What is shared
| Thing | Shared? |
|---|---|
| Money | Yes — one wallet for everybody |
| Buildings, robots, factories | Yes — the world is shared |
| Moon progress, flags, sites | Yes |
| Tools (brushes, brooms) | No — each player buys their own |
| Vehicles | Bought from the shared wallet; anyone can drive |
A friend who joins your mid-game save starts on the toothbrush even if you own the Extra Wide Broom. Use the shared money to buy them a broom straight away — a second Wide Broom user doubles your income immediately.
Splitting the work
- Sweeper: finishes hexes for region bonuses and keeps Packagers fed.
- Builder: carries the hammer, lays belts, builds sand and stone lines and solar.
- Driver: runs the best vehicle in long lanes once you have one.
- Explorer: collects flags and sites for early cash, later drops JONAS across the frontier.
With several players, a Packager per person in different directions works well — everyone feeds the same factory without walking home.
Co-op early game
- Everyone sweeps with brushes to reach the first brooms.
- Pool money for each player's Household and Wide Broom before any upgrade.
- One player buys the Building Tool and sets up Packagers; others keep sweeping.
- Rush the $800 Pressure Chamber + solar together.
Co-op late game
With JONAS running, spread out: each player takes a different direction from a different station, drops robots and hunts flags. The Crew Transport carries passengers, so one driver plus spotters is an efficient flag-hunting crew. Hexes robots clean near each player count toward that player's own help-clean achievements.
Achievement
