Is multiplayer limited to the playtest?
Not according to the later Next Fest announcement, which specifically makes co-op available in the demo and describes multiplayer optimization. Keep that announcement ahead of older playtest-only wording when checking whether friends can join the current downloadable demo.

How can players divide the work?
The store describes each player captaining a ship and sharing logistics, defence or exploration responsibilities. The team can also work toward the same objective together. Exact lobby limits and platform compatibility need separate confirmation rather than being inferred from the co-op label.
