Seamoth

The Seamoth is a small, versatile one-person submersible and spacecraft capable of sustained high-speed travel over considerable distances. It boasts an omnidirectional propulsion system that allows for lateral and vertical movement that gradually increases to a maximum of 11.25 m/s in any single direction. The speed in any direction is independent of other directions and can be added together using vector addition. Thus, if going forward and upward the maximum speed is 15.91 m/s (11.25 * √2) and if going forward, upward, and sideways the maximum speed is 19.49 m/s (11.25 * √3).

Cyclops

At 54 meters long, 12 meters wide and 14 meters tall, the Cyclops is the largest vehicle available and capable of diving to depths of 500 meters, or 1700 meters fully upgraded. It can be utilized as a mobile base, capable of being outfitted with furniture and other amenities using the Habitat Builder.

prawn suit

The Pressure Reactive Armored Waterproof Nano Suit Mk.III (abbv. PRAWN Suit Mk.III) is a bipedal mechanical walker, designed for use in extreme-pressure and zero-gravity environments. A plasteel-reinforced canopy of enameled glass protects the single occupant, and dexterity is provided by hydraulic limbs that are capable of striking with enough force to crush bone and pulverize rock. When not in use outside of water, the vehicle assumes a seated position.

Seatruck

The Seatruck is a modular undersea vehicle, somewhat resembling a submersible train. It consists of a small cab unit to which various modules can be attached to add additional functions. An unmodified Seatruck has a crush depth of 150m, which can be increased by outfitting it with depth modules.

Snowfox

While providing little protection for the pilot, the Snowfox can easily outmaneuver most threats, especially when upgraded with a jump module. Just don't try to take it over water.
