Interregnum — HotA 1.7.2+

Interregnum is a small underground map for Horn of the Abyss, measuring 36 by 36 tiles and set on a single subterranean level. Four players can take part, with up to three controlled by humans and Green reserved for the computer, which plays a Dungeon faction. Red, Blue and Tan begin with random factions, and there are no teams. Victory requires defeating all enemies, while a player loses once all towns and heroes are gone. The terrain is dominated by rock, with highlands, grass and subterranean ground making up the rest. The map scatters 59 random monster stacks, 18 random artifacts, six mines and twenty monoliths and portals. Dwellings for troglodytes, harpies, medusas, minotaurs, manticores and red dragons add further challenge.
