Release Date Change and First Access

Hey DoE fans!

We've released an update to our First Access and added 100 more available keys! Read more on our DevLog:

Second, we are happy to announce we received the Best Design award at SIEGE last weekend!

Third, hopefully this is not too much of a shock, but we've decided to move our planned release date from early November to February of next year. There were several reasons for this but the main one is the lack of visibility we would have by releasing in a prime AAA launch window and competing with the Steam winter sale. We'll also be able to achieve even more of our vision for the final game and ensure that the quality is there for launch.

About This Game


A cataclysmic event has forced humanity to build undersea environments to survive. Now 500 years have passed and we are in decline. Pirates, raiders, androids and worse things scour what is left of these habitats looking to survive. You are part of the Republic - the last members of an unknown country that are dedicated to keeping order. Take on missions, hire mercenaries, navigate the flooded post apocalyptic world and fight enemy factions in turn-based tactical battles that take place in procedurally generated environments.



  • Turn based, tactical control of a squad of mercenaries
  • Randomly generated maps with random encounters
  • Procedurally generated undersea habitats to explore
  • Unlock more starting options with each successful mission
  • Tons of weapons, armor and items to find
  • Many character skills to unlock based on stats and chosen class
  • Recruit unique characters to your team
  • Perma-Death!
  • 15+ different enemy types, each with unique AI and attack patterns
  • Beautiful pixel art environments where everything is destructible


Strongly influenced by games such as FTL, X-Com (originals and reboots), Fallout 1 & 2, Shadowrun Returns (plus sequels) and Wasteland 2, this tactical rogue-like RPG stands on its own as a worthy game for fans of those series.
