Co-op & cross-platform multiplayer: what Steam confirms

Steam labels the full game with Online Co-op and Cross-Platform Multiplayer. The developer's demo starter guide says you can play solo or join up to four other players through Steam invites or a session code. The listings do not name supported platforms or prove every cross-platform combination works in the current Demo.

Can I play with friends?

Yes, within the limits described by the developer. Its Getting Started post says to play solo or team up with up to four other players, then invite friends through Steam or share your session code. The current full-game Steam listing also labels the product Online Co-op. These sources establish that co-op is an intended feature; they do not describe matchmaking, a public-server browser or every party restriction.

What does Steam mean by cross-platform multiplayer here?

The full game's Steam feature list includes Cross-Platform Multiplayer. Steam does not identify the platform pairs, account-linking rules, regions or progress-sharing behavior on that listing. The full game is still listed for Q4 2026, so this label should not be rewritten as proof that any particular console and PC combination works in the Demo.

Confirmed versus not yet established

TopicDocumented detail
Officially listedSingle-player, Online Co-op and Cross-Platform Multiplayer appear on the full game's Steam page.
Starter-guide party informationSolo play or up to four other players; Steam invites or a session code are named ways to join.
Not established by these sourcesWhich devices can connect together, whether a given cross-play pairing works now, dedicated servers, progression sharing or controller compatibility.

Before you invite a group

  1. Confirm that everyone is using the same current Demo build and can see its multiplayer option.
  2. Use the in-game prompt and current Steam listing if they differ from this dated reference.
  3. Do not assume that the full game's cross-platform label answers a particular device-pairing question.

Why this page is deliberately narrow

We have not run a cross-platform session or independently tested party limits. This page separates what the developer and Steam currently label from questions that need platform-specific evidence, rather than turning a feature badge into an unverified setup guide.
