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.

i try it but wasn't fun and look like old game and short game , mean you can finish game in 3 Hour cuz in 100 min i fight last boss inside dungeon in 4 or 5 Floor down but i die so not worth buy it
まず思うことはAIだけでここまでゲームとして完成できるのかということ。 このままヴァンサバ系でもできそうな感じ。 世界観は非常にいい。 改善してほしいこと 細い通路に罠が二つあるのはきついかな。 インベントリ出していても行動できると嬉しいかな。 最初で言語を選んだら二度目の起動時は選択不要にしてほしいかな。 まだまだ進化していくと思うゲームで期待大です!
上からの視点のゲームが苦手だったのですがこのゲームは楽しめました ゲーム制や雰囲気の為なのでしょうがMAXにしても暗い印象です ダンジョンも迷宮感があっていい感じだと思います 自分のレベリングが足りなかったせいもあり死にゲーと化しましたがちゃんと攻略すればかなり遣り込めると思います AIだけでもこんなゲームが作れるんですね

A good old-fashioned game! It's a game you'll get completely absorbed in, losing track of time. I can't wait to play the rest! However, I managed to defeat the final boss without really understanding what was going on, so it would have been even better if it had been a little easier to understand.
[h1]このコメントは人間が書いています[/h1] このゲームのコメントは怪しいものが多い はっきりいってゴミ、死んだら何も操作できなくなって説明すらない 安いけどやるだけ無駄、めちゃくちゃ操作しずらいし、日本語も文章だけ操作方法とかは英語。 コントローラーは最適化されていないのでストレスがたまる。 まぁAIが作ったゲームなんてこんなもん。 返金返金
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。
このゲームはレトロだということで侮ってはいけません。 ついクリアしたくてやってしまう力がこのゲームにはあります。 何もかも快適なゲームが楽しいとは限りません。 世界観が好きな人はぜひ一度プレイしてみてください This game may look retro, but don’t underestimate it. It has a certain pull that makes you want to keep playing until you clear it. A game doesn’t have to be perfectly convenient or modern to be fun. If you like its atmosphere and worldbuilding, I definitely recommend giving it a try.
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。
It was fun exploring a dark dungeon filled with enemies and loot. Each of the floors increased in difficulty and it didn't feel too difficult or too easy. I enjoyed the slower pace compared to other ARPGs. Feels more like exploring the unknown rather than destroying an entire ecosystem.
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.
