How to Swim Faster in Subnautica: Below Zero

Subnautica Below Zero

Are you swimming around in Subnautica: Below Zero but finding it slow going? Here’s what you can do to speed things up.

Swim speed matters in Subnautica: Below Zero. It’s not so much that you need to outswim hungry creatures, though that is a factor. Speed matters because you have a limited supply of oxygen; the faster you can swim, the faster you can reach the surface, or the next oxygen plant, before your air runs out.

There are a few ways of increasing your swim speed. Here’s what to do:

  • First, craft a pair of Fins. You have the recipe to create these right away and, when you create a modification station later in the game you can upgrade them to Ultra Glide Fins. Both will give you a significant, but not enormous speed boost.
  • Secondly, you can craft a Booster Tank. You need to first discover this technology in an underwater cache but, if we’re honest, don’t bother. It lets you go faster but it uses your oxygen supply to do so. If you’re trying to reach the surface before you run out air, using the booster tank is hardly going to help.
  • Finally, and this is the biggest speed boost, build a Sea Glide. You can find the parts of the Sea Glide within swim range of your your starting position. Scan the parts, then build the Sea Glide and you can swim at quite a rate. We say ‘swim’ but you’re really being pulled along, but since you’re not inside a vehicle, you can grab things easily.

You can also build other vehicles, such as the Sea Truck and Sea Prawn but if you want to be able to pluck resources quickly than swim back to safety, the combination of Fins and a Sea Glide is the way to do it.
