Lets watch some videos for Diablo III PC

Diablo III picks up the story twenty years after the events of Diablo II. Mephisto, Diablo, and Baal have been defeated, but the Worldstone, which once shielded the inhabitants of the world of Sanctuary from the forces of both Heaven and Hell, has been destroyed, and evil once again stirs in Tristram. Playing as a hero from one of five distinct character classes, players will acquire powerful items, spells, and abilities as they explore new and familiar areas of Sanctuary and battle hordes of demons to safeguard the world from the horrors that have arisen.
