#SUBNAUTICA GUIDE 2016 AIR SAC MODS#
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.
