Overview

About this game

WHY IS THERE A MAGICAL PORTAL IN THE OFFICE?

A mysterious diskette has appeared on your office desk. What should have been just another workday turns into a plunge into a labyrinth of corrupted dungeons, where forgotten technology and ancient magic collide. You are not a hero. You are not chosen. You are simply the one who pressed RUN. Survival is all that matters now. Adapt, improvise, or start over alone or with friends.

YOU ARE JUST AN OFFICE WORKER. TRY TO SURVIVE!

Diskette Dungeon is a 3D action roguelike dungeon crawler playable solo or in co-op. Every death resets your run, but each attempt teaches you something new. Venture through portals alone, or team up to combine skills, builds, and strategies to push deeper into the ever-changing dungeons. Victory is possible only through coordination, learning, and persistence.

The dungeons are alive and reactive. Destroy walls, flood areas, trigger explosions, push barrels, and manipulate traps and hazards to your advantage. Enemies, objects, and environments release corrupted data, the only currency in the game. Spend it wisely to unlock portals, access new worlds, purchase abilities, weapons, and items, and shape both individual and team builds. How you manage your corrupted data can mean success or failure.

Explore over ten distinct biomes, each with unique rules, enemies, and hazards, from ancient ruins and poisoned jungles to sewers, graveyards, hellish realms, and corrupted systems. No two runs are ever the same. Dungeons mutate, random events can reshape entire levels, and neutral creatures may fight each other, creating dynamic challenges that demand quick thinking and adaptability.

Diskette Dungeon fuses medieval fantasy with obsolete technology, blending steel, bones, and magic with diskettes, corrupted files, green terminal-style interfaces, system messages, and broken code. Software logic becomes magic, and the world around you is as reactive as it is dangerous.
