■ 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.

■ 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.
