What the developers have to say:

Why Early Access?

“Some games are built inside boxes. No one can see inside the box, they can't enjoy the game while it is being built, and its strength depends completely on the skill of the people inside the box. Other games are made out in the open in full view, with countless people contributing to them in innumerable ways. They can be enjoyed while they are pieced together. At Unknown Worlds, we like making games in the open. It's more fun that way, and we think it makes better games.”

Approximately how long will this game be in Early Access?

“Subnautica will most probably be in Early Access for a significant portion, or most of 2015. There a reasonable chance that it will be longer, or shorter. Members of the Subnautica team have differing ideas about how what exactly will be done before Early Access finishes, and the scope of work to be done (and therefore time needed) will be heavily influenced by your feedback during the Early Access process.”

How is the full version planned to differ from the Early Access version?

“Early Access is a nucleus around which a better, bigger, and more fun game can form. Lots of the core elements of Subnautica gameplay are already in place. Over time the world will grow larger, deeper and more striking, creatures more diverse and intelligent, loot, crafting and vehicle construction more comprehensive, the story more fleshed out, and ecosystems richer and more vibrant . Large submarines, new unique life forms, and fantastic environments are all in production and will be introduced to Subnautica Early Access in updates.”

What is the current state of the Early Access version?

“Subnautica is absolutely playable and relatively stable right now. There is at least one hour of adventure content available for play right now. Before going on Early Access, Subnautica was publicly available and playable for two months. In this time, significant work was done to ensure that the game is in a state to stand up to the demands of Early Access.”

Will the game be priced differently during and after Early Access?

“Subnautica's price might go up, down, or stay the same during and after Early Access. We don't expect it to change, but the possibility is there.”

How are you planning on involving the Community in your development process?

“Open development is everything to Unknown Worlds. Here's how you can get involved in, influence, and be a part of Subnautica's development:

About This Game

Subnautica is an open world, underwater exploration and adventure game currently under construction at Unknown Worlds, the independent developer behind Natural Selection 2.

Dive Into a Vast Underwater World




After crash landing on an alien ocean world, the only way to go is down. Subnautica's oceans range from sun drenched shallow coral reefs to treacherous deep-sea trenches. Manage your oxygen supply as you explore Kelp Forests, plateaus, reefs, and winding cave systems. The water teems with life: Some of it helpful, much of it harmful.

Scavenge, Craft, and Survive




After waking up in your Life Pod, the clock is ticking to find water, food, and to develop the equipment you need to explore. Collect resources from the ocean around you. Craft knives, lights, diving gear and personal water craft. Venture deeper and further form to find rarer resources, allowing you to craft more advanced items.

Construct Underwater Habitats




Build bases on the sea floor. Choose layouts and components, and manage hull-integrity as depth and pressure increase. Use your base to store resources, park vehicles, and replenish oxygen supplies as you explore the vast ocean.

Disrupt the Food Chain




The ocean teems with life: Use the ecosystem to help you. Lure and distract a threatening creature with a fresh fish, or simply swim as fast as you can to avoid gnashing jaws of roaming predators.

Handle the Pressure




Build a Pressure Re-Active Waterproof Nanosuit, or PRAWN Suit, and explore extreme depth and heat. Modify the suit with mining drills, torpedo launchers, propulsion cannons, grappling hooks and more.

Fear the Night




As the sun goes down, the predators come out. The ocean is unforgiving of those caught unawares in the darkness. Areas that are safe to explore during the day become treacherous at night, but also reveal a beauty that those who hide from the darkness will never see.

Go Below The Deep




Cave systems wind below the sea bed, from dark claustrophobic passages to caverns lit by bio-luminescent life. Explore the world below the ocean floor, but watch your oxygen levels, and take care to avoid the threats lurking in the darkness.

Open Development




Get weekly or daily updates, see what the development team is working on, view real time change logs, and give feedback from inside the game. Subnautica Early Access development is open, and the development team wants to hear from you.

About the Development Team




Subnautica is being created by Unknown Worlds, a small studio founded by Charlie Cleveland and Max McGuire that traces its roots back to the 2003 Half-Life mod Natural Selection. The team is scattered around the globe, from the United States to the United Kingdom, France, the Czech Republic, Russia, Thailand, Australia, and many more places. There is a central office in San Francisco, California that serves as home base for the whole team.
