New World, New Adventure

A new world awaits alongside an all-new story. You are a pioneer traveling to a distant world, but something is amiss. The ship's AI insists you carry on the mission. This world is too dangerous for humans to survive… Unless you change what it means to be human. What creatures, intelligent or otherwise, await your arrival?

Explore with Friends

Play alone or with up to three friends in online multiplayer co-op. Whether exploring mysterious ruins, building custom bases, or adventuring deeper into the world… The challenge of this planet will test your ingenuity and ability to adapt, in unexpected and curious ways.

Craft Submersibles, Tools, and Bases

Survival depends on utilizing the right tools. Alongside basic items such as your Scanner and Flashlight, you’ll find recipes for more advanced tools, equipment, and submersibles. Bases are more customizable with an overhauled building system. New tools allow for greater adaptation to the world.

Uncover Diverse New Biomes

From towering underwater cliffs to lush coral fields, this aquatic alien world is brimming with vibrant and breathtaking biomes, each teeming with diverse ecosystems and unique creatures.
