[DOOM] John Romero's Level Design Rules

During the development of DOOM, John Romero came up with eight special rules to make his levels look and play as good as possible. This video discusses those rules and shows how they were applied all throughout Knee-Deep in the Dead, DOOM's iconic first episode.
For reference, the eight rules are as follows:
1. Always change floor height when changing floor textures. (0:28)
2. Use border textures between different wall segments and doorways. (1:05)
3. Be strict about texture alignment. (1:47)
4. Use contrast between light and dark areas and cramped and open areas. (2:25)
5. Make sure that if the player can see outside, he can somehow get there. (3:13)
6. Be strict about having several secret areas on each level. (3:53)
7. Make levels flow so that the player revisits areas to better understand the 3D space. (4:44)
8. Create several easily-recognizable landmarks for easier navigation. (5:49)

Yeah thats true. :)

[@Phobos_Anomaly]

It's always good to break habits and utilize the new technology. Creating variable heights and non-orthogonal walls was surely a new tool that was hard to start thinking in terms of when they moved from Wolf 3D to Doom. What's the point of the new tech if you're not using it?

[@dotapark]

Huh, I thought he is more creative type than a technical guy.

[@JarlFrank]

That's a good rule. The reason I like Quake more than Doom is its more 3D level design, with rooms above rooms, bridges and all that. Adds a whole new dimension to the game. And a big reason Doom is so superior to all the early 90s Doom clones is that it uses height levels effectively, while most of its clones are as flat as Wolfenstein, which obviously limits level design heavily.

[@ikagura]

That's kinda funny how it's possible to recreate Quake in modern Doom engines now. Also there were some Doom level remade with the Quake engine

[@stormykeep9213]

After playing so much Wolfenstein 3D in '92 '93, it completely blew my mind that you could "see" outside in Doom...and then later when playing discovering that you could actually go outside, nuked my mind! It's little things like that back in those days as games progressed that I miss.

[@YeprilesteR]

Haha that's cool, now the progress is mainly about game physics, engines and VR

[@RainMakeR_Workshop]

He seems to have another rule in: "Show the reward before they can get it". Be it showing keycards, weapons or power ups, Doom often would show the player the reward before they can get to it or they may have already passed a secret access point they can now hunt for.

[@UnchainedEruption]

krulty Be careful with that one though. I’ve seen quite a few wads that try to emulate this but lose sight of what is trying to be achieved by this. For example, Doom the Way id Did does a ton of this. But the levels still feel rather linear, and that thing which you saw earlier isn’t from a diverging or tangential section of the level the player had to discover himself, but rather a necessary locale that came about simply by playing the game normally. So after a while the player catches on to this and stops caring when he notices a key card for example, because he knows he is going to find it later on anyway. The point of those sections is to highlight some powerup or secret location the player might not otherwise have been aware existed, and puts it in the back of the player’s mind, so they’re on the lookout for a possible entrance that will lead to that secret. It’s not meant to be a preview of what’s going to happen inevitably, but rather an open possibility of what the player could discover, if he’s fortunate or skilled enough.

E1M3 did this so well. You see a soul sphere but have to figure out how to get it. You can open a window looking down into a room that you later find a way into. You can see a box of rockets up on a ledge and it tempts you to collect it. I remember when I was little, figuring out all the secrets in that map and feeling so satisfied.

[@thomaseubank1503]

I've taken notes on what Romero said in interviews. Only things that I can add are: 1. Begin the level by asking yourself, "What would be a cool first thing to see?" or, "How can I open this level in an interesting way that makes the player want to explore?" 2. While having landmarks to help with navigation in circular level design, make sure to keep the level somewhat unsymmetrical. It is okay to have small parts symmetrical, but it becomes boring if he whole level is symmetrical. This factors into the contrast of space and lighting mentioned in the video. 3. As soon as your fps becomes too predictable, it is boring.

[@DanielLopez-zt4ig]

His advices are universal, but his creativity has the same limits the Doom engine has.

