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. https://youtu.be/Afp3HYVXFtA

Heart of Gold features:
