Laboratories are full sets of crafting units packed together as one object.
Their main use is as rental, allowing players to just rent an space and use, instead of buying all the crafting units. Very useful for those that want to test the game before starting to play for real.
The laboratories will be available in a variety of models, that defines the units each laboratory will have, and also will have a built-in rental control, allowing you to rent your laboratories to other players.
The games main sim will have some laboratories available in the future.
Laboratories are still under development, they will be available some time after the game launch.
