How to use the map with friends

  • Share a filtered map URL for the current resource, cave or route.
  • Use the coordinate calculator when one player is already near the target.
  • Keep spoiler-light on when one player is ahead of the group.
  • Split jobs: one player watches resources, one watches coordinates, one checks danger zones.

Common co-op checks

  • Make sure every player is on the same Early Access build.
  • Check platform account sign-in and privacy settings.
  • Restart after patches before assuming cross-platform play is broken.
  • Use official status channels for current service issues.
