Exonautis is an underwater sci-fi survival game set on an oceanic exoplanet. Dropped into a vast alien open world with nothing but your drop pod and a few supplies to get you started, you have to quickly adapt to this biodiverse alien world to make it out alive.

Explore an Expansive Alien Ocean

Planet Eo-III is home to many biodiverse ecological systems brimming with vibrant fish but also dangerous predators. Every biome in Sector Alpha is different, from lush and sunny coral reefs, to deep and dark ravines and caverns, you need to learn about how each zone works in order to survive and dive deeper.

Survive, Explore and Upgrade

After arriving on Eo-III, you will need to find water, food, yourself warm and most importantly, manage your oxygen. Scavenge the ocean floor for resources, craft supplies and tools such as a scanner, sampler and gun. Upgrade your equipment in order to explore deeper, more dangerous areas.

Uncover the Mysteries of Eo-III

Your name is Melody, and you are a convict sent on Planet Eo-III. If you wish for your sentence to be lifted and be rescued from the planet, you need to first uncover what happened to Atteros, a mining expedition group that suddenly vanished 10 years ago in Sector Alpha, but you soon discover that there is more beneath the surface than originally thought, and that some otherworldly alien species might be involved.

However, Atteros is not the only thing you are looking for. Your crew has also been exiled to this planet, and you need to find them. Luckily, they have left behind a droid named Neon. Repair it and he will become your trusted companion and will be pivotal in your survival and finding the answers that you seek.

Pilot Advanced Vehicles

As you venture further into the ocean and away from the protection of the drop pod, you will need to construct various vehicles to help you travel the ocean expanse and dive to deeper depths. Pilot the Horizon Racer, an agile hoverbike that allows you to traverse both ocean and land at vast speeds, or the Neptune Explorer, a one man submersible that vastly increases your underwater exploration capabilities, and upgrade them to further push the boundaries of your exploration.

Construct Underwater Bases

Surviving on an alien planet is not easy and you will soon need to construct your own base. Luckily, the builder tools allow you to easily do that. Choose different layout modules and components and design your custom habitat, a safe point where you can store and replenish your supplies. Inside your base, you can build various farming modules to grow your own crops and build a self-sustaining system, greatly increasing your survival capacity.

Face the Depths

Slowly you will start to make your way deeper and deeper into the ocean. The shallow, sun drenched starting areas will give way to vast underwater plateaus, and deep descents into the lower plateaus, more than a thousand meters below the surface. As you traverse these vast dark oceanic expanses, you will encounter a seemingly bottomless trench filled with horrors but also the answers that you seek. Will you brave the dark depths and uncover the secrets of the planet?
