League of Legends is a session-based, multiplayer online battle-arena game where rival teams compete against one another for victory on highly stylized battlefields and landscapes. Built by a veteran development team and the original creators of Defense of the Ancients (one of the world's most popular player-made mods), League of Legends combines elements of the role-playing and strategy genres with addictive battle action. League of Legends brings accessible, replayable and endlessly competitive gameplay that deepens with the player's commitment.
