Subnautica: Below Zero Early Access

Unknown Worlds announces Early Access is now underway as promised for Subnautica: Below Zero, the sequel to Subnautica, their waterlogged action game. They offer a new Early Access Trailer with a look, along with an odd sales pitch based on the game's shortcomings: "Below Zero is not finished - This frozen underwater adventure is a work in progress. As we did with Subnautica, we are building Below Zero out in the open. With your help, we will craft a worthy follow up to the original game. Below Zero is full of bugs, runs poorly, and includes only a small portion of our planned features. It's also a game we're excited about. If you join us, we think you might enjoy this journey through Early Access." For those who want to wait until they overcome all that, they suggest signing up for their Development Newsletter to keep up with its eventual full release. For the undaunted, here's more on the game:
Dive into a freezing underwater adventure on an alien planet. Set one year after the original Subnautica, Below Zero challenges you to survive a disaster at an alien research station on Planet 4546B. Craft tools, scavenge for supplies, and unravel the next chapter in the Subnautica story.
