Levels

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.

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.

• Level type
• Level feeling
• Level event
• Monster Generation
• Item Generation
• Room Generation
• Fluids

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 otherwise (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.
