Game Description
System Requirements
Activation Details
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...
Heart of Gold continues where the story left off, with four earth-shattering new Campaign levels, a smattering of new defences, units and spells, and a gleaming new Dungeon Theme!
Features
An expanded story told across four 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 players.
An additional four Aspects to master: Sentinel (defence), Gild (spell), Aureate Monolith (construct), and a golden Titan - the Colossus.
A new Dungeon Theme for Kasita, which includes a Dungeon Core, new tiles and walls, a Worker skin, and a much-requested custom Hand of Evil.
New terrain, system overhauls, Map Editor features and much more!
