|This article is about Cyclops Engine Efficiency Module for the Cyclops. You may be looking for Engine Efficiency Module which is for the Seamoth or the Prawn Suit.|
The Cyclops Engine Efficiency Module is an upgrade module that increases the engine efficiency of the Cyclops by 300%. It does not affect the energy usage rate of anything besides moving the Cyclops (other modules, attached devices, or recharging vehicles).
A single Cyclops Engine Efficiency Module can be found in the Aurora's drive room, located inside of a console. Obtaining this module unlocks its blueprint, allowing further modules to be crafted. By simply crafting the Cyclops, this module can be unlocked as well. The Cyclops Engine Efficiency Module can only be crafted by the Cyclops Upgrade Fabricator.
This upgrade does not stack.
- The item description used to say "Just for you, Jacksepticeye!", a nod to streamer and Youtuber Jacksepticeye, who helped popularize the game, and specifically a reference to a video where he complained that the Cyclops' power drained too quickly.
- It was previously called the Power Efficiency Module, and would have the same effect on all power-draining functions of the Cyclops. This was changed at least in part due to an exploit wherein a Power Cell Charger installed on the Cyclops used less power to charge a cell than the cell contained, allowing for infinite energy.
