Diablo: Hellfire

Diablo: Hellfire is the expansion pack for the video game Diablo, developed by Synergistic Software, a Sierra division, and published by Sierra On-Line in 1997. Despite the objections of Blizzard Entertainment, the Hellfire expansion was produced, permitted by Davidson & Associates, their parent company at the time. Blizzard North, who was developing the sequel Diablo II, thus imposed numerous restrictions upon Synergistic Software's development of Hellfire.
