Diablo 1 in First-Person View : A Solo Modder Resurrects Tristram's Hell

"Fresh Meat !" : The Butcher of Tristram now awaits you face to face

Modder Drelvak is accomplishing what generations of players have dreamed of without ever daring to imagine it : running the original 1996-1997 Diablo entirely in first-person view. What makes the concept so compelling is that this is neither a remake nor an approximate remaster. We are looking at a true reinterpretation : the actual game, featuring authentic code and original vanilla balancing, simply experienced from the inside. And on top of that, development is moving fast.

The Old Dungeon, Experienced from Within

DevilutionX as a foundation, personal vision as the engine

I can still hear the phrase perfectly, and you probably can too if you are around forty : "Fresh meat !". This time around, the Butcher will not greet you from an isometric overhead angle, but right in front of you, at eye level, inside a corridor of the Tristram cathedral. This is precisely what Drelvak delivers, an experienced modder who undertook the challenge of converting the entirety of the original Diablo into first-person.

His mod runs the original game code, complete with procedural dungeon generation, combat calculations, and authentic vanilla balancing. A simple press of the G key instantly toggles between the 1996 isometric view and the subjective view, confirming it is indeed the exact same game, running in the same match, at the exact same moment. I loved having that camera-switching feature in Blizzard's Diablo II remaster, and seeing that exact idea brought to life here by a solo modder is genuinely breathtaking. Video proof already exists : we fight the Butcher in subjective view, cathedral levels are fully mapped, catacombs unfold before our eyes, and the town of Tristram takes shape.

The technical foundation builds upon DevilutionX, the open-source source port of Diablo and its Hellfire expansion, which Drelvak heavily modified and enriched with 3D features. This is where the project becomes fascinating : Diablo consists entirely of 2D sprites and bitmap images. No 3D models, no structural geometry. Drelvak initially attempted the absolute taboo : projecting and stretching original sprites without adding any geometry to preserve maximum fidelity. The experiment failed repeatedly, resulting in shattered visuals. He then accepted introducing minimal geometry, following principles reminiscent of Wolfenstein 3D or Doom, providing just enough volume to stretch the original textures across surfaces. Result : zero generated artwork, zero detailed models, with 1996 textures mapped onto the simplest possible shapes. The aesthetic truly evokes classic Doom, and the kinship is no accident : both games originally relied on 2D sprites, where a simple perspective shift bridges their visual aesthetics.

What Changes... To Keep Everything the Same

Adaptations in the service of absolute fidelity

Converting an isometric view into a subjective perspective required thoughtful adjustments, which Drelvak embraces fully. Visual combat feedback, originally conveyed through isometric animations, required compensation : slash effects on attacks, a crosshair turning red when a target is in range, and impact hit markers. Dropped loot now displays floating labels permanently and is collected with a press of E. The Rogue's bow functions reliably where arrows serve as a purely visual approximation, yet the underlying shooting logic remains rigorously faithful to the original.

However, movement remains grid-based. Diablo operates on discrete tiles, and in subjective view, players still advance step by step, reminiscent of Legend of Grimrock. This design choice is not a flaw but a deliberate statement of fidelity : that remains how the 1996 game plays. The modder mentions exploring possible interpolation to smooth out the sensation without ever altering the underlying system.

Tristram, the Masterpiece of Design

The same philosophy applies to Tristram, the technical showpiece of the project. Rather than rebuilding the town from scratch, Drelvak scrutinized every single tile of the original artwork, every building, every tree, and every rock to deduce precise volumes. When community members pointed out missing elements (glow from Griswold's forge, cathedral red halos, undersized trees, or roofs angled at 85 degrees instead of 90), he implemented corrections, even adding rocks matching invisible collision boundaries from the isometric art. He even engineered the Tristram skybox, constructed using the brief footage visible during the original cinematic, to achieve an authentic look.

