What each player can do here
- Gatherer: holds the axe or the pickaxe, carries wood and iron to the Storage wagon, and grabs the bucket when the engine runs hot.
- Track layer: takes finished track off the Crafter, lays it ahead of the train, clears the path when no track is ready and deals with the creatures.
If your skill levels differ: The wiki and Blueprinted both say only one player should lay track, and a lower difficulty means more resources and less unbreakable rock.Our suggestionWhen skill levels differ: give track laying to the steadier player, and let the newer player own one tool and keep resources coming. How to split the roles
Oxygen and flying
Part 1 of 2. Water becomes air.
- BothThere is no water. The Tank wagon and the bucket each make an oxygen bubble.
- BothIf your oxygen runs out you die and respawn.
- BothJetpacks let you fly between islands, so bridges only need to carry the train, and they are stone.
- BothSpace has no night, which leaves the Light wagon with nothing to light.
Meteors and scarce resources
Part 2 of 2. The space hazards.
- GathererMeteors crash down now and then and wreck terrain and track outside an air bubble; hold the bucket up to block one.
- Track layerSound is muffled, including the crash warning, so watch the train's position and speed.
- BothResources are scarce; mine everything you pass and build as tightly as you can.
