King under the Mountain is a simulation-based settlement-building strategy game set in a fantasy world. You take charge of a group of settlers founding a new colony, planning out work to be done and designing the rooms and structures that make up a burgeoning society. The focus is on having a deep simulation of characters and their behaviour as well as the world and environment they inhabit.
Every map is randomly generated from an initial seed so that no two maps will ever be the same, every tree, plant and character will have their own unique combination of colours and appearance.
You can play as several different races and factions each with their own unique gameplay elements. You could build a dwarven fortress dug deep into the side of a mountain, a town of humans at an important river crossing, or a tribe of orcs hunting and raiding others.
