The endgame for the tech tree in Lamplight Station involves the ability to build a lot of complex and high-tech machinery. Things like stellarators, gene splicers and molecular printers are on the horizon. Most of these machines will require power, cooling and item inputs. This also allows for a lot of creativity, because the player can decide how to lay out these structures optimally, and automating them can become a possibility.
You have to walk before you can run, so some of the first multiblock structures that the player can craft will be much simpler.
Fog Collectors
These allow for the collection of moisture from the air, and built using two parts: A water barrel, and one or more collector blocks.
The collectors can be stacked vertically over a single barrel, at a slight efficiency penalty. Water can be collected from the barrels by the player for other uses.
Tier-II water barrels will be able to pipe water elsewhere for use in irrigation, cooling, etc.
Composter
Water is primarily useful for growing plants. It will be a challenge to even get started growing plants in such a harsh environment. Dirt is not available and must be created from ingredients scrounged from the level. Biomatter can be inserted into another craftable machine: the Improvised Composter, which will output key ingredients for creating soil.
As more machines become available during the development of the game, the possibilities for combining and using them creatively expands.
