Obrona — HotA 1.7.1+

Obrona is a small underground map for Horn of the Abyss, designed by Atarosek and rated hard. Its 36 by 36 tiles are mostly rock, lava, grass and dirt, with no water. Three players share the field: Red plays Rampart, while the computer-controlled Blue and Tan play Inferno with Necropolis and Dungeon respectively, and only one human player may take part. There are no teams. The goal is to defeat all enemies, and the game is lost if a specific town falls. Seven towns and ten heroes are placed across the level, along with thirteen mines. Wandering monsters include Cerberus, Vampire Lords and Centaur Captains, and the map contains a few artifacts such as the Sword of Hellfire and the Crown of the Five Seas. Four monoliths and portals and three timed events add to the pressure.
