Patch 1.6.66 Release Notes

Darkest greetings Underlord,

The patch number of the beast marks an auspicious occasion for our fans in a number of countries over on the continent! At long last we’re in a position to update our unsupported but not forgotten European languages, and bring them in line with the English, French, German, and Chinese localisations.

You can read our full announcement post here.


European Languages Return!

As announced in our previous post, and in today’s announcement, we’re proud to reveal that the discontinued European languages are now updated and back in the game, and we’ll be continuing their support into the future! We welcome your feedback!

  • Updated previously deprecated European Languages to include all the game’s text updates since Patch 1.0.1:
    • Spanish
    • Italian
    • Polish
    • Russian
  • Added subtitles in various pre-rendered cinematics throughout the game for the above languages

Gameplay Changes



  • Can no longer pass through Possession Doors

Spirit Worker


  • Can no longer pass through Possession Doors



  • Constructs may no longer be placed inside shrines or Dungeon Cores



  • Now has an effect if used twice on the same defence.


AI Improvements

  • Workers will no longer attack anything except rival Workers, regardless of how high their chances are to win. This is to keep them on task when working near low-threat objects such as doors.

Mutator Changes
