Overview

What if the floppy disk on your desk wasn't just a relic of the past, but a gateway to a nightmare? That's the premise of Diskette Dungeon, a 3D action roguelike dungeon crawler developed and published by MM88.

Released on November 4, 2026, this indie title blends medieval fantasy with a corrupted digital world trapped inside an old diskette. You play as an ordinary office worker who presses "PLAY" and suddenly finds themselves fighting for survival in a labyrinth of glitched-out dungeons.

The game supports single-player and Family Sharing, and it's fully localized in 16 languages, including Japanese, English, and Simplified Chinese.

Highlights

  • Action Roguelike Dungeon Crawling: Each run throws you into procedurally generated dungeons where forgotten technology and ancient magic have fused into dangerous enemies and traps.
  • Perma Death and Learning: Death is permanent, but every failure teaches you something new. Adapt, improvise, and start again—that's the core loop.
  • Office Worker Protagonist: You're not a hero or a chosen one. You're just someone who pressed "PLAY" on a mysterious diskette. The contrast between mundane office life and chaotic dungeon crawling is a key part of the game's charm.

Who It's For

If you enjoy action roguelikes with a strong sense of humor and a unique setting, Diskette Dungeon is worth a look. The game's blend of office satire and dungeon crawling will appeal to fans of games like The Binding of Isaac or Hades, but with a distinctly digital twist.

It's also a great pick for players who appreciate games that don't take themselves too seriously, yet still offer a solid challenge. Since it's a single-player experience, it's perfect for those who prefer to dive into a dungeon alone, though the description hints at the possibility of playing with friends—though the Steam metadata only lists single-player, so check the latest store listing for any updates.
