Playing Subnautica: Below Zero you’ll drown a lot. But is there a way of getting more oxygen so it happens less often? Read on.
The good news is that unless you’re playing Subnautica: Below Zero in hardcore mode, death only results in the loss of a few items. The blueprints and so forth you discover will stay, so if you swim down to the bottom of a chasm, scan an item for its blueprint, then die, the blueprint is yours to use.
But you can avoid drowning so much. Here’s what to do to get more oxygen in Subnautica: Below Zero:
Build an oxygen tank and upgrade it when possible
The bigger the oxygen tank, the longer you can stay underwater. A rebreather will also help if you’re diving down deep.
Refill your oxygen
There are three ways to do this:
- By surfacing either in the ocean or in an Architect cave, by swimming.
- By finding a oxygen plant (these get rarer the deeper down you go) and activating it, though you won’t be able to re-use that plant until it’s refilled.
- By finding an oxygen vent, which are far less common than they were in the original Subnautica and hanging around it till the bubbles bump into you.
Build a Sea Glide
A Sea Glide will let you swim faster and still grab items such as titanium, gold etc. It’ll also get you to the surface quicker if you’re running out of air – the faster you’re swimming, the more you can get done with the same amount of oxygen.
Wait until your oxygen meter has been refilled
This may seem obvious but Subnautica: Below Zero isn’t like most games; you don’t refill your lungs and tanks the second you surface. Wait until your oxygen meter is full, otherwise you’ll be diving down with less than a full tank.
Build an enclosed vehicle
Vehicles do have crush depths, the lowest point they can go without breaking, but they’re great for refilling oxygen. So if you want to explore the depths, build a Sea Truck, then go down as far as you can before you hit crush depth. You can then dive down and swim back to it to refill your oxygen meter
And there you go. Happy not-drowning!
