Starsand Island Multiplayer Guide for Version 1.0
How Starsand Island 1.0 multiplayer works: unlock steps, host modes, passwords, permissions, coins, no crossplay, and why island progress is not shared.
Last verified: August 20, 2026 — Game version: Starsand Island 1.0 (launched August 18, 2026). Facts come from official Steam news, the community wiki, and dated player reports.
Starsand Island 1.0 multiplayer is a host-island visit, not a shared Stardew farm. One player hosts. Up to three friends join. Progress is not shared. The feature is locked until you finish a specific Island Life questline.
How to Unlock Multiplayer (1.0)
Player reports dated August 18–19, 2026, plus the Island Life wiki, agree on this tunnel. It is not available on a brand-new file.
| Step | What to do |
|---|---|
| 1 | Push Island Life on the phone |
| 2 | Reach Junior Talent and complete 5 Community Center bulletin requests |
| 3 | Unlock the Buy Land app |
| 4 | Buy or expand your land once and enter the Island Pro stage |
| 5 | Start the Smooth Sailing questline |
| 6 | Help Marston rebuild the Maritime Bureau |
| 7 | Finish / turn in Smooth Sailing |
| 8 | The Multiplayer app appears on the phone |
| 9 | Open it, pick a region/server, host or join |
A post on August 19 said you must finish Smooth Sailing before co-op appears. Launch-day suggestion threads already complained that rebuilding the Maritime Bureau is the gate. If the app is missing, you are still in this tunnel — do not reinstall first.
Host Modes
| Mode | Use it when | Console note |
|---|---|---|
| Anyone Can Join | Open island | Risky if you care about crops |
| Request to Join | You approve each visitor | Best default on PC |
| Password Required | Private group | Required for Switch 2 invites |
Official 1.0 news: farm, fish, explore, work profession quests, complete requests, take photos. Hosts can share crops, livestock, fishing, crafting, and other resources. Island progress is not shared. No cross-platform play at launch.
Multiplayer Coins and Shop
Together you earn Multiplayer Coins and spend them in the Multiplayer Shop. Confirmed categories: furniture, decorations, and other co-op-only items. A full name + price table is not yet confirmed — see Multiplayer Shop.
See 1.0 bugs if join mode resets. See Houseboat for the late-game boat home.
