Diablo III

Diablo III is an upcoming dark fantasy/horror-themed action role-playing game in development by Blizzard, making it the third installment in the Diablo franchise. The game, which features elements of the hack and slash and dungeon crawl genres, was first announced on June 28, 2008, at the Blizzard Worldwide Invitational in Paris, France^, and is stated for release in North America and Europe on May 15, 2012, and in Latin American countries and Russia on June 7, 2012.

The game takes place in Sanctuary, the dark fantasy world of the Diablo series. This world was saved twenty years prior by a handful of unnamed heroes in Diablo II, heroes who, having survived the onslaught brought by the armies of the Burning Hells, have gone mad from their ordeals. It is up to a new generation of heroes to face the forces of evil threatening the world of Sanctuary.

Players will have the opportunity to explore familiar settings such as Tristram.

The only confirmed NPCs are Deckard Cain, who has appeared in both of the previous games, and his niece, Leah, a new character who accompanies the hero in quests from time to time. The plot will revolve around two surviving Lesser Evils, Azmodan and Belial, and an artifact known as the Black Soulstone.Diablo's world map is composed primarily of two main continents with several small islands in the Northwest region. The world of Sanctuary has been dramatically changed by the events of Diablo II: Lord of Destruction, for the destruction of the World Stone underneath Mount Arreat has reshaped the world's geography.
