Maelstrom — HotA 1.3.0+

Maelstrom is a large underground-capable map for six players, each of whom may be human, with no teams and every player free to fight the others. Its 108 by 108 playing field is dominated by rock, with water covering roughly a fifth of the ground and smaller patches of grass and sand. Each side may choose from nine factions, including Cove and Dungeon, and the map plays at the Impossible difficulty setting. Victory requires defeating every enemy, while a player is eliminated once they lose all their towns and heroes. Across the map are 12 towns, 18 heroes, and 150 random artifacts, along with 33 creature banks, 39 monoliths and portals, and scattered Water and Ice Elementals. The author's note stresses shifting fortunes and unstable ground.
