The Cyclops is so large that you can dock another whole vehicle inside it, such as the Seamoth or Prawn suit. While Seamoth is the size of a single seat and has no bonus inventory, the Cyclops is massive and has a large, multi-level interior space in which you build base facilities and store items. You can also add storage space to the vehicle in order to increase the yields of each foray. The Seamoth can initially dive to 200 meters underwater (crush depth), and can be upgraded to dive deeper. Since the Seamoth has an oxygen atmosphere interior, you can park it at a significant depth and then free-dive away from and back to it to acquire resources - a gathering tactic that's substantially faster than returning to the surface. You'll need protection against heat to enter these areas.

Some areas of the game are extremely hot, and the temperature of the water can reach near-boiling. You will need protection against radiation in order to enter these areas. Some areas of the game are polluted with radiation.

Finding better vehicles or improving vehicle crush depths with vehicle mods is required to progress further. Although the player can free-dive at any depth (to our knowledge), all vehicles have limited "crush depths," beneath which, they will take periodic damage. The deeper you descend into the ocean, the greater the pressure is. The player's personal oxygen supply gates how long you can free-drive away from an oxygen source. Other oxygen resources commonly include player constructed bases, vehicles, or pipe systems. While away from base, the basic free-diving game loop involves descending below the surface, exploring, gathering resources, and then returning to the surface (or another oxygen resources), then diving again. There are multiple tiers of oxygen tank available.

When you're free diving, the more oxygen you can carry, the deeper and longer you can dive.Oxygen length can be improved by equipping oxygen tanks.

You can choose to bring these resources with you to extend your trip, and you can eventually create more bases or mobile bases to extend your range even further. Food and water gate how long you can be away from base. The basic game loop involves departing base, finding resources, bringing them back to base, crafting/upgrading, eating/drinking, and then departing base again. Since you can initially only cook food and create water in base, Hunger and Thirst are effective constraints on how long you can explore without returning. To survive, the player needs to eat and drink. Progression in Subnautica proceeds along certain dimensions - how long a limited resource lasts, and how much or how long you can withstand a limiting aspect of the hostile environment.
