Building the Cyclops in Subnautica marks a major turning point in your ocean survival journey. This massive submarine functions as a mobile deep-sea base that allows players to venture safely into hazardous underwater biomes. To construct this impressive vessel, players must systematically locate required blueprint fragments and gather specific crafting materials.

Unlocking the Cyclops Blueprint Fragments

Unlocking the Cyclops requires scanning nine total fragments divided across three distinct blueprint categories. Players need three hull fragments, three bridge fragments, and three engine fragments to assemble the complete schematic. Searching distinct biomes like the Mushroom Forest, Sea Treader's Path, and the crash site around the Aurora will yield these essential scans.

Using a Scanner Room in biomes like the Mushroom Forest drastically speeds up the process of discovering hidden fragments. Equipping a fast vehicle like the Seamoth ensures you can explore dangerous areas without running low on oxygen. Once all nine scans are registered in your PDA, the vehicle becomes available to construct at the Mobile Vehicle Bay.

Gathering Necessary Crafting Resources

Fabricating the Cyclops demands a substantial collection of advanced crafting materials. The full recipe requires three Plasteel Ingots, three Enameled Glass, one Lubricant, one Advanced Wiring Kit, and three Lead. Collecting these items requires exploring both shallow reefs and deeper cave systems rich in metal ores.

Plasteel Ingots require combining titanium ingots with lithium, which can be found along rocky walls and deep seabed crevices. Enameled glass relies on stalker teeth and glass, forcing players to venture near kelp forests to collect the necessary components. Preparing your inventory with organized storage containers before starting resource gathering prevents unnecessary back-and-forth trips.

Constructing the Submarine at the Mobile Vehicle Bay

With all materials and blueprints secured, you must deploy a Mobile Vehicle Bay into open water. Ensure that the vehicle bay floats in a sufficiently deep area so the submarine has enough room to spawn safely. Interacting with the vehicle bay menu allows you to initiate the automated construction process instantly.

Once deployed, the Cyclops drops into the water and stands ready for immediate boarding through its bottom hatch. It comes equipped with onboard power cells, internal wall lockers, and docking capabilities for smaller vehicles like the Seamoth or PRAWN Suit. Installing essential depth upgrades right away guarantees that your new submarine is prepared for extreme depths.

Key Upgrades and Deep-Sea Preparation

Operating a Cyclops successfully requires careful management of power and structural integrity during long journeys. Prioritizing the Cyclops Depth Module MK1 allows you to venture far deeper into pitch-black trenches and cavern systems. Crafting additional upgrades like the Engine Efficiency Module and Sonar system will drastically improve navigation and energy conservation.

Keeping spare power cells inside internal storage lockers ensures you never get stranded during extended oceanic expeditions. Installing fabricators and extra storage compartments inside the submarine turns it into an effective self-sustaining base. With proper preparation and resource management, the Cyclops serves as your ultimate ticket to exploring the deepest secrets of Planet 4546B.
