According to the developer Post-Launch Roadmap, this update will introduce multiplayer functionality, allowing up to four players to team up with friends, visit each other's islands, and participate in shared activities. Sign-ups for a pre-launch multiplayer test opened on June 26, 2026, with registration in groups of 2 to 4 players.44Multiplayer Has Been One Of77Multiplayer has been one of the most frequently requested features since Starsand Island entered Early Access in February 2026. The game currently plays as a single-player experience, with all island activities, NPC interactions, and progression handled solo. The cooperative play update will change that by enabling shared gameplay sessions with online co-op for up to four players.99Multiplayer was part of the vision for Starsand Island from early in development. During the Kickstarter campaign in 2025, Seed Sparkle Lab included multiplayer as a key feature on its Early Access development roadmap, with cooperative play scheduled for a mid-2026 update. The developer has emphasized that multiplayer is not an afterthought but a core pillar of the full release. This feature is not currently implemented in Early Access. All information in this article is based on developer roadmap announcements, Kickstarter updates, and official statements from Seed Sparkle Lab.1111Confirmed Co-Op Features1313The following table summarizes the cooperative play features that have been announced or referenced by the developer. Features marked as "Confirmed" have been explicitly stated in official communications, while others remain under consideration or unconfirmed.1515FeatureDetailsStatusOnline Co-OpUp to 4 players can play together online on a shared island sessionConfirmedIsland VisitsPlayers can visit friends' islands to tour farm layouts, houses, and decorationsConfirmedCooperative BuildingHosts set permissions for friends to build, move, or redesign parts of the islandConfirmedShared Farming and FishingFriends can help with farming, fishing, weeding, and daily chores togetherConfirmedSocial ActivitiesBike riding together, card games, and everyday social interactionsConfirmedMoonlit Forest Co-OpDungeon encounters designed to scale for teams with complementary rolesConfirmedHost-Only Story ProgressionOnly the host player progresses story quests; guests act as helpers during sessionsConfirmedCross-Platform Co-OpCross-platform online co-op referenced in Kickstarter materialsNot yet confirmedSplit-ScreenLocal split-screen multiplayerNot confirmedMini-Games (Poker, Mahjong)Additional social mini-games under consideration for post-launch updatesUnder consideration1717Island Visits1818Players will be able to travel to a friend's island and see their farm layout, house designs, decorations, and island development firsthand. This is a natural extension of the game's emphasis on creative building and decoration. Visiting another player's island lets you appreciate their work, get inspiration for your own builds, and share strategies for efficient farm layouts.2020The island visit system works with one player acting as the host and others joining their session. The host's island state, including time of day, season, weather, and NPC schedules, governs the shared experience. Visiting players can interact with the host's island, but they cannot make permanent changes without explicit permission from the host.2222Island visits tie into the Blueprint Library system. When visiting a friend's island, players can browse and download building designs, making it easy to share creative builds across the community. This creates a natural incentive for players to visit each other, beyond simply socializing or helping with tasks.2424Host and Guest Roles2626Cooperative sessions in Starsand Island follow a host-guest model. One player hosts the session on their island, and up to three other players can join as guests. The roles have distinct differences in what each player can do during a session.2828Host Privileges3030The host is the only player who progresses story quests and main questlines during a co-op session. This is due to the way the story is written and structured, and the developer has confirmed this is an intentional design choice rather than a technical limitation.The host controls island permissions, deciding which areas guests can modify, what building rights they have, and whether guests can move or redesign existing structures.The host's island state (season, time of day, weather, NPC locations) determines the environment for all players in the session.3232Guest Capabilities3434Guests can help with daily tasks such as farming, fishing, weeding, resource gathering, and ranching. They essentially act as helpers on the host's island.Guests can build and modify structures on the host's island, but only in areas where the host has granted permission. To keep things smooth, only one player can edit the same spot at a time, though multiple players can work on different areas simultaneously.Guests have access to the whole island, including the Moonlit Forest and any future DLC areas.Whether guests earn resources, experience, or progression credit for work done on the host's island has not been fully detailed. This remains one of the biggest open questions heading into the June update.3636Cooperative Activities3838Playing together opens up a range of shared activities that go beyond simple farm work. The developer has outlined several categories of cooperative gameplay.4040Farming and Daily Tasks4242Friends can work together on farming tasks, including planting, watering, harvesting, and weeding. Group farming sessions make large-scale crop operations much more manageable, and multiple players tending to animals at the same time speeds up the daily routine considerably.4444Exploration and Combat4646The Moonlit Forest features encounters designed to scale for teams. This puts emphasis on coordinated play and complementary roles. Tackling