Solarpunk update 1.3.0 adds crossplay and Lost Cargo

Solarpunk update 1.3.0 went live on Steam on September 30, 2026, bringing crossplay, Lost Cargo drops, a storage rework, an expanded character editor, and UI scaling to Cyberwave's floating-island survival game. The Steam build is ready now, but console versions are still waiting for platform-holder approval and rollout as of October 1, 2026. Cyberwave calls it "our first bigger update since release."

Key Takeaways

• Steam crossplay is live, with invite codes, a player list, host kick and ban controls, and a new multiplayer interface.
• Every player in a session must be on the same version.
• Console versions are later, pending approval and rollout. No exact console date is given.
• Lost Cargo can contain the Big Chest, Roof Solar Panel, Wall Foliage, In Game Radio, and Snap Connector.
• Storage, character customization, UI scaling, decoration, and fishing all changed.

Solarpunk update overview

Solarpunk released on June 8, 2026. Steam lists Cyberwave as developer, rokaplay and Metaroot as publishers, the Windows version, and a US price of $22.99. Steam currently shows Very Positive across 4,587 total reviews. The Solarpunk game review covers the launch verdict.

This Solarpunk update closes the biggest gap in the Solarpunk roadmap, then reaches into storage, customization, the interface, decoration, and fishing.

What Happened in the Solarpunk update

The patch notes for version 1.3.0-304818 were posted at 10:36 UTC on September 30, followed by Cyberwave's announcement at 15:06 UTC.

Crossplay is now available in the Steam version. Players can join through invite codes, view the player list from the in-game menu, and let hosts kick or ban players. Cyberwave also updated the multiplayer UI. Every player must be on the same version.

Console versions are waiting on platform-holder approval and rollout, which the announcement says can take a few days. It gives no date for any specific console, so 1.3.0 is confirmed live on Steam only as of October 1, 2026.

Lost Cargo drops can appear during regular gameplay. They can contain the Big Chest, Roof Solar Panel, Wall Foliage, In Game Radio, and Snap Connector, with map markers, messages, and sound effects.

Chests now support different storage sizes and names, and storage can be placed in nightstands, commodes, and crates. A larger chest adds capacity. The Character Editor gets new options, while UI Scaling covers several major interfaces. Nintendo Switch 2 and Steam Deck default to Large UI.

Non-shared worlds were removed. Players can now collect postcards for the Postcard Pinboard, place flower patches, vines, ivy, glowing plants, Sakura trees, and Jacaranda trees, and use an In Game Radio that plays the main menu soundtrack. Roof solar panels, connector holders, new fishing loot, a higher Starter Island cotton chance, and the Fishing Drone rename are also included.

Fixes cover looping thunderstorms, the Electrical Research Station, save file names, Character Editor settings on the airship, achievement fallback, a standing torch offset, and Dock placement. Smaller changes adjust the Food Basket unlock, remove decorative pans from the Kitchen recipe, and grant missed research unlocks.

Why It Matters

For co-op groups, this Solarpunk update removes the launch version's same-platform barrier. Crossplay still has a version check, so Steam and console players may need to wait until the console build catches up. The studio has not published an exact date.

Several roadmap lines are now out of date. The patch delivers crossplay, storage-enabled furniture, expanded customization, roof panels, postcards with a display board, and decorative plants, and the roadmap's late-September target has passed. The announcement points to Feature Voting work next, including an Airship overhaul with multiple seats and sitting on furniture.
