This product can ONLY be activated on the GOG platform.
This bundle includes the following:
Originally developed by Synergistic Software and released in 1997, Hellfire was not an official Blizzard product and did not carry Blizzard’s endorsement or label. Despite that, in response to Diablo players who have expressed a desire to experience the content, Blizzard has given the OK for it to be included as a free add-on with Diablo purchases on GOG.COM.
Hellfire offers a non-canonical single-player storyline where players must defeat a powerful demon named Na-Krul who is threatening Tristram. The expansion also adds a Monk class, new weapons and items, new missions, locations, dungeons, and enemies. Hellfire will be accessible while launching the original Diablo.
Traveler, stay awhile and listen...
Darkness stirs beneath Tristram. An ancient evil sweeps across the land, plunging it into civil war and terrorizing the populace. A mad king, his missing son, and a mysterious archbishop are all pieces of the puzzle you need to hack through. You have journeyed to the source of this evil. The town of Tristram - now inhabited only by a handful of survivors, broken and twisted by the madness that has befallen them. A cathedral stands there, built over the ruins of an ancient monastery. Eerie lights and ungodly sounds are heard echoing through its abandoned halls, and that is where you shall venture.
Embark, if you dare, on a quest to destroy The Prime Evil…
