+# Upgrade Modules+ ++ +Upgrade Modules are software drives that improve the Cyclops, Seamoth, Prawn Suit, and Scanner Room.+ +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). Upgrade Modules for the Scanner Room are crafted at the mini-fabricator in the Scanner Room.+ +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. 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).+ +* **Cyclops:** Upgrade Modules can be placed in the upgrade console found in the engine room of the Cyclops. Six Upgrade Modules can be applied at once.+* **Seamoth:** Upgrade Modules are placed in a panel on the Seamoth's left side. Up to four Upgrade Modules can be applied at once.+* **Prawn Suit:** Upgrade Modules are placed in a panel on its top left. The Prawn Suit has four slots for Upgrade Modules as well as two purple-colored slots specifically for arm upgrades.+* **Scanner Room:** Upgrade Modules are placed in a panel inside the Scanner Room. Up to four Scanner Room Upgrade Modules can be applied at once.+ +## Upgrades Compatible with Seamoth and Prawn Suit+ +| Module | Image | Description | Compatible Vehicles |+| :--- | :---: | :--- | :---: |+| **Engine Efficiency Module** |  | Recycles heat by-product to minimize power inefficiencies.
