Quick answer
Official store listings point to small-team online co-op, with Xbox listing 2-4 online co-op and Steam promoting four-player co-op plus cross-platform multiplayer. Treat local or couch co-op claims carefully: check the official store page for your platform before planning a shared-screen session.
Search intent notes
Player count is the main query
Searches like co-op player count and how many players usually need a fast answer before anything else.
Local co-op is a different question
Online co-op does not automatically mean couch co-op. A guide should not blur those together.
Crossplay can still have account friction
A store listing can support cross-platform multiplayer while invites, accounts, and patch behavior still need checking in real sessions.

Read the listing, not a copied summary
For player count and crossplay, start with Steam, Xbox, or the official platform page. These details can be updated during Early Access.
Plan for 2-4 online players
Small-team co-op works best when the team has one host, one shared base plan, and one agreed crafting target. Four players with no plan can burn through materials quickly.
Do not assume couch co-op
If you are searching for local co-op or couch co-op, verify the platform listing directly. Online co-op and split-screen co-op are not the same feature.
Check crossplay before a long save
If your group is split across stores or platforms, test invites and reconnects before building a serious shared base.