These options receive rigorous foundational support : the HUD is now resizable independently of screen resolution, and isometric zooming is locked to original game values. Drelvak rightly notes that modern port players often experience gameplay heavily zoomed out without realizing it, which distorts the original experience. Addable features include an adjustable field of view, instant 1-click reversion to original 4:3 ratios, 3D mouse sensitivity settings, and the option to disable enemy red halos. Every detail ensures fidelity remains the default setting rather than the exception.

AI in the Loop

Codex as co-pilot, Drelvak as captain

Drelvak states it clearly : this mod was developed with assistance from Codex, OpenAI's programming AI, fed with the source code of DevilutionX and the base game. His personal role centers on vision, creative direction, testing, and adaptation decisions. Achieving results matching his mental imagery required, by his own admission, a surprising amount of experimentation.

Where Does the Project Stand, Precisely ?

Solid progress, level by level

• The cathedral is complete, serving as the first prototype milestone : the Butcher is already fought directly in subjective view.
• The catacombs are nearing completion, with content mastered up to the ninth dungeon level, representing, in Drelvak's words, "roughly half the game". Every tile, pillar, and arch is carefully reviewed since these conversion rules will serve as a baseline for extrapolating the remaining acts.
• Tristram is largely finalized and undergoes continuous iteration driven by community feedback.
• Multiplayer is fully functional, tested in LAN across two distinct machines, keeping original friendly fire intact. That classic cooperative Diablo tension, where poorly aimed attacks can strike teammates, takes on an entirely fresh dimension in first-person. Other players' sprites render surprisingly well, and watching video footage leaves little room for skepticism.
• No release date has been announced : Drelvak advances at a steady pace, dedicating his days to the project, while partly tying future pacing to community interest.

Witness multiplayer in action for yourself :

The roadmap ahead is mapped out : caves and lava levels, followed by the showdown against Diablo himself in subjective view, which the modder anticipates as an unforgettable highlight. Thanks to donor support, he also mentions acquiring a VR headset to explore community-requested virtual reality support. Already, the project inspires others : a separate developer initiated a VR Diablo prototype, explicitly citing Drelvak's showcase video as direct inspiration.

For Us Older Gamers

If you remember the era—the humming CD-ROM drive, nights spent replaying the cathedral, the mounting dread of Black Death monsters permanently chewing away at your maximum health pool with every hit—you understand what this mod represents : playing Diablo precisely as we experienced it in 1996, but from the inside. The corridors we once glanced down from above can now be traversed at ground level with friends, facing the Butcher face to face.

And while a recent BlizzCon 2026 left us craving substance on official announcements, a solo modder carries this level of ambition forward night after night. It reminds us why the modding community exists and why it matters just as much as official studio releases.

FAQ : Diablo 1 in First-Person View

Is Drelvak's Diablo First Person mod available for download ?

Not yet. The mod page lists its status as "TBA" (To Be Announced). Drelvak ties future milestones partly to public interest while regularly publishing progress videos on YouTube. The cathedral and initial catacombs are fully playable in internal builds.

Do I need to own the original Diablo to run this mod ?

The mod relies on DevilutionX, the open-source port of Diablo and its Hellfire expansion. DevilutionX requires the original game files (MPQ files) to operate. Consequently, you must own a legal copy of the original Diablo.

Is multiplayer supported in this mod ?

Yes, it is fully operational. Drelvak tested it via LAN across two separate machines, with original friendly fire enabled. The results, visible on his YouTube channel, look incredible : other players' sprites integrate naturally into the subjective viewpoint.

Does the mod alter the balancing of the original game ?

No. Drelvak's goal is complete fidelity to the 1996 Diablo : identical procedural generation, identical combat calculations, and authentic vanilla balancing. Visual adjustments (crosshairs, hit markers, item collection prompts) do not affect underlying game mechanics.

Is a VR version planned for Diablo First Person ?

It is on the radar. Drelvak mentioned acquiring a VR headset thanks to community donations to explore the concept. An independent developer even launched a standalone VR Diablo prototype directly inspired by Drelvak's showcase videos.
