Crawl through dungeons using a puzzle/match-3-like system for combat
Equip your adventurers with the loot you find
Invest gold into upgrades to enhance your adventure guild
Solve quests to gain additional rewards
Use the workshop to further improve your equipment
Play around with the various gimmicks you find in the operating system
Enjoy retro music made with the original sound chip of the Sega Genesis


Clearing dungeons and quests will reward you with gold and items. Use them to equip your adventurers!


Each artifact can be found in increasingly difficult dungeons. Are you ready to discover them?


The soundtrack of DungeonOS was created using the original sound chip of the Sega Genesis using the Mega MIDI Synthesizer by Aidan Lawrence and other synths that contain old console chips. We don't use digital VSTs, only hardware synths for the true analog feel!
