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.
Diablo II’s storyline progresses through four chapters or “Acts”.
Each act follows a predetermined path, but the wilderness areas and dungeons between key cities are randomly generated.
The player progresses through the story by completing a series of quests within each act, while there are also optional side dungeons for extra monsters and experience.
