League of Legends is a FREE game inspired by the Defense of the Ancients map for Warcraft III: The Frozen Throne developed and published by Riot Games for Microsoft Windows. It was first announced on October 7, 2008 and released on October 27, 2009. The game was in a closed beta from April 10, 2009 to October 22, 2009. It then transitioned to open beta until release.

Steve "Guinsoo" Feak, the previous designer of the popular Warcraft III: The Frozen Throne custom map, DotA Allstars, and Steve "Pendragon” Mescon, the administrator of the former official support base for the map (www.dota-allstars.com), were involved with Riot Games in the development of League Of Legends. Using the original DotA created by Eul (the original Defence of The Ancients map for Warcraft III: Reign of Chaos) as a base, Guinsoo made DotA Allstars by inserting his own mix of content, largely expanding the number of the heroes, and adding recipes, numerous items and various gameplay changes. Guinsoo then passed version 6 of the map on to its current developer, Icefrog. Pendragon, who is the Director of Community Relations for Riot Games, helped create the previous DotA Allstars website along with its forum.