dungeon challenges with friends introduces new strategic possibilities that are not available in solo play. Players can cover each other during combat, split up to handle different objectives, and combine their efforts against tougher enemies.4848Travel and Vehicles5050Select vehicles and mounts will support multiple riders, allowing groups to travel together across the island. Bike riding together has been specifically mentioned as one of the social activities available in co-op sessions.5252Social Activities and Mini-Games5454Beyond work and exploration, cooperative play includes everyday social interactions. Players can sit together, hang out in decorated spaces, and enjoy leisure activities. Card games have been confirmed as a social feature for multiplayer sessions. The developer has also expressed interest in adding additional mini-games such as poker and mahjong in post-launch updates, though these are not guaranteed for the initial June release.5656Shared Progression5858How progression works in cooperative sessions is one of the biggest open questions. In single-player, your professions, currency, inventory, and relationship progress are all tied to your individual save. The developer has confirmed that story progression is exclusive to the host player during a cooperative session. Guests cannot advance their own story quests while visiting someone else's island.6060Seed Sparkle Lab has stated that multiplayer is designed around shared progression, collaborative building, and long-term cohabitation rather than simple drop-in visits. This suggests that the system will go deeper than a basic visiting mechanic, potentially allowing guests to earn some form of rewards or experience for their contributions. However, the specific details of what guests take back to their own save files after a session have not been fully revealed.6262The tension between meaningful guest rewards and preventing exploitation (such as farming resources on a friend's island and duplicating them at home) is a common challenge in cooperative farming games. How Seed Sparkle Lab solves this will be a key factor in how satisfying the multiplayer experience feels.6464Developer Statements and Community Response6666Seed Sparkle Lab has made it clear that multiplayer is a high priority. During the Kickstarter campaign, cooperative play was included on the official Early Access roadmap as a planned mid-2026 feature. The developer has repeatedly confirmed that co-op is not an afterthought, and that the team is taking extra time to polish the multiplayer systems before the 1.0 launch.6868The decision to hold multiplayer until June 2026, rather than adding it during Early Access, reflects a deliberate approach. By building on a stable single-player foundation with months of bug fixes and content updates already in place, the developer avoids the common pitfall of shipping a half-finished multiplayer mode. Community feedback has been largely positive about this approach, with many players expressing willingness to wait for a polished experience rather than receiving a rushed implementation.7070The most common community questions revolve around player count limits, cross-platform support, and guest progression. The confirmed four-player online cap has satisfied most requests, though some players have asked about local split-screen support, which has not been confirmed. Cross-platform play was referenced in Kickstarter materials but has not received a definitive confirmation for the June update.7272Timeline and 1.0 Release7474The cooperative play update is positioned as one of the last major feature additions before the game exits Early Access. The development timeline shows a clear progression of updates leading to 1.0:7676MonthUpdate FocusStatusFebruary 2026Early Access launch (single-player only)ReleasedMarch 2026Content updates, shop expansions, collaboration itemsDeliveredApril 2026Dating System and expanded NPC voice contentComing soonMay 2026Steam Workshop and MOD supportPlannedJune 2026Cooperative Play (multiplayer)PlannedSummer 2026Full 1.0 release on all platforms including Nintendo Switch 2 and PlayStation 5Planned77+MonthUpdate FocusStatusFebruary 2026Early Access launch (single-player only)ReleasedMarch 2026Content updates, shop expansions, collaboration itemsDeliveredApril 2026Dating System and expanded NPC voice contentDelivered.

Launching multiplayer alongside the 1.0 version gives the game a major selling point for players who have been waiting for co-op before purchasing. Each preceding update (dating system in April, mod support in May) builds toward a feature-complete game, with multiplayer serving as the capstone.7979Technical Considerations8181Adding multiplayer to a game originally designed as a single-player experience involves significant technical work. Network synchronization for real-time farming, building, and NPC interactions requires careful handling to avoid desync issues, lag, and save corruption. The developers' decision to schedule multiplayer as a late-stage addition gives them the benefit of a stable single-player foundation to build on.8383The permission-based building system introduces additional complexity. Ensuring that only one player can edit the same spot at a time while others work on different areas simultaneously requires a robust conflict resolution system. This is particularly important for preventing save corruption when multiple players interact with the same island state.8585Players on different platforms (Steam PC vs. Xbox Series X|S vs. future Nintendo Switch 2 and PlayStation 5 versions) may or may not be able to play together. Cross-platform play was referenced in Kickstarter materials, but a definitive confirmation for the June update has not been issued. This is a detail worth watching for in future developer updates.8787Related Articles8989MultiplayerPost-Launch RoadmapBuildingProfessionsMoonlit ForestBlueprint LibraryFishingFarmingKickstarter
