Diluvion Beta: June Update

Hey there! It's been quite some time since our last announcement. We have a new update to the beta, and this is a big one!

The beta's main quest line is now complete from start to finish.

We've fleshed out the Abyssal Trench quite a bit, and there's a lot of new stuff to see there.

Check out our update video here

We'd also like your input on what the full title should be: Right now it's between Diluvion: Accretion and Diluvion: Sunken Grimoire. Let us know in the comments!

  • Completed quest chain in Sunken Coast
  • Completed quest chain in Abyssal Trench
  • Items can be used in hazard battles while salvaging
  • Completely revised quest update HUD
  • Added 'Crew Overview', 'Sub Overview' panels to Captain's Tools
  • Fixed Sonar bug where signals were never decaying
  • Fixed bug where AI would use player's ammo
  • Crew Exchange - crew can be placed on standby when swapping to a smaller ship
  • Fixed numerous small UI bugs
  • Revised munition effects
  • New scenes for forging an upgrade, swapping ships, upgrading chassis

What's Next
First on our todo list is to complete the script for the few remaining side quests so that we can begin full localization. While that's happening, we'll be working on gamepad implementation and general polish.

Thanks for reading, and we hope you enjoy the latest build. :)

1.2 Beta Updated with Save-Anywhere Feature

To all our players, thank you for sticking with us through this journey, and having patience with bugs and imbalance in the beta build. Your feedback not only helps us identify issues, but motivates us along the way.

To new players: there are effectively two versions of the game available. By default, you'll get the stable launch version. We identified some mechanics and features we want to change post-launch, so we created a newer version with the working title of 'Diluvion 1.2' (yes we're coming up with a better name). The new version is still in beta, but it's available to you if you're interested in being involved in the development process.

We've updated the beta with a much requested feature - as long as your sub isn't in immediate danger, you can save anywhere! We still have the 'save fish', which behave more like an autosave.

Full Changeset (1.2)
  • Added option to save in pause menu
  • Added option to load file in pause menu
  • Reworked 'load file' panel
  • Fixed bug where speed would increase indefinitely when changing helm station's crew
  • Fixed soft freeze when quitting to menu
  • Added confirmation panel when quitting to menu or desktop
  • Fixed bug where camera would lock when swapping ships
  • Lots of small hazard balance tweaks
  • Balanced loot values in Sunken Coast

Known Issues (1.2)
  • Torpedo targeting UI can be buggy
  • DLC ships will appear as an empty chassis - do not switch to this empty one
  • Some issues with the Lich hazards
