Levels are the heart of DoomRL, and without them there would be no game. It is where the player explores, where enemies roam, where special items lie in wait. They are filled with either fortune or your own personal doom.
Random levels
The archetypical level in DoomRL is a randomly-generated one. It is produced in such a way that no two games are particularly alike. There are many special considerations within the game engine, although many of these are technical and unimportant from a gameplay perspective.
Special levels
In stark contrast to random levels, special levels are constant and many of them appear every game. As you gain more experience playing DoomRL, these become stepping stones used as a grip against the turbulent flow of random levels.
For obvious reasons, all of these pages are considered spoilers if you wish to learn how to beat them yourself. Some are particularly spoiler-heavy, though, and are indicated as such here.

Special level placement

Special levels (besides Phobos Base Entry, Hellgate, Phobos Arena, and Hell Fortress) each have a dlevel range and a probability of appearing. When a new game starts, the program iterates through the special levels. For each, it rolls to determine if the level spawns, then, if so, chooses a dlevel from the range and places the special level there. If another special level later chooses the same dlevel, then the first special level is overwritten. Thus, the order of iteration is important. The order is: The Wall, The Lava Pits, City of Skulls, The Mortuary, The Vaults, Hell's Arena, Unholy Cathedral, Spider's Lair, Hell's Armory, Halls of Carnage, The Chained Court.
The following table summarizes the probabilities and dlevel ranges, with a separate column for the probability one overwriting is accounted for (which is what players will observe).
| Level | Range | Probability (base) | Probability (actual) |
| Hell's Arena | 2-3 | 100% | 100% |
| The Chained Court | 4-6 | 100% | 100% |
| The Wall | 7-13 | 100% | 11/28 = 39.3% |
| Hell's Armory | 9-10 | 100% | 100% |
| Halls of Carnage | 11-14 | 100% | 100% |
| Unholy Cathedral | 16 | 100% | 100% |
| City of Skulls | 17 | 40% | 40% |
| Spider's Lair | 18-19 | 40% | 40% |
| The Vaults | 18-21 | 100% | 90% |
| The Mortuary | 22 | 100% | 100% |
| The Lava Pits | 23 | 100% | 100% |
Additionally, some levels don't spawn on I'm Too Young To Die: Hell's Armory, Unholy Cathedral, The Vaults, and The Mortuary. This means that The Wall is more common on that difficulty level: 19/28 = 67.9%.
Also, for those levels that get overridden, the likelihood of appearing on different levels is skewed.
Here is a table showing the distribution of which specials stairs are likely to be on each level assuming there are stairs and that none of the possible levels have been encountered previously.
| Level | Special Level |
| 1 | N/A |
| 2-3 | always Hell's Arena |
| 4-6 | always Chained Court |
| 7-8 | always The Wall |
| 9-10 | always The Armory (on I'm Too Young To Die, always The Wall) |
| 11 | 5/8 Halls of Carnage, 3/8 The Wall (on I'm Too Young To Die, 1/2 Halls of Carnage, 1/2 The Wall) |
| 12 | 2/3 Halls of Carnage, 1/3 The Wall (on I'm Too Young To Die, 1/2 Halls of Carnage, 1/2 The Wall) |
| 13 | 3/4 Halls of Carnage, 1/4 The Wall (on I'm Too Young To Die, 1/2 Halls of Carnage, 1/2 The Wall) |
| 14 | always Halls of Carnage |
| 15 | N/A |
| 16 | always Unholy Cathedral |
| 17 | always City of Skulls |
| 18-19 | 1/2 The Vaults, 1/2 Spider's Lair (on I'm Too Young To Die, always Spider's Lair) |
| 20-21 | always The Vaults |
| 22 | always The Mortuary |
| 23 | always The Lava Pits |
| >23 | N/A |
Special stairs are always placed on a random empty tile.
