Young Suns Co-op: Unlock Multiplayer After the Wednesday Introduction

Unlock the multiplayer menu and understand party size and personal progression.

Your next move

Multiplayer is locked during the introduction. Complete Send in the crowds at Wednesday: talk to Dian, open the noticeboard, and talk to Dian again. The welcome prompt then offers saving and returning to the title for multiplayer.

Why Multiplayer is unavailable at the start

The recorded title menu explicitly keeps Multiplayer unavailable until the introduction is finished. Begin in Single Player and follow the first departure route through the Wednesday noticeboard task.

Finish the introduction and return to the title

After the Send in the crowds completion notice, the welcome prompt says invitations are available from the title screen. Choose the save-and-return option to enter that flow, or continue singleplayer and return later. This footage verifies the unlock and entry point; it does not show a completed invitation or joining a friend’s session.

Group size and progress

The official Steam description supports one to four players, with personal progress carried between sessions. One player can fly while others craft or decorate, and the activities also support solo play. If you prefer to keep every task under your control, use the solo route for Cee-Eye-Why.

Choose a currently available store

Use the platform guide when planning a session. A feature listed for an unreleased storefront is not evidence of a joinable session today.
