In those cases, the base-level module is crafted at the mini-fabricators described above, but then improved individually at the Modification Station (not to be confused with the Vehicle Upgrade Console mentioned above). Note that a few upgrades are compatible with both the Seamoth and the Prawn Suit, and both the Seamoth, Prawn, and Cyclops Depth Modules are themselves upgradeable.
Upgrade Modules for the Cyclops are crafted at the mini-fabricator in the Cyclops' engine room, Upgrade Modules for the Seamoth and Prawn Suit are crafted at the mini-fabricator in the Vehicle Upgrade Console (formerly referred to as the Vehicle Modification Station), and Upgrade Modules for the Scanner Room are crafted at the mini-fabricator in the Scanner Room. Upgrade Modules are software drives that improve the Cyclops, Seamoth, Prawn Suit, and Scanner Room.
