Dota (Art of War)

Dota stands for Defense of the Ancients. Dota is not game itself; it is a multiplayer map on Warcraft III: The Frozen Throne. But because of its fame and ample differences with the rest of the game, this map is often considered an entirely separate game itself rather than just a map in The Frozen Throne.

The scenario was developed with the "World Editor" of Warcraft III: Reign of Chaos, and was updated upon the release of the expansion, The Frozen Throne. There have been many variations of the original concept; the most popular is DotA Allstars, which has been maintained by several authors during development. The current developer is known by his pseudonym as "IceFrog", and has been developing the game since 2005.

Since its release, Allstars has become a feature at several worldwide tournaments, including Blizzard Entertainment's BlizzCon and the Asian World Cyber Games, as well as the Cyberathlete Amateur and CyberEvolution leagues; Gamasutra declared that DotA was perhaps the most popular "free, non-supported game mod in the world".

Because the gameplay revolves around strengthening individual heroes, it does not require one to focus on resource management and base-building, as in most traditional real-time strategy games. Killing computer-controlled or neutral units earns the player experience points; when enough experience is accumulated, the player gains a level. Leveling up improves the hero's toughness and the damage it can inflict, and allows players to upgrade their spells or skills. In addition to accumulating experience, players also manage a single resource: gold. The typical resource gathering of Warcraft III is replaced by a combat-oriented money system; in addition to a small periodic income, heroes earn gold by killing hostile units, base structures, and enemy heroes.This gives rise to a technique called last hitting, which is when the player attacks a hostile unit when "its hit points are low enough to kill it with one blow". Using gold, players buy items to strengthen their hero and gain abilities. Certain items can be combined with recipes to create more powerful items. Buying items that suit one's hero is an important tactical element of the scenario.



Allstars offers a variety of game modes, selected by the game host at the beginning of the match. The game modes dictate the difficulty of the scenario, as well as whether people can choose their hero or are assigned one randomly. Many game modes can be combined (for example, an easy difficulty level and a random hero pick), allowing more flexible options.
