Modification Station (Subnautica)
The Workbench is an in-development item that will be placed inside the Cyclops or inside a Seabase module. Its function is currently unknown. Workbenches will be constructed with the Builder. On trello there is talk about a Upgrade system, possibly leading to advanded tools such as Diamondblade, ultraglide fins, and high capacity tanks.
Recipe
The Workbench Blueprint can be obtained by analyzing the Workbench Fragment in the Fragment Analyzer. The Workbench currently cannot be constructed. The recipe is known from spawning in the workbench and deconstructing it with the builder.
