About the game
■ 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.

■ 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.
