Single-player
Describes a session built around one player. The number of characters visible in that world is a separate matter.
Know the difference between a busy world, library sharing and another person joining your game.
Last checkedSteam lists single-player; no co-op announcement was found in the reviewed sources. Treat a shared colony as an unconfirmed feature when deciding how you want to play.

Would let multiple people participate in shared gameplay. To judge it, you need details such as player count, local or online support, and how joining works.
Appears among Steam’s listed features, but concerns library access. It does not establish that two players can enter the same colony.
Look for an explicit developer description of another human player joining a session. A group of characters following commands, two names in a video title or a community request does not answer that question.
If support is announced later, check the version and platform as well as the mode. Online co-op, local shared-screen play and a planned experiment are different commitments.
The reviewed sources do not document a shared player session. Do not plan a co-op purchase around footage of multiple colony characters.
No. Library sharing and simultaneous play inside the same game are different features. Check the game's own play-mode description for co-op support.
A command system describes how you direct characters. On its own, it says nothing about lobbies, invitations, networking or a second player joining.
It is not a confirmed commitment in the sources reviewed. A future announcement would need to specify the supported mode and version before this guide changes its answer.
