Also, some objects have two versions: one that can be destroyed and one that can't.

In stark contrast to random levels, special levels are constant and many of them appear every game. A few are static levels you must always go through on their designated floors (with the exception of certain challenges disabling them), while the rest are optional levels you may enter inbetween floors if you find the stairs to them (the entry to which are highlighted by red stairs). Each special level tends to have a gimmick to it, and completing them without the right equipment and plan can be very difficult, especially so on harder difficulties, but they offer great rewards that you will have a hard time procuring normally (or even be unable to obtain at all otherwise), as well as substantial EXP to level you up to a greater degree.

Special stairs are always placed on a random empty tile.
  
−
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.
+
Special level pairs are chosen randomly - exactly one from each pair appears per game.

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.

Basic Objects

All levels are made of basic objects like floors, walls, and doors.

  • HP: This is one of the parameters that governs how difficult the object is to destroy. Whenever an object takes damage, its HP is decreased. Once its HP falls to 0, it changes to a floor tile. Some objects cannot be destroyed; these are indicated as "none". Also, some objects have two versions: one that can be destroyed and one that can't.
  • Armor: This also makes objects harder to destroy. Whenever an object takes damage, the object's armor is subtracted from the damage before the damage is subtracted from HP. Unlike the armor of the player and enemies, objects' armor can reduce damage to 0.
  • Fragile: Objects can usually only be damaged by plasma, fire, or acid damage. Fragile objects can be damaged by any damage type.

barrel of acid 0 2 4 yes Can be pushed. When destroyed, creates a radius 3 explosion dealing 6d6 acid damage, sometimes leaving behind acid tiles.
barrel of napalm 0 2 5 yes Can be pushed. When destroyed, creates a radius 2 explosion dealing 7d7 fire damage, sometimes (often) leaving behind lava tiles.

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. A few are static levels you must always go through on their designated floors (with the exception of certain challenges disabling them), while the rest are optional levels you may enter inbetween floors if you find the stairs to them (the entry to which are highlighted by red stairs). Each special level tends to have a gimmick to it, and completing them without the right equipment and plan can be very difficult, especially so on harder difficulties, but they offer great rewards that you will have a hard time procuring normally (or even be unable to obtain at all otherwise), as well as substantial EXP to level you up to a greater degree.

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

Some levels don't spawn on I'm Too Young To Die: Hell's Armory/Deimos Lab, The Vaults/House of Pain, Unholy Cathedral, and The Mortuary/Limbo.

Special stairs are always placed on a random empty tile.

Special level pairs are chosen randomly - exactly one from each pair appears per game.

Level Depth
Hell's Arena 2 (Phobos 2)
The Chained Court 5 (Phobos 5)
Phobos Lab/Military Base 7 (Phobos 7)
Hell's Armory/Deimos Lab 9 (Deimos 1)
The Wall/Containment Area 11 (Deimos 3)
City of Skulls/Abyssal Plains 12 (Deimos 4)
Spider's Lair/Halls of Carnage 14 (Deimos 6)
The Vaults/House of Pain 17 (Hell 1)
Unholy Cathedral 19 (Hell 3)
The Mortuary/Limbo 20 (Hell 4)
The Lava Pits/Mt. Erebus 22 (Hell 6)