[@explosiveaddict6939]

The only predictable part of DOOM is the unpredictability. Basically, you walk into a level and you think, "I'm boutta get fucked." Yet it still leaves you wondering _how_ you're getting fucked. Teleporting demons in? Teleporting into demons? Armies of hitscanners? Or, the timeless classic, one massive arena where you're attacked by a wave of demons and you decide to take that one invulnerability in the middle only to find out not long after that there's actually a second, much worse wave and you definitely should've saved the invulnerability. Essentially, you expect something unpredictable to happen yet again-- but you don't know what, nor when, nor how bad it'll be, nor how many save slots you should utilize.

[@DrakathSagittarius]

Quake II has a great example to that second rule. I don't know what the level is called though. The one with four doors across eachother.

[@SparkyMK3]

Romero would definetely agree with 2. He's talked about how much he hates symmetrical level design and finds it boring and uncreative.

I remember about 100 years ago when I tried my hand with a Doom editor (I think it was called DoomEd), I started out a level with a circular room with one door leading out, a spawn point in the center or the room, and had placed two or three demons. As I went further into the level design itself, without having actually fired up the level for testing, my friend walked in and wanted to know how my progress was. I grinned, and decided to show him what I had so far. *I completely forgot,* at the very beginning of the level, right in that circular spawn point room, I had placed a few nasties in there. As soon as I rezzed up in the room, I was chomped by hungry demons within seconds. We were laughing our asses off. "Impressive," he noted. "Well, you at least know how to make levels tough right off the bat." LOL! Ahhh...the good ol' days. Oh, Good Lord, the Hall of Mirrors effect got really annoying if you didn't watch your vertex placement.

[@redenginner]

Romero’s level design rules still should apply to modern games. I freelance game design on my campus (even though i don’t have the courses) and if someone makes a FPS for their senior project i always point to these rules.

[@ScottishAtheist]

It's funny, back in 95 when used to make and play maps with my friends, I'd be following these rules! Of course I was very influenced by the design of the originals. I was obsessed with texture alignment in a way my friends weren't. They could crank out 2 or 3 maps in time I could do one because everything needed a border, everything lined up, the textures would make sense. Same with Duke3D. lol nostalgia. It's very impressive that Romero pioneered the rules whilst Doom itself was new and nothing like it had come before. Geniuses! There's actually three additional rules I followed: 1) Never have an essential switch that needs to be shot to activate, that can't be reached by the player to be "punched" Basically never rely on a resource that might run out to complete the map. 2) If falling into a pit, either have away of escaping, or so much damage it kills you quickly. 3) Always make sure the player can get from the start point to the end point without _requiring_ them to traverse environmental hazards eg Lava - there's a few nasty examples of this rule breaking in E3, Limbo and Mt Erebus. If you should run out of medkits and have really low health you're trapped. This also doesn't really apply to games with recharging health.

[@duLuded]

I know ive fallen into pits and places in some of the official doom wads (maybe within tnt or plutonia) where I fell into a pit and was just stuck. Had to load to get back to where I was

[@ikagura]

Yeah, I hate forced lava/acid passages

[@UnchainedEruption]

ScottishAtheist You can still do 1) and 3) so long as you leave ammo or health near the area that needs to be shot or traversed respectively.

[@UnchainedEruption]

ikagura I like the one in Episode 2 (forget which level) that misleads the player. There’s a hazmat suit that you can use and nearby nukage to cross to reach the door. However, the nukage is very small and can easily be crossed without taking much damage. And if you were perceptive, you may have noticed a couple rooms back there was a very long passageway of nukage which leads to a secret area. If the player is on his first run, he may use the radiation suit for the short nukage right next to it, but a more experienced returning player would be smart enough to realize the most obvious path is not the best one to use the rad suit for. I really appreciate things like that which twist the player’s expectations and break level design conventions, forcing the player to think outside the box.

[@necrosteel5013]

ScottishAtheist toxic floors...oh the horrid memories of having to go down that one secret to a super shotgun in zpack ep1 map 03.and for some fucked up reason the acid pool kills you much faster than it should,its a gimmick level with a timer to add salt on the wound.its still a great map though...

[@StronkiTube]

Correct me if I'm wrong, but I thought one of Romero's rules was also to always allow the player to get out of a pit that he can fall in.

[@guythat1580]

He left it out.

