What the developers have to say:

Why Early Access?

“With Tides of Tethys, our goal is to make this game for you!
Even though we have our own vision of the game, having this in the hands of players will allow us to focus on areas that matters the most to you, our players.”

Approximately how long will this game be in Early Access?

“Our current goal is to be in Early Access for aproximately a year, but this will potentially be affected by revenue, as this will affect our scope.

Our main focus during this year will be on biome and gameplay variety as well as balance and polish, but we want to make room to add or tweak things that the community wants to see in the game, whether that's buildings, events, enemies, tools or cosmetics.”

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

“For the full version, we plan to add more variety and locations per biome, more dangers in the world as well as more ways to deal with those dangers, be it with tools for your knights or buildings for your outposts.

We also are planning to add more ways to affect the world in the shape of events, local ( you find an object that gives you a choice and consequence/reward) or global ( Similar to our global tides/ lighting events).”

What is the current state of the Early Access version?

“Currently the Early access version has most core features there :
-Going on an expedition
-Randomized levels and events
-Building outposts
-Harvesting resources
-Finding and equipping gear
-Unlocking new ways to survive (Knight gear, and buildings for your outpost as well as perk cards and "Houses")
-Customizing Knights

The game currently has a fair amount of bugs and the perf varies. Overall we've seen a stable 30-60fps in most places but there are definitely improvements to be made. There can be scenarios when the stars align the wrong way and perf drops but we're hard at work fixing all that.

Balance overall still needs work and both enemies and economy are constantly being tweaked.

Combat is also at a rather early iteration, and definitely needs more depth (pun intended!)

We're planning on having 4 regions, but currently 2 regions are more solved than the others.”

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

“We will potentially raise the price closer to 1.0, and do want to reward early adopters with a more approachable price than what the game will be around 1.0, but we do want to keep the game at a fairly reasonable price point overall (We're not quadruple A, after all).”

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

“We want to hear your thoughts!
We're making this game for you, our community, and Tides of Tethys is the perfect platform to add new mechanics, fun gear and ways to play.

We put a lot of work into our foundational systems just so that we could build the rest with the community in mind.

We'll be reading forums, and will have a discord server where we'll actively listen to all your feedback and suggestions.”

About This Game

Tides of Tethys is an immersive underwater roguelite simulation game centered around exploring and surviving the uncharted depths of an alien world, while building and maintaining modular outposts.

Players will lead expeditions of Knights into the unknown, in the hopes of rebuilding their long lost kingdom and unifying the houses of Tethys once again.

As they dive further into the Abyss, they will discover compelling new places, uncover lost technologies, and conquer a variety of dangers that lurk beneath the surface.

Features :

  • Explore an ever changing procedural world, where no two expeditions are the same, and delve deeper into the uncharted trenches of the Abyss
  • Build modular outposts, and transport parts of it with in your Mothership to help you survive the challenges of the deep
  • Discover ancient Relics to uncover lost technology for your outposts as well as tools and vehicles for your Knights
  • During each expedition, choose between meaningful perks to help you survive the trenches
  • Rebuild your Kingdom to its former glory! With each victorious expedition, unlock more perks, tools, factions and customizations
  • Whether it's conditions like darkness, changing current speeds or simply running into events that require you to make snap decisions... What will you do, faced against the unknown?


    The world of Tethys is a dangerous and diverse one.
    With each expedition comes new locations to discover, and with each depth, new challenges to overcome!


    As an expedition leader, you will lead your trusted Knights to explore and retrieve long-lost Relics from the ancient wars that divided the Houses of Tethys..
    Retrieving Relics will allow you to retrofit that technology on your outposts, as well as your Knights and let you adapt to the ever growing challenges of the deep!


    With each conquest and failure comes knowledge and rewards!
    Will you unlock more ways to navigate the tides, upgrade your mothership to carry over more of your outpost each depth, or maybe try out a run with a newly unlocked House, offering its own set of advantages and challenges?
