's purchase upgrades everyone.
• The host can kick or ban players from the Your Crew list in the ESC menu.
• Heavily cleaned bases that failed to load now load again, and saves check and repair themselves.
• Machines can stand across several foundations, and demolishing a garage no longer deletes the vehicles kept there.
• The developer reported up to about 20% higher frame rates on big bases in its own tests.

One issue remains open: J.O.O.N.A.S units stopping when players move away is still listed by the developer as a priority fix, not a solved one.

Steam Features: Co-op, Controllers, Languages and Achievements

The Steam listing confirms single-player and online co-op lobbies for up to 16 players in total. It also lists in-game chat and online interactivity. There is no local split-screen and no cross-platform play flag, which makes sense because the game exists only on Windows through Steam.

Each person in a co-op lobby needs their own copy of the game on their own Steam account. The 16-player figure is a lobby limit, not the number of people one purchase covers.

Controller Support

Steam lists Full Controller Support, and the game ships with a Steam Input configuration. You can play with a gamepad, but expect some friction in building mode and vehicles. Players have complained about the vehicle camera recentering itself, and some found building rotation awkward to find on a pad.

Languages and Translation

The interface supports 19 languages, including English, French, German, Spanish, Japanese, Korean, Polish, Portuguese, Russian, Simplified and Traditional Chinese, Danish, Finnish, Norwegian, Swedish, Turkish and Italian. Only English has full audio and subtitles. The developer's AI disclosure says generative AI helped translate in-game text into the supported languages, so expect occasional awkward wording outside English.

Steam Achievements

There are 33 Steam achievements. They include milestones for dust collected, money earned and spent, deposits, and Moon completion at 1%, 10%, 50% and 100%. The higher completion steps are a long-term goal: the Moon has well over 160,000 sectors, and solo players with every upgrade have reported reaching well under 1%.

Saves, Steam Cloud and Backups on Steam

Steam's cloud configuration for Moon Sweepers points to this local save folder:

%USERPROFILE%/AppData/LocalLow/DragDropGames/MoonSweepers/MoonSessions

That folder is where your worlds live. Because it is set up for Steam Cloud, your saves can follow your account between Windows PCs, but only after Steam finishes syncing.

Version 1.0.3 added save protection. A damaged save is repaired automatically on load from its backup or a recent snapshot, and every save is checked before it replaces the previous one. You get a message if anything had to be repaired.

A manual backup is still worth a minute of your time:

1. Close the game completely and let Steam finish syncing.
2. Open the save folder above in File Explorer.
3. Copy the whole MoonSessions folder to another drive or a cloud folder you control.
4. Repeat before major patches, before switching branches, and before moving to a new PC.

If Steam reports a cloud conflict, compare the timestamps with when you last played on each PC before choosing which copy to keep.

Reviews, Player Counts and Known Launch Issues

Review scores moved fast in the first days. On October 24 the English store briefly showed Mixed, and by October 25 the listing read Mostly Positive, with 74% of 672 reviews positive. The game also passed 26,000 concurrent players on October 25.

The developer, a two-person team, posted an apology on October 24 acknowledging crashes, performance problems, multiplayer bugs, limited automation and progression balance. Patch 1.0.3 addressed several of these, and further fixes were promised.

The most common complaints in highly rated reviews are worth knowing before you pay:

• Upgrades top out early, and the remaining Moon is enormous, so late progress can feel slow.
• Buildings cannot be moved, and demolishing them refunds only part of the cost, which players report as 75%.
• Robot vacuums can miss dust under conveyor belts on uneven ground.
• The vehicle camera recenters at awkward angles.

Praise is just as specific: players like the relaxing cleaning loop, visible progress and the fun of the first hours with friends.

Before You Buy Moon Sweepers on Steam

Use this short checklist to avoid surprises:

• Your PC runs 64-bit Windows 10 or 11 and meets at least the minimum CPU and GPU list.
• You have a broadband connection, which both requirement tiers list.
• You are buying from the official Steam listing, app 5335510, published by DragDrop Games.
• You know whether you want the single game or the Brick by Brick bundle.
• If you play with friends, each person owns a copy and everyone is on the same version.
• You understand the late-game pacing complaints and are buying for the cleaning and automation loop, not a quick finish.

If those points fit, the launch discount window is the cheapest confirmed time to pick it up.