[@NicholasLaRosa0496]

That was something they got wrong in some of the later episodes in DOOM 2. The level design got more unforgiving.

[@guythat1580]

@@NicholasLaRosa0496 I like that kind of design. Many people hate The Chasm but I think that it is a really influential map.

[@joekerwildeDBJ87]

Some pits are meant to be death traps. You fall in, you're dead. Which I find pretty interesting. Simple straight foward trap like crushers.

[@joekerwildeDBJ87]

Examples of deliberately not having a way out best shown in Tricks & Traps (Doom 2). But there's a couple in Ultimate Doom, one in Pandemonium but only if you fall off the wrong side of a bridge (think it's where the Yellow Key Door is)

[@Lemunde]

I wish modern level designers would take a good long look at number 7. There seems to be this mentality that the player should be always moving forward. "Backtracking" isn't a four letter word. It's important that the player get the opportunity to become familiar with the level and be allowed to explore it rather than just have it be a complex but 1 dimensional hallway of enemies.

[@tiefighter3445]

Agree.

[@UnchainedEruption]

Here’s an important one to add: Never have your rooms shaped like rectangles or boxes. If they’re like rectangles, they’re boring to run through and uninteresting to look at. For example, take literally any vanilla map from Knee Deep through Plutonia and look at the level layout from the map view. You will never see any portion have straight lines. Lots of crooked paths that interweave with each other and branch out. Having a linear path is also a mortal sin. The player should be able to explore the map, not follow a single obvious way to go. Another good one (also from Romero himself) is to never use symmetry. Symmetry is lazy because it’s in essence copy/paste, but moreover it’s always better to do something different, to surprise the player.

[@nostrace]

That symmetry rule seems to apply so well with prog music also. The music I listen to the most has sort of an anti-symmetry mentality to it. Without being wacky and messy of course. That's an interesting point you have there!

[@GalokVonGreshnak]

It's interesting you say that with the linear aspect. They designed it so well that when you stumble on a linear path, it was so unnatural that the only thing that went through your mind is: *How many Pinkies are going to pop out of the walls?*

[@mikakorhonen5715]

I hate symmetry maps in RTS games.

[@kosiak10851]

I never experienced Doom and Wolf3d back in the day they were released, and now I'm checking them out. And I have to say, unlike Doom, Wolf has a huge problem. Technical limitations like similar rectangular rooms with same textures and lack of map = Gamedesign limitations and waaay less fun than Doom brings. Because of this, Doom remains a very great game even by todays standarts exactly because of level design. The design that was impossible on previous generation game engine.

[@user-xg8yy7yl1d]

The exception to the linear path I think is some kind of map that isn’t beaten such as a multiplayer map or especially zombies map where you’re supposed to gradually open up parts of the map to begin your survival

[@epIx111333]

[@coffeedude]

[@DSDMovies]

I want to know how did Romero happen to be one of the greatest level designers right ouf ot the gate. He must have learned a few things during Wolfenstein but it's uncanny how Doom, the first FPS with levels that had realistic shapes and contours had such amazing design. Romero must have been thinking about nothing else during that period. Rule 4 about contrasts is particularly insightful.

[@Chubzdoomer]

Yeah, it's incredible how far ahead of the curve he was compared to everyone else, especially artistically.

[@lounowell4171]

its mostly common sense, it just seems remarkable because its so lacking in the industry in modern times

[@UnchainedEruption]

DSDuddles Wolfenstein 3D has all the same genius level design that Doom has, so does Quake. You have to remember he and id had a lot of experience with many different games before putting out Doom. He knows what is fun to play and puts in the game the things he himself likes to see.

[@todesziege]

I believe working with 2D games before going 3D helped. Makes you think more in terms of systems, flow etc rather than "realism".

[@FightingForceSoulless]

Playing a lot of DnD, having a great mind for imagination and also lots of skill prior to ID. He's done plenty of design as a kid/at Softdisk with the guys, so I wouldn't say it was right out of the gate. But I admit, his talent surely gave him a flying start.

