Hellfire is a single-player expansion to Diablo. It was released digitally by Blizzard Entertainment on Jas a free add-on with every purchase of the original Diablo on GOG.com.

Despite Blizzard Entertainment's objections, the game was produced without their blessing, due to Davidson & Associates, their parent company at the time. Hellfire was re-released alongside Diablo in 1998 in a bundle called 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.
