Sweep The Moon Shared Money and Co-op Guide

You can clean the moon with up to four friends, working together toward 100% Moon Cleaned. Permanent game passes work on moons you play, including a friend's moon.

A crew member can use their own Cash to buy an upgrade that helps everyone. Decide who can afford the next purchase while leaving enough Cash for the equipment each player needs.

For a shared build, start with the automation setup. Compare the garden and panels in the passive income guide.

• Head Start: Once per moon, a fully paid walk-behind sweeper appears in the first empty vehicle bay. Crew members can drive it. If every bay already has a vehicle, no Head Start sweeper is supplied on that moon.
• +1 Robot Dock: The owner can place one small dock for free on each moon; its robots clean for the whole crew. Pick it up to place it again for free.
• 2x Cash: The owner receives a +100% Cash bonus on hand sweeping, driving, completed tiles and their share of automation. The bonus adds to payout upgrades and does not double Cash packs.
• Sell As You Sweep: The owner is paid as dust enters their canister and while a vehicle they drive sweeps.
• Fast Vehicles: The owner gets +30% driving speed in any vehicle they drive.

See the game pass guide for prices and purchase choices.

Assign jobs according to what the crew needs now, then switch when a raid or a processing backlog needs attention:

• Cleaner: Keep clearing dust while robots and drones work. Use the Head Start sweeper if one is available.
• Builder: Spend personal Cash on shared robots, drones and income facilities. At the Crew Robot Bay or Drone Pad, press E at the upgrade prompt and buy the next unit if you can afford it.
• Landmark and processing support: Clear access to useful towers and activate them. The East and South-West Radio Towers each add +0.1x Cash per sale for the crew. Watch the Lunar Converter and upgrade it when processing falls behind.
• Raid responder: Use a Ray Gun against approaching goblins. If the Lunar Converter is damaged, hold E at the available repair prompt to restore it.

In a smaller crew, combine building, landmark work and defense into one support role, returning to cleaning between jobs. The landmark guide covers bonus choices, and the raid guide covers protecting the base.
