Play Oni IV : Kishin no Ketsuzoku Online

Oni IV: Kishin no Ketsuzoku was a Japan-only release for the original Game Boy, developed by Athena and published by I'Max in 1993. It arrived late in the system's life, a time when developers were still finding ways to push the hardware with deeper, more complex adventures. The game stands as the fourth entry in a relatively obscure series, offering a dark fantasy experience that felt distinct among the platform's library.

You control a lone warrior navigating maze-like dungeons, clearing rooms of monsters screen by screen. Your main goal is to defeat powerful bosses and gather key items to progress deeper into the cursed strongholds. Combat relies on close-range sword slashes and careful positioning to avoid enemy attacks; some foes require specific tactics or timing to defeat. The pacing is deliberate, with backtracking and resource management playing a role, and the difficulty can be unforgiving due to limited healing and aggressive enemies. It feels tense and methodical, demanding patience and observation in every shadowy corridor.