[@BalimaarTheBassFish]

I think I also heard somewhere where someone from iD said: "Create your level, make sure you can run it blind folded and call that difficulty hard"

[@Allstin]

One exception is past the green armor. You can see outside, but not able to get out there. And the E1M3 secret with the cage and monsters just below you

[@fezzadork]

There are a lot more examples than that. E1M2 outside the chainsaw room, E1M5 has the window by the rocket launcher secret area, E2M1 behind the start area, E4M5 has a window near the start point, and I’m sure there are others.

[@Kyle07]

Well I think the rule applies to huge "cool" areas, were the player wants to get outside, like E1M1.

[@Lattamonsteri]

Yea the rule should be: if you see (enemies or) items outside, you should be able to (kill or) get them.

[@JimBimBum]

I don't the exception is the rule is null if the windows are near an object that's meant to get your attention.

[@INFILTR8US]

Petty much?

[@blueblimp]

The rules show how important exploration is to the Romero style of level design. Rules 5-8 are all about giving the level good exploration gameplay. One particular thing about Doom is the fast player speed means that you can backtrack a lot without getting bored. It's so dull to backtrack in games where you move slowly, which hurts the exploration experience.

[@MidnightSt]

Yeah, most of those rules are still relevant, and those which kinda aren't can be updated: wall texture transitions - put a divider texture in between could be made into - wall changes (corridor to room, change in room width/height/shape) don't just have them as plain geometry edges or connectors of two straight wall prefabs - put some kind of nice and kinda plausible/natural joint/divider on that spot. that's what door frames are in reality, for example. notice how many of the transition textures in doom are precisely that. also, then, turn it up a bit, because you will also notice in normal buildings in reality things like this are rare, most corners are clean... but games are not reality, they are hyperreality, so to feel as real as reality, they must exaggerate everything.

[@jameswalker199]

On the point about creating memorable landmarks, this is very relevant to modern games. I've heard the concept called "weenees" before, but I think that more often refers to large landmarks that the player can *see* from most places on the map, rather than a location the player *remembers* to return to.

Joel from Vinesauce is running a competition on Doom maps and mods. 240 .wads in this competition and he's running through them all. With the new advancements in the Doom engine, people have been creating some really cool maps even while completely disregarding these rules. One major mistake I see people do all the time is that if you are going to have non obvious weapon pickups, make sure you eiter place them clearly visible from the player's path, so he can hunt for the entry, or you put many weapon pickups throughout the map. Many times I've seen Joel reach the end of the map with a full complement of ammo, but withouth the weapon to use it, because it was in that obscure room he had to backtrack for.

Excellent video. One thing I've always loved about the first episode is how the great deal of windows and rooms without ceilings contribute to a sort of open floor plan spacious feeling while contrasting it to smaller, darker and more cramped spaces.

The texture alignement may sound a bit obvious, but we have to consider: back then they didn't had a fancy doom builder with 3d viewing and autoalign functions, they had to manually type the offsets values for each linedef, save, close the editor then open the game and test it live. So aligning textures was more of a pain and methodic procedure than what we have today.

[@GameplayandTalk]

Great video! They really focused on attention to detail with this game, which is a fantastic result of these rules.

[@Sketchy3032]

Wanna add my own: - There should be no doors/platforms that makes the players wait because of its slow opening, raising, or lowering animation. If you want to preserve the epicness of it, they should be able to bypass it or at least cut the waiting time simply by running really fast, jumping, or crouching through it. - Large decorations, landmarks or those that involve using sectors (i.e. furniture, machinery, pillars) should be placed in a way to also serve as cover for players from projectiles from monsters. - There should always be a designated room where others often lead to in that is filled with health and ammo for players to recover in each level. Small pickups should be scattered in the rest of the map, and large ones are either hidden or placed in this.

[@n0isyturtle]

I would like to add - NO JUMPING PUZZLES, but he doesn't subscribe to the belief of that momentum-killing unending source of frustration that devs _still_ put into fps games even now. Also anything that is an insta-kill which doesn't allow the player to react properly without prior knowledge of said insta-kill.

[@ScileSc]

Jumping puzzles can be fun as long as you don´t overdo it with the difficulty. Platformer level structures can even be used to take advantage during combat.

