Description

The Cyclops is a vast industrial-use submarine that functions as both a vehicle and a mobile base. At 54 meters long, 12 meters wide, and 14 meters tall, it is the largest vehicle available in the game. It can dive to depths ranging from 500 meters (base) to 1700 meters (fully upgraded with Depth Modules). The Cyclops features an onboard AI that warns of danger, a beacon for location tracking, and a docking bay capable of storing a Seamoth or Prawn Suit.

Overview

Access to the Cyclops is obtained via the dive chamber located at the bow of the keel or via the docking bay when piloting a Seamoth or Prawn Suit. The submarine acts as a cross between a Seabase and a vehicle; players can walk freely inside but only control movement when approaching the helm. The helm controls forward/backward movement, ascent/descent, and turning, though the Cyclops cannot strafe or pitch like the Seamoth.

Interior Layout

  • Bridge: Located at the bow, featuring a large domed glass port for navigation. Contains the main HUD, damage indicator, and controls for lights and color schemes.
  • Upper Midsection: Accessible via bulkhead doors from the bridge. Contains the vehicle bay access console and decoy tube loading port.
  • Engine Room: Located at the stern. Houses the engine, six Power Cells, and the upgrade fabricator. Narrow passageways exist on either side.
  • Keel Section: Contains five built-in Storage Lockers and the diving chamber hatch for embarking/disembarking.
  • Aft Section: Connects the Engine Room and Vehicle Bay, offering limited wall space for small items.

Helm HUD

When piloting, the following information is displayed:

  • Depth Indicator & Engine Power: Top-center display showing current/maximum depth and engine power percentage.
  • Compass: Bottom of the window, attached to steering controls.
  • Speed Settings: Upper-left panel. Three settings: Slow, Standard, and Flank. These affect speed and noise emissions.
  • Health & Noise: Lower-left bars showing hull integrity and creature attack/fire warnings.
  • Cameras & Silent Running: Right-side panel for toggling external cameras, silent running mode, and the Decoy Launcher.
  • Threat Indicator: Holographic projector showing nearby hostile creatures (red triangles) and decoys.
  • Proximity Indicator: Warns if the hull is close to terrain.

External Cameras

Three external cameras are located on the keel (below), sail (above), and screw (rear). They provide directional lighting and allow the pilot to view surroundings while maintaining control. Cameras are essential for navigating obstacles and checking for predators.

Construction Recipe

The Cyclops is crafted using the Mobile Vehicle Bay. It requires the following components:

Plasteel Ingot Enameled Glass Lubricant Advanced Wiring Kit Lead

Blueprints and Fragments

Unlike most blueprints, the Cyclops requires finding and scanning three different sets of fragments to craft its components. Each set requires three fragments to complete, progressing the blueprint by 33% per component (9 fragments total).

Cyclops Hull Blueprint

  • Fragments Needed: 3
  • Locations: Seabed, Mushroom Forest, Sea Treader's Path, Wrecks (Northwestern Mushroom Forest, Sea Treader's Path).

Cyclops Hull Fragment

Cyclops Engine Blueprint

  • Fragments Needed: 3
  • Locations: Aurora, Seabed, Crag Field, Crash Zone Trench, Mountains, Wrecks (Mountains, Underwater Islands).

Cyclops Engine Fragment

Cyclops Bridge Blueprint

  • Fragments Needed: 3
  • Locations: Seabed, Crash Zone Trench, Mushroom Forest, Sea Treader's Path, Wrecks (Northwestern Mushroom Forest, Sea Treader's Path).

Cyclops Bridge Fragment

Note: While the East side of Mountain Island contains many fragments, it is heavily patrolled by Reaper Leviathans and Bonesharks at depths below 200m. Safer alternatives include the Mushroom Forests for hull/bridge parts and the Crag Field for engine parts.

Upgrades

The Cyclops can be modified with various modules installed via the Upgrade Console in the Engine Room. Common upgrades include:

  • Depth Module MK1/MK2/MK3: Increases maximum diving depth.
  • Sonar Upgrade: Enhances detection range.
  • Shield Generator: Provides defensive shielding against fauna attacks.
  • Fire Suppression System: Automatically extinguishes fires.
  • Docking Bay Repair: Repairs docked vehicles over time.
  • Decoy Tube Upgrade: Increases decoy capacity from 1 to 5.
  • Engine Efficiency: Improves power consumption.
  • Thermal Reactor: Allows charging via thermal vents.

Docking and Maintenance

Players can dock a Seamoth or Prawn Suit in the central vehicle bay. Docked vehicles recharge their batteries using the Cyclops' power cells and are automatically repaired if the Docking Bay Repair Module is installed. The Vehicle Bay doors close automatically upon docking or undocking.

Audio Cues

  • Ping: Standard sonar ping sound.
  • Abandon Ship: Music played when the Cyclops is on fire.
  • Leviathan: Music played when a Leviathan attacks.
  • Red Alert: Alarm sound during active threats.
  • Seamoth: Sound associated with Seamoth interactions.
