ADOM, short for Ancient Domains of Mystery, is one of the all-time great roguelikes, and its classic version is free. Created by Thomas Biskup back in 1994, it sends you into the Drakalor Chain to stop the encroaching forces of Chaos, and it stands out from its peers by wrapping the usual dungeon-diving in an actual story, an overworld map, quests, NPCs, and multiple endings. It’s regularly named one of the “major roguelikes” for good reason.
Where most roguelikes are pure dungeon crawls, ADOM feels more like a full RPG. You travel a world map between dungeons and towns, take on quests, and shape a deep character through races, classes, skills, and star signs. Its signature twist is Corruption: the Chaos you’re fighting slowly warps your character, granting strange powers at the risk of monstrous mutation. Turn-based and permadeath, of course, so every decision carries weight.
It’s a beloved entry on our list of the best free roguelike games for PC, and one of the most story-rich the genre has to offer.
Is ADOM Free?
Yes. The classic version of ADOM is free, downloadable directly from the official site, and these days the free release even includes a graphical version with tiles and music alongside the traditional ASCII build. It’s genuine freeware, with no ads and no microtransactions, though it isn’t open source.
There’s also a paid Deluxe version on Steam and GOG (around $15). It adds Steam achievements, difficulty customization, and extra play modes, a story mode that lets you save and reload, a weekly challenge, an exploration mode, and more, on top of the core game. If you want those conveniences, the paid version delivers. But the free version is the complete, authentic ADOM at no cost.
Gameplay & Features
ADOM plays like a roguelike crossed with a classic RPG. You begin by creating a character, choosing a race, class, and star sign, then set out across an overworld map dotted with dungeons, towns, and quest sites. Combat is turn-based and grid-based, dungeons are procedurally generated (and stay fixed once created), and death is permanent.
The story is what sets it apart. There’s a genuine plot about holding back Chaos, complete with named NPCs, side quests, and several possible endings depending on your choices. And then there’s Corruption, the mechanic everyone remembers: exposure to Chaos mutates your character over time, handing out powers you might love or transformations you’ll dread. It’s deep, it’s punishing, and it’s endlessly replayable.
- A story-driven world with an overworld map, towns, quests, NPCs, and multiple endings.
- Deep character creation across races, classes, skills, and star signs.
- The signature Corruption system, where fighting Chaos slowly and dangerously mutates you.
- Classic ASCII or a graphical tiles-and-music version, both free.
For more of the genre’s classics, NetHack and Angband are the other legendary “major roguelikes” worth diving into.
PC System Requirements
ADOM is very light. The ASCII version is tiny, and even the full graphical build with tiles and music is a modest download. Any modern PC runs it comfortably. There’s no official spec sheet, so the figures below are a practical guide.
| Component | Minimum | Recommended |
|---|---|---|
| OS | Windows XP or later (also macOS and Linux) | Windows 10 or later |
| Processor | 1 GHz or faster | Any modern CPU |
| Memory | 512 MB RAM | 2 GB RAM |
| Graphics | DirectX 9 / OpenGL compatible | Integrated graphics or better |
| Storage | 500 MB available space (graphical build) | 500 MB available space |
The ASCII-only build is a fraction of that size, if you’d rather keep things lean.
