Direct answer
Starsand Island multiplayer is a host-based guest system in 1.0 with unshared island progress and per-resource permissions; player and reviewer reports say access is gated behind single-player progression, with exact unlock rules Pending confirmation.
Direct answer
The collected material describes Starsand Island multiplayer as a host-based guest system rather than a fully shared farm. One player hosts their island and friends join, island progression is not shared, and certain quests are tied to the island where they are started, so visiting a friend does not merge permanent progress. The host controls who can join and what guests can use, and cross-platform play is not supported at launch.
How multiplayer works
The host sets access to Anyone Can Join, Request to Join, or Password Required, and on Nintendo Switch the password option is required to invite friends. Co-op covers farming, fishing, exploring, working on profession quests, and completing requests together. The host manages separate permissions for crops, livestock, fishing, crafting, and other resources, and can change them at any time, so guests cannot steal from a farm without permission.
Players earn Multiplayer Coins by doing activities together, including farming, fishing, exploring, and even taking photos, then spend them in a special Multiplayer Shop. The devs have said they are exploring cross-platform multiplayer in the future but warned players not to buy expecting it at launch. Updates may also arrive on PC before consoles because of platform review processes.
Unlock and reception
Multiple player and reviewer reports say multiplayer is locked behind hours of single-player progression. One reviewer says it is gated behind the Island Life quest and a phone app unlock, and another Switch 2 review says players must finish each profession's beginner quests (roughly 4-5 hours) before they can host three others. These are reported conditions, not an official checklist, so the exact unlock rule remains Pending confirmation.
gamesradar reports that 1.0 reviews turned negative, with recent Steam reviews mixed and 61% of launch-day reviews negative, citing allegations about undisclosed AI, Tencent funding, undelivered Kickstarter keys, and a day-one DLC priced at $20 that a reporter called a recolored $100 Kickstarter tier. The same report says multiplayer is locked behind hours of single-player gameplay and that progress is only awarded to the host, and quotes a Reddit comment that there is nothing worth coming back for. This page attributes those claims to the report and the player comments rather than confirming them.
What official material confirms
The launch material and official site describe online multiplayer for up to four players. The supplied research does not confirm cross-platform play, local split-screen, universal password rules for every platform, or a complete host permission list. Any detail not supported by a direct official source stays Pending confirmation, and this page does not invent an unlock order or a co-op feature list beyond the material.
