深淵號角

深淵號角是一款與末日之刃和死亡陰影同樣等級的非官方擴展包。

深淵號角（Horn of the Abyss）（簡稱HotA）是《英雄無敵III》的一款製作相當全面的非官方擴展包，旨在延續經典的RoE/AB/SoD系列。

該項目的目標是創建一個為《英雄無敵III》增加大量新功能的擴展包，但同時忠於原遊戲的公式和願景。主要關注的是對修改遊戲的每個方面的質量。這包括仔細修復原遊戲的平衡問題，消除開發者遺留的圖形缺陷，並增加大量新內容，如新的戰役、新的地圖物件和新的可玩派系。該項目以原始《魔法門》宇宙為基礎，力求保持與原作的聯繫。

與基於《追隨神跡》的模組不同，深淵號角將新的城鎮直接添加到遊戲中，而不是替換掉任何現有的城鎮。該擴展包需要玩家擁有《死亡陰影》或《英雄無敵III完整版》才能運行。
