Defense of the Ancients (DotA) is an action
real-time strategy mod for the video game Warcraft III: Reign of Chaos and its expansion, Warcraft III: The Frozen Throne, based on the "Aeon of Strife" map for StarCraft. The objective of the scenario is for each team to destroy the opponents' Ancients, heavily guarded structures at opposing corners of the map. Players use powerful units known as heroes, and are assisted by allied heroes and AI-controlled fighters. As in role-playing games, players level up their heroes and use gold to buy equipment during the mission.
Since its original release, DotA has become a feature at several worldwide tournaments as well as the Cyberathlete Amateur and CyberEvolution leagues; in a 2008 article of video game industry website gamasutra, the article's author claimed that "DotA is likely the most popular and most-discussed free, non-supported game mod in the world". Valve corporation is currently developing a stand-alone sequel.
