Diablo III is a dark fantasy/horror-themed action game by Blizzard Entertainment, the third installment in the Diablo franchise. The game features elements of the hack and slash, dungeon crawl and action role-playing genres. The game takes place in Sanctuary, the dark fantasy world of the Diablo series, twenty years after the events of Diablo II.
Gameplay is similar to that of previous titles in the Diablo franchise. The game is classified as an action role-playing game that is played primarily using the mouse to direct the character with supplementary commands provided through the keyboard.
As in Diablo II, multiplayer games are possible using Blizzard's Battle.net service, with many of the new features developed for StarCraft II also available in Diablo III. Players will be able to drop in and out of sessions of co-operative play with others. Unlike its predecessor, Diablo III requires players to be connected to the internet constantly due to their DRM policy, even for single-player games.
Diablo III will feature two types of auction houses; one where players spend in-game gold and another where players can buy or sell virtual items for real-world money. The real-money auction house will not be available in Hardcore mode.
There are five available character classes: Witch Doctor, Barbarian, Wizard, Monk and Demon Hunter. In the previous two games, each class had a fixed gender, but in Diablo III players may choose the gender they would like to play.
