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...

Diablo 1.5, bigger and better

I've been playing this mod for a few years and I must say, is quite hard going back to vanilla Diablo 1 after playing it. It's the same old classic we all know, just with "more". More sidequests, more items, more classes, more content. Item sets and magical properties and even new equipement types are backported from Diablo 2, Item management is improved thanks to a personal chest, and a shareable one among all characters in your PC. Classes now have a few unique skills without being full blown skill trees, and new spells with requisites other than Magic are also available, giving much needed variation. One of the more interesting additions is the restoration of certain sidequests and lore elements initially cut from the game, like the originally planned appearance (and fate) of Izual or the Map of Stars that force you to battle Diablo within 30 minutes, or he'll be massively buffed. If you love both Diablo 1 and 2, you should give this mod a try. Hey, it's free!

The best way to play vanilla D1.

It's the most fleshed-out vanilla D you could ask for, with lots of polish, bug squishes and restored content. (That Butcher cutscene!) If you want a remastered, faithful single-player HD upgrade to celebrate the nearly 30-year legacy of Blizzard North's classic, then look no further... Belzebub is the one. For multiplayer, you can check out Noktis's website for the latest update of the fork. It's called Tchernobog. Works really well! Good stuff. But if you're a true D1 vet' seeking the most robust and challenging mod of all, TH Team's long-running fan project The Hell will make your hairs stand on end. It's wild! (The latest finished one, III, is a free download on their Patreon page, with IV in pre-alpha.) With these mods, D1 bros be eatin' good for years to come!

Brilliant!

Only at dungeon level 3 so far, playing as necromancer, but so far a great experience. This mod takes the original Diablo and makes and closes the gap between between the original Diablo and Diablo II! Graphics and zoom out view are great. Fantastic mod!

Awesome, for a certain type of player

My reason for writing this review is to try and let players know what they're getting into before investing hours of gameplay and, potentially, hitting a wall like I did. I did play Diablo back in the day as well as Diablo 2. I have now played Belzebub with two different character classes (assassin, necromancer) to the final level on Normal difficulty. I, too, felt like I was playing 'Diablo 1.5'. Belzebub incorporates many of D2's gameplay elements and changes into D1. It brings many, many new / restored features and I couldn't possibly go into detail on all of them. From what I've seen most of them work very well. The creators of this mod deserve a ton of respect. There is one signifant change in particular that I will mention here because it was one my reasons to eventually stop playing, and it's imho not obvious from most feature lists. With Belzebub, levels are randomly generated each time you load a game. After loading, you always start in Tristram. There are 'waypoints' on every two levels that you have to manually reach and activate to be able to later return to that level. This is very much like D2 handled it. This change alone had massive implications for how I'd play the game. Fully exploring a level can very easily take more than an hour, and much more if you want to complete sidequests along the way. I think it is fair to say that to play Belzebub in any meaningful way, you have to have a lot more time at your disposal than what was necessary for the original D1. For example, you could play vanilla D1 for half an hour, save the game somewhere midway through level 9 and continue right there tomorrow. With Belzebub, you'd reload back in Tristram and would have to teleport to the waypoint on level 8, which is now completely reset and randomized so you may have to play through it all over again just to get back to level 9, which is now also completely reset and randomized again. Often I found myself trying to beeline for the next waypoint to activate just so I could stop playing for the day without having made no progress. What killed it for me in the end, though, was a sudden, massive spike in difficulty upon getting to the final level ('Terror Domain') on Normal difficulty. I encountered this with both characters. Up to that point, both characters were doing rather well and capable of defeating all mobs and bosses without the game feeling too easy. There are several bosses on Terror Domain, and both my characters were suddenly hopelessly outmatched against the first and the second boss, respectively. In other words, yes, I haven't even encountered Diablo yet. I had to use weird tactics involving the Teleport and Town Portal spells to beat that one boss, so it didn't even feel challenging or rewarding, just plain silly. And yes, I did try different spells, items, what have you. I'm sure with a lot of grinding both characters could eventually beat those bosses and Normal difficulty. But man do I have better things to do with my life! So here is my conclusion. If you can live with (or even like) the map reset every time you reload a character, Belzebub is probably going to be a lot of fun for anyone who enjoyed D1 and D2, up to the final level on Normal difficulty. From that point on, however, Belzebub seems sharply geared towards hardcore players with a lot of spare time on their hands and a willingness to grind up their characters' XP and items.

Nice!!!

I haven't played much of this mod yet but at face value it is pretty slick! It would appear to be a huge win for Diablo 1 fans. I will say though, PLEASE add an option to turn off the floating hit/experience numbers. I hate having my screen fill up with numbers. As well, if a movement speed increase is possible for when players are in Tristram than that would be a nice addition. I'm not saying to rework the whole game to increase player speed... just that walking around the town has gotten old... esspically for those who have been playing this game since the 90's.
