RiotGames' first release: League of Legends

Join forces with your closest allies as you unite to defeat your foes in deadly multiplayer battle arenas. League of Legends combines elements from both strategy and role playing games to bring you a unique and dynamic player experience. As a Summoner, you will have your own distinct, customizable avatar that grows in power as you move through the game. In each battle you will select and call forth one of dozens of Champions to control and engage in head-to-head combat against teams of highly trained warriors. Choose your allies wisely, for the stakes are high. In the League, every battle means more than life or death as the balance of power shifts with each victory or defeat. [Riot Games]

A new founded developing team (including famous persons like Steve "Guinsoo" Feak, Steve "Pendragon" Mescon Tom "Zileas" Cadwell and many more) and their first game, free to play !
