Description

The mod is fully playable in English. For other supported languages, localization is partial: while all UI elements remain in English, lore documents and quest content are translated.




Belzebub, or Diablo I HD Mod, is a complex modification for the first installment of the Diablo series, which introduces a number of interesting improvements to the gameplay, a lot of new content and - most importantly - increased resolution.



Belzebub enriches the cult Diablo series with a real mass of intriguing content, presenting it all in HD resolution. The modification adds new locations, missions, spells, skills and monsters, 204 unique items, 170 crafting recipes, several new character classes (Warrior, Sorcerer, Rogue, Necromancer or Barbarian), 28 sets and 105 set items, four difficulty levels available in the single player mode, as well as a host of other gameplay improvements. The developer has also thought of a few additions in terms of interface, support for widescreen, and - as we have already mentioned - full integration with the new Windows systems. There is no denying that there is a lot to it, so every fan of the series, especially of the ‘one’, will undoubtedly not pass by this modification indifferently.

Features:

  • Increased resolution and support for panoramic screens
  • Fully integrated with new windows systems
  • Many user interface improvements
  • New hero classes
  • All quests which were missing from original game are now implemented
  • Four difficulty levels available in single player
  • New locations
  • New special and randomly generated bosses
  • New spells
  • New character skills
  • New item types and affixes
  • 204 unique items
  • 28 sets with 105 set items
  • 170 crafting recipes
  • Great number of minor gameplay changes
  • And many more...

Fantastic Right Up Until The End

A very cool mod which adds various improvements (a lot of them from Diablo 2), more items, more spells, more classes, and, best of all, restores pretty much every quest that was cut out of the original, complete with the voice acting that was recorded for them but never used. I'd always heard that Diablo had a lot of cut content, but I never realized that practically half of the game was missing. The added quests do kind of ruin the pacing of the original story a bit, but I've played the original and am fine with a longer, more difficult and intense quest. As a fan of vanilla Diablo it's really cool even from a historical gaming perspective to see all this stuff in a reasonable facsimile of how it would have originally been presented. One nice thing was the drop rate being altered so you'll see unique items fairly regularly (maybe one every couple play sessions) instead of MAYBE seeing one per entire playthrough of the game. The unique items aren't always very powerful and never were game-breakers, so it's nice to be able to get more of them and build a collection with the new, huge stash system- no more throwing stuff on the ground! You can also share stuff between your single player characters so if you find a unique that's clearly for a different class, you actually have a chance to use it. The new spells were fun, though some of them are still fairly useless, and the addition of rare items like in Diablo 2, as well as a crafting system, are welcome changes. My only complaint so far is that the final battle against Diablo is ludicrous- and I didn't run out of time on the Map of the Stars quest that's been added, which would apparently make him even more powerful. I chose the new necromancer class, and the instant Diablo appears all my summoned skeletons vanish- he doesn't even kill them, they just disappear and he runs right up in my face. Left with no defenses or way to distract him, all I can do is spam lightning bolts at him and drink potions as fast as possible, and it's impossible to keep up- I don't even run out of potions, he slaughters me faster than I can drink them, and this is a class whose main stat is vitality and who spent a lot of time finding or crafting decent gear. I was able to get through everything else in the game, but Diablo is pretty much impossible and unfair. I already went through all the levels a couple more times to build experience, power up my spells and improve my gear- I shouldn't be forced to replay everything before the final boss 18 times in a row just to stand a chance of beating him. Aside from that, the mod is fun and it's amazing seeing all those missing quests restored to their full glory. It makes for a very different, much more grueling and involved experience, but the other new things that have been added keep it from getting dull or repetitive too quickly. It would have been nice to also include everything from Hellfire to truly make this the definitively complete Diablo experience, but as it stands it's an amazing mod and the creators of it are to be commended for all their hard work.

Feels just right

This is more of a restored content mod than a rework as it really nails the mood and feel of original Diablo while subtly adding in enhancements. The Warmth suffix on gear that functions just as it does in Diablo 2 by slowly regenerating mana feels perfectly balanced. It is amazing just how well this game still holds up nearly 3 decades on, it was so substantially ahead of its time.
