Set shortly after the events of Diablo, the player controls a new hero, attempting to stop the destruction unleashed by Diablo's return. The game was developed over a three-year period, with a crunch time of a year and a half.

The producers were Matthew Householder and Bill Roper. The game, with its dark fantasy and horror themes, was conceptualized and designed by David Brevik and Erich Schaefer, who, with Max Schaefer, acted as project leads on the game. Diablo II is an action role-playing hack-and-slash video game developed by Blizzard North and published by Blizzard Entertainment in 2000 for Microsoft Windows, Classic Mac OS, and macOS.