The first EP of Doom is still probably hands down my favorite EP out of the bunch. It also helps that it was shareware, hence distributed for free (or for a small fee via compilation discs) so i'm sure that many people remember playing this episode a TON as i did (even though i didn't actually play it in the 90's).

Texture alignment is something i took VERY serious when working on maps for Quake III Arena. It just had to feel as seamless as possible.

[@jojo-dr1ti]

really great content, each of the things you pointed out are things that I accepted subliminally when playing those games, and they were each also things that were noticeably missing from mods.

[@ScampiTheSighted]

Remember when designing levels: You need to assess the load-bearing capabilities of structures! Unless you can determine the material/s, mass, geometry and strength of each and every brush a level is made of based on their textures and dimensions, and how they interact with each other, you may inadvertently create structures that would COLLAPSE! In addition, you need to predict local weather conditions and seismic activity based on the game lore and skybox texture, and design your levels accordingly! If your structures aren't up to good engineering standards, or at least local building codes, you could endanger the lives of space marines/demons inside and get ARRESTED! This is why level design takes so long, guys.

[@boggers]

Wasn't Doom set on Phobos, where there is no atmosphere, the gravity is about two thousand times weaker than Earth, it's tide locked to Mars and solid rock all the way through? Just saying, you don't really need to worry about load bearing capabilities, weather or seismic activity on Phobos, you got a whole different set of engineering challenges though, like how to make sure people don't run faster than the escape velocity.

These sound very simplistic to be honest. Then again he was the original Doom mapper in the first place.

[@alexanderstephens822]

They ARE simplistic. Being able to follow these rules only makes someone a half-decent beginner level designer. There is so much more that goes into making a fun level

[@ikagura]

Doom is simplistic, that's why it's still good today

[@UnchainedEruption]

splattenburgers Then what do you suggest as a non-“simplistic” tip?

[@skaruts]

They're not general rules of map design, they are specific to doom/quake style level design. They're also specific for single player maps. In a multiplayer map you'd have rules like _"make walls flat; all protruding parts non-solid",_ which is a rule Valve didn't know about when making TF2 stock maps...

All the backtracking in the levels of Doom is probably its weakest design choice.

[@tiefighter3445]

Backtracking was the best part of Doom because it forced you to solve the puzzle aspects of the game. Doom games did not hold your hand if you wanted out you had to really work for it. If it was just gun everything down the end it would have gotten boring fast.

[@BlazingOwnager]

You're entirely correct, every rule on the entire list is absolutely top tier advice that never became outdated. It's all as good today as it was then. The only possible exception being breaking up floor textures without height changes, but that's only because we have the tech and memory to shuffle several compatible floor textures and break up flow. But as general advice, it's still good.

[@JohnLucPicard98]

[@nightbirdds]

Nice breakdown, Chubz. What's shocking is that these rules feel totally natural. In following them, you inevitably end up creating areas that feel like real spaces. That's what John's levels were able to do, even with the limited resources of Vanilla doom at the time. Knowing these rules though, also lets you tactically break them where the situation warrants. Been using your tutorials as reference material to get myself up to speed again. They're coming in handy in making the transition from the last port we used to GZDoom. Peace.

Finally a good video about level design thanks for make it

[@SplotchTheCatThing]

Yeah, I've used a lot of these principles when I've been mapping for older games like Doom and Descent. Mostly got them from observing the sorts of designers I wanted to imitate and analyzing what made their designs "good", but it's interesting to see it quantified like this. There's another one that's served me very well (and which I also see in Romero's designs) which is that when you're putting an important object like a door, or even a decoration texture, onto a square wall, it's useful to create a little indentation in front of it rather than placing it flush with the wall itself. It helps the object stick out to the player as "not just another wall panel" especially in older engines where the texture is otherwise the only thing that tells you "hey this bit of wall looks a door". I've found it particularly useful in Descent where, unlike in Doom, the doors themselves have no depth -- so the indentation serves an extra purpose of denying the player any reference frame for the door's "flatness" and making it look a little more convincing -- but I still see it done for most non-secret doors on Romero's levels and many others in Doom, and it does tend to make them look better and stick out as "important".

The first episode and its maps have always been my favourite of all episodes and maps ever done in Doom. Now I know why :)
