Diluvion 1.2 Beta Is Here (Read before downloading!)

We're excited to announce that the very first beta of Diluvion 1.2 is ready to download!

This version contains the Forgotten Fjords. It's highly recommended that you start a new game. Loading files from the previous version isn't yet supported, however it will be very soon. If you do decide to load a save file from the previous build, be sure to back it up first.

To access, right click on Diluvion, go to Properties -> Betas -> Beta. You should see a download for 1.9GB begin. If it doesn't start, go to Properties -> Local Files ->Verify Integrity of Game Files.

This is our first beta for 1.2, so you likely will run into some bugs. If you want to help out your friendly neighborhood dev, please let us know in the forums if you run into a bug.

  • New language terms aren't yet localized. These will appear in [] brackets, or with [no loc] tags.
  • Gamepad controls aren't fully implemented

Moving Forward
Being the very first beta of 1.2, this is far from the release state. However, we'd love to hear your feedback on the new features. We'll continue releasing beta versions with bug fixes, more content, and balance tweaks. Thanks for being so patient and we hope you have a great time!

If you return to version 1.17 after playing 1.2, there may be an issue where your 1.17 save files don't show up. This can be caused by newer save files confusing the old build. Simply browse to your save files at C:\Users\[USERNAME]\AppData\LocalLow\Arachnid Games\Diluvion\SaveFiles and move any 1.2 save files from this folder to fix the problem.
