First Expansion: Heart of Gold Announced!

Wordpress Header HoG


Update: Heart of gold will be releasing in May 2016 due to delays announced in this post

Darkest greetings Underlord,

The Emperor is gone and the Empire rudderless, the balance of power easily swayed to any Underlord that is not 600 feet under. You will now assume the role of rival Underlord, Kasita, and with the mentorship of the deliciously sardonic Mendechaus (voiced by Richard Ridings), you will sate your thirst for wealth and power in the golden and volcanic dukedom of Phaestus.

The word in the Underworld is that Kasita’s heart is a giant gemstone, hewn from the dirt by her prospecting workers. They say molten gold flows through her cavernous, subterranean arteries, and that soon her temper shall erupt in an all-consuming gold rush of greed! Miserly miners beware …

War for the Overworld’s first expansion, Heart of Gold, continues where the story left off, with 4 earth-shattering new Campaign levels, a smattering of new defences, units and spells, and a gleaming new Dungeon Theme! This builds upon the 39 free patches that have massively improved the game since launch, including the recently released patch 1.3 with a map editor and Steam Workshop support.

Heart of Gold features:

  • An expanded story told across 4 brand new, fully voice acted Campaign levels, this time played from the perspective of Underlord Kasita. The levels are more open-ended than in the original game, directly addressing feedback from our most loyal Underlords.
  • An additional 4 Aspects to master:Sentinel (Defence), Gild (Spell), Aureate Monolith (Construct), and a golden Titan – the Colossus. More details to be revealed soon.
  • A new Dungeon Theme for Kasita, which includes a Dungeon Core, new tiles and walls, a Worker skin, and a much-requested custom Underlord hand.
  • New terrain, system overhauls, Map Editor features and much more!

Priced at just £5.59 / $7.99 / 7.99€, the Heart of Gold expansion will be released on Steam in April 2016.

Heart of Gold also constitutes the Early Adopter Bonus for those that purchased War for the Overworld on or before May 2nd, 2015 (which includes Kickstarter backers, Early Access customers, and owners of the physical Underlord Edition). These Underlords will be able to download Heart of Gold from Steam for free when it launches.

This expansion is the next in a long line of updates that have added heaps of new content and fixes since launch.

  1. EEEPPPIICCCC!!!, Can’t wait!

  2. […] you would like to read more about the Heart of Gold expansion, please visit for more […]

  3. Very nice, the ride goes on 🙂

  4. U are F@#ing AWESOME TEAM. Patche`s, updates, new ideas and expansion. It was my best invested money.

  5. Great to hear you guys are as excited as we are 🙂

  6. I’m playing WFTO since it’s launched. The game went a long way and now, after many patches is really great! I’m enjoying the custom maps from steam workshop and I will gladly buy the dlc when it comes out. Still, please work on adding custom events, triggering some actions etc. in map editor. If you manage to do that, I am sure the game will last for many years, and the community will work on great maps. Please consider it, regards and best Easter wishes from Poland!

  7. Awesome 😀

  8. Very cool 🙂

  9. Stop wasting time on expansions and start working on performance.

    • One of the patch notes says “Significant performance improvements”.
      So let’s see 😉

    • Why not both? 😉

  10. A bit disappointed actually. Playing the level where I am up against numerous noisy rival dungeon keepers.

    So far in nearly a dozen levels I have only had the chance to build a proper dungeon once. The original games were much fun.

    A shame really. I am quite the fan of DK..

    • Among the feedback we’re looking to address with Heart of Gold levels is the pacing. Hopefully you should find you have much more time to construct your dungeon in these levels. 🙂

  11. will buy 🙂

  12. I love the evil voice of Richard Ridings

  13. I’m loving the game just like the good old DK days. Looking forward to the expansion pack!

  14. Does anyone know the exact date for release in April?? My hands are getting twitchy…. 😀
