Over the weekend, Unknown Worlds revealed Subnautica's standalone Below Zero expansion would be with us in just a matter of days. Subnautica: Below Zero hits Early Access on January 30th. Details are scarce but we can tell you the system requirements for Below Zero are a definitive leap beyond the base game.

Subnautica: Below Zero Minimum System Requirements

  • OS: Windows 7 64-bit
  • CPU: Intel Core i3-530 2.9 GHz or AMD Phenom II X3 720 2.8 GHz
  • RAM: 8 GB System Memory
  • GPU RAM: 1 GB Video Memory
  • GPU: GeForce GTS 450 or Intel HD Graphics 530
  • DX: DirectX 11
  • HDD: 20GB Available Hard Drive Space

Subnautica: Below Zero Recommended System Requirements

  • OS: Windows 10 64-bit
  • CPU: Intel Core i5-4670 3.4 GHz or AMD Ryzen 5 1400 3.5 GHz
  • RAM: 8 GB System Memory
  • GPU RAM: 4 GB Video Memory
  • GPU: Nvidia GeForce GTX 1050 Ti or AMD Radeon RX 570
  • DX: DirectX 11
  • HDD: 20GB Available Hard Drive Space

Now,  these system requirements for Below Zero are subject to change so who knows, they may eventually end up sliding down to the same specs as the original Subnautica. In reality, though, we think Below Zero is going to be much more than a simple add-on for Subnautica. It's got the whiff of being a sequel in all but name only.

That being said, these preliminary specs for Subnautica: Below Zero aren't exactly going to trouble most folks. The minimum system requirements for Below Zero are pretty true to the name. Subnautica: Below Zero will run on just about any system provided you've got DX11 video card and a dual-core processor.

But, if you're wanting to enable all of those lovely water effects and whatnot, and get really immersed in Subnautica's aquatic world,  then you'll be a relatively modern low to mid-range system. The official recommendation is a graphics card with at least 4GB VRAM, along with a decently clocked 3.0GHz+ quad-core CPU. Subnautica: Below Zero will be launching in early access so performance could be spotty though and S:BZ will almost definitely be unoptimised.
