Diablo: Hellfire is an expansion to the original 1996 game Diablo, released in 1997, a year later, for PC. It has several new features and updates, as well as new elements and a story line of its own. It is a single-player game.
Diablo: Hellfire’s story takes part in the same world and setting as the previous game, except this time players must assume the role of completely new characters and fight new enemies to defeat a new foe. It’s storyline synopsis is that a sorcerer while performing a magical ritual releases a demon by the name of Na-Kurl unto the town of Tristam (also featured in the original game), by mistake, but before it can escape out into the world, the sorcerer is successful in sealing the doors by magic. It is now up to the player to wander into the lair Na-Krul has formed for himself, defeating his minions, learning more about him and his connection with Diablo, and ultimately facing him to vanquish him once and for all.
In the Hellfire expansion, a new class besides the ones already seen (Warrior, Rogue, and Sorcerer), has been added called Monk. The expansion also has new dungeon settings and more quests to take on than were available in the previous games. Several new elements like a whole new list of new spells to learn, oil mechanics that affect the efficiency of the weapons and items, new shrines and mini-bosses have been added. These all elements add to the feel that Hellfire is a completely new game on its own, based on the amount of gameplay value offered here.
While Hellfire masterfully integrates into the original Diablo, it’s levels are designed in such a way that the dungeons that are completely necessary in the original game can be avoided. However, there have also been added dungeons and shrines exclusive to the expansion, where new mini-bosses have been added.
Despite Hellfire being playable on its own, it requires some knowledge and experience from the main game to be played in a truly engaging fashion. The beginning levels of the expansion themselves are at the level of difficulty found in the later levels of the original game, meaning that the difficulty is high, and that players will learn about how the world and the items in it work, as well as experience in dealing with various types of enemies and their traits.
A multiplayer feature to the game is not available. However, the game does feature some multiplayer elements. Two sequels to the main game, Diablo II and Diablo II were released in 2003 and 2011 respectively.
