Diablo 1 HD Mod (Belzebub) is a fan‑made enhancement and overhaul of the classic Diablo (1996) action RPG, specifically designed to modernize the original Diablo I experience on Windows. Unlike the untouched retro game, Belzebub updates graphics, interface, and gameplay while preserving the dark atmosphere that made the original beloved. This unofficial mod, often referred to by its project codename Belzebub, adds high‑resolution support, widescreen compatibility, restored and expanded quests, new classes, and features that bring the game closer in depth to Diablo II, all while keeping single‑player focus.
Belzebub introduces redesigned menus and UI elements, expanded itemization with sets and crafting, rebalanced monsters and bosses, and more role‑playing depth through unique class skills. The mod is in open beta and has been widely shared on modding communities and platforms like GOG as a convenient one‑click install. To play, users need a copy of the original Diablo 1 game files, after which the mod overlays the classic experience with modern conveniences and considerable added content.
