"Two decades have passed since the demonic denizens, Diablo, Mephisto, and Baal, wandered the world of Sanctuary in a vicious rampage to shackle humanity into unholy slavery. Yet for those who battled the Prime Evils directly, the memory fades slowly and the wounds of the soul still burn.
When Deckard Cain returns to the ruins of Tristram's Cathedral seeking clues to new stirrings of evil, a comet from the heavens strikes the very ground where Diablo once entered the world. The comet carries a dark omen in its fiery being and it calls the heroes of Sanctuary to defend the mortal world against the rising powers of the Burning Hells - and even the failing luminaries of the High Heavens itself."
The game takes place on Sanctuary, a world of dark fantasy. Unbeknownst to most of its inhabitants, Sanctuary was saved some twenty years ago from the demonic forces of the underworld by a few brave and powerful heroes. Most of those warriors who directly faced the armies of the Burning Hells -- and were fortunate enough to survive -- went mad from their experiences. And most of the others have buried their haunted memories and pushed the horrors from their thoughts. In Diablo III, players will return to Sanctuary to confront evil in its many forms once again.
Diablo III will be a fitting sequel to Diablo II, with the easy interface, fast-paced action, and visceral gameplay that Diablo players have come to expect and enjoy. It will also include many new features that will take the Diablo action-RPG experience to the next level. We look forward to going into much more detail on our plans for Diablo III as development on the game progresses.
