About
■ About development
A solo development work by a 45-year-old with no programming experience who wrote approximately 120,000 lines of code and 100 achievements in 3 months using only AI.
The only development partner is Anthropic's AI agent "Claude Code." I don't use Unity or Unreal, I created my own custom engine and map editor. There is not a single line of code or specifications written by humans. All 100 Steam achievements are automatically generated by AI.
Subtitles are available in 95 languages and full audio dubbing is available in 70 languages. All translation, dubbing, and quality checks are performed using AI.
■ Story
1997.
A great king was killed by a flame called the Fire Field.
Rainz killed the king.
The world hated him.
However, on the other hand, there were a small number of people who worshiped him as a savior.
As one of the "people of Rainz," you step into the cemetery in the north where the king is buried.
No one who goes down to the basement of the cemetery ever returns.
Is the truth of the king sleeping there? Rainz's sin? Or is it an inherited curse?
Fire Field is a dark fantasy action RPG that takes you deep underground.
■ What you can currently play
In the current version, you can explore up to the 5th floor underground.
Enemies become stronger each time you go down a floor, and a boss awaits you at the deepest level.
Your goal is to equip yourself in the city, advance underground one layer at a time, and survive as you dive deeper.
■ Features
・Dungeon exploration gets more and more tense as you go underground
・Underground structure that changes every time you explore
・More than 100,000 equipment variations, hack and slash elements
・Item system that gives different abilities to each piece of equipment
・Customization and appearance changes for each equipment part
・A system where you become a ghost when you die and wander through the reverberations that remain underground.
・A fragmented story about Rainz, the King, and the Fire Field.
・Rough and cold visual expression with the atmosphere of the 90s in mind
・Battle with the boss waiting in the depths
■ Supported languages
・Subtitles: Supports 95 languages around the world (all translated by AI)
・Audio: Supports full dubbing in 70 languages (all generated by AI)
・Supported platform: Windows
■ About Early Access
Through Early Access, Fire Field aims to further expand its underworld, enemies, and story.
This work is currently being developed primarily as a single-player experience.
As part of our future roadmap, we are planning to implement Steam Deck compatibility, a Mac version, and online co-op play.
■ About Fire Field
Fire Field is a work based on the theme, "People disappear, but the cause remains."
The deeper you go underground, the more you gradually uncover what happened in the past and what the flames left behind.
This is still the beginning of the story. But the flames are already burning.

Reviews
If you're a fan of Ultima and Diablo you've found the game for you :). Rooted in deep Ultima Online lore laid atop lovingly crafted old school Diablo gameplay, this is a fun little romp, especially for an Early Access title.
まるで90年代にタイムスリップしたかのような雰囲気、ゲーム性でした。 AIを使って制作したとのことですが、ゲームとして破綻することなく楽しくプレイできます。 開発経験ゼロからのスタートでソロ制作の1作目がこの出来とは一昔前では考えられないですね。 今後の展開にも期待してます。
90年代のDiabloライクなARPGで、当時の懐かしさを感じられます。アイテムのレアリティや、魔法のレベルアップシステム、武器によって、スキルが変わるところがとても良かった。 グラフィックなど、まだ荒削りな部分もありますが、開発者が頻繁にアップデートを重ねていて、コメントからも強い熱意が伝わってきた。今度の期待を込めてこの評価にさせてもらいました。
多分、アップデートのせいだと思うけど、レベルとイベントの進行がリセットされてるんだけど。たいして進んでなかったので被害少ないとはいえ、この手の不具合、1番やる気をなくす要因だと思う。
Diabloやルナティックドーンが好きなので物は試しということで買ってみた 現段階ではAI Slopと言われても仕方ない サクラレビューのようなものもあるのでマーケティングも怪しい
Good game ? No Good Sport ? Yes
まず思ったのが、AIだけでゲームを作れるんだ!? レトロ・ダークな世界観は正直あまり得意ではありませんでした。 でもやっていくうちにどんどん進みたくなる中毒性があります。 しっかりやり込んでいけば、より面白くなるゲームだと思いました。
Honestly, I think it really comes down to what you're looking for in this game. I gotta give huge props to the developer for building something this solid entirely with AI, especially with zero coding knowledge. This isn't just some casual mobile app; it's got a lot of depth and grind to it. Sure, it doesn't have the flashy innovation, fast-paced action, or 3D graphics of modern titles, but it has this nostalgic vibe... It genuinely feels like you're playing a game straight out of the 90s. There's this low-key satisfaction in slowly taking down enemies, grabbing loot, and leveling up, which naturally opens up new paths forward. The dev is actively taking feedback and tweaking the game step by step. It's fun right now, but I'm definitely looking forward to seeing how it evolves.
This game has some real potential. Regardless if it's AI, the game is close to a grasp at a feel for something great. There needs to be more features that need to be added, the game is relatively short to beat if you have a moderate experience with arpgs, and I didn't die a single time except near the final boss where I was at my last pot from a full inventory. I would recommend to just support the developer of this game if you want something close to Diablo 1, because currently there is literally nothing like Diablo 1 and this was the closest thing I've ever played in recent years that comes close to it. Some of the pathing could be better and soundmixing of barrel explosions. The stash quest is bugged, but really the game isn't long enough yet for any repeats, but for 3 months of work this is extremely impressive and I would really enjoy an ironman mode with much more stats, a slower movement pacing, and more emphasis on positioning. There is a lot more work put in than some garbage AI asset vomit, and the game has a good sense of cohesion for visuals. There is a lot of ideas brewing in my head for this game and it has a lot of good things it can amount to. When this game is more polished, has a ton more content, I would definitely recommend this game more and think it can be something I can play for hundreds of hours just like Diablo 1 The Hell Mods.
