Cyber Dungeon DX

About the game

Cyber Dungeon DX swaps torches for flashlights and skeletons for security drones. You descend into the abandoned data-fortress of a collapsed megacorp, one grid-square at a time, managing batteries instead of torches and firmware instead of spells. Every floor is a self-contained puzzle box of locked bulkheads, maintenance shafts and terminals written in a surprisingly readable in-game scripting language.

What made it a cult classic is the augment system. Every implant has a cost: better vision drains power faster, a faster stride makes noise that wakes drones. By floor thirty you are a walking trade-off, and the game knows it. The DX edition added an automap — grudgingly, the manual jokes — and a second ending for players who finish without ever triggering an alarm.

Technical notes

Grid-based movement at 90-degree turns, with a real-time drone patrol layer running underneath — an unusual hybrid for 1995. The terminal mini-language is a genuine tiny interpreter, and speedrunners still abuse it.
