Overview
Multiplayer in Outbound supports up to four players in online co-op. All players share the same camper van and work together to gather, build, craft, and explore. The game is fully playable solo, with co-op available as an optional layer on top of the single-player experience. Multiplayer was included in the alpha build, was available in the free Steam demo, and is part of the full 1.0 release.
Session Structure
One player hosts the game, and up to three friends join the host's world. Sessions are drop-in/drop-out: friends join and leave at any time without interrupting the host's progress. The world state, van configuration, and progress persist with the host's save file. Joining players do not bring their own vans; everyone shares the host's vehicle. Save model details for joining players (whether progress carries to a player's solo file) have not been publicly confirmed by Square Glade and are subject to in-game testing.
Invitation System
Co-op is friends-based and uses an in-game multiplayer code rather than a public lobby browser or matchmaking. To host, start or load a save, open the pause menu with Escape, go to Multiplayer, and choose Show Multiplayer Code. Share that code with the people you want to play with.
To join, a friend launches the game, selects Join Friend, and enters your code. Up to three friends can drop into the host's world this way, and sessions remain friends-only with no public server browser.
One requirement catches groups out: every player, the host and all joiners, must finish the short opening tutorial in their own save before co-op will work. Completing that first area is also what unlocks multiplayer in the first place, so if a friend cannot connect, make sure they have played through the intro on their end first.
Region Selection
Outbound supports explicit region selection when creating a multiplayer session. The host can pick a server region directly when opening a session, or leave the setting on Automatic, which selects the closest available region. Players who experience repeated disconnects or high latency on the default region can switch to a closer one and re-host the session. The region picker was added in a launch-week patch in response to reports of connection drops in certain regions.
Crossplay
Outbound does not support crossplay between PC and consoles. Square Glade has confirmed publicly that cross-platform play is not part of the launch feature set: the studio's exact wording on the official Steam Community discussion thread was that there will be no cross-play support to play with friends on consoles. Each platform's player base is its own pool, so a Steam player cannot join a PlayStation 5 host, a Switch host cannot invite an Xbox player, and a Switch 2 player cannot join a Switch 1 session. Crossplay has not been announced as a post-launch feature, so groups of friends should buy on the same platform if they want to play together.
Local and Split-Screen
There is no local co-op and no split-screen support. All multiplayer play is online over the internet. Two players sharing a couch on the same console cannot play Outbound together unless each has their own console and copy of the game.
Co-Op Activities
Outbound features no combat, so co-op is built entirely around cooperative exploration, gathering, building, and managing the shared van. Players can split up to gather resources from different parts of a biome, coordinate cooking and recipes, or work together to lay out the camper interior. The dog companion appears for each player in their own session and does not require co-op coordination. A launch-week update added automatic material deposit for the dog companion, so the companion drops gathered items into nearby storage without manual intervention from the player.
Demo and Save Carryover
The free demo supported the same online co-op as the full game. Demo save data does not transfer to the full release, so co-op groups that played the demo together start fresh on launch.
Stability and Patches
Several launch-week patches addressed multiplayer issues that surfaced in the first days of the public release. The most disruptive was a host-visibility bug where the hosting player would become invisible to their peers after stepping out of the camper van, which broke coordination for shared crafting, cooking, and exterior building work. The host is now correctly visible to joiners after exiting the vehicle, restoring the intended co-op flow.
Subsequent patches resolved additional multiplayer issues: achievement-unlock timing in co-op sessions, elevator stability when multiple players use lifts, fall damage incorrectly applied when joining a session in progress, multiplayer issues with bee hives and water catchers, and the host-disconnect handling. The studio also added in-game error codes for multiplayer-connection failures, so players seeing a connection error can report a specific code rather than describing symptoms. The version history article tracks the full per-patch list.
Recommended Setup
Co-op runs over the host's connection. A reliable home internet connection on the host's side is more important than the joiners'. Players who experience desyncs in van interiors or interaction with workstations should check the frequently asked questions article for current known issues and workarounds.
