Typology
Abstract layout patterns for level design, with concrete examples
What's a typology?
A typology is a layout design pattern, a class system that helps us think about layouts. It abstracts the layout -- it simplifies and generalizes the structure.
In the real world architecture diagram above, Maja Baldea thinks about different ways to organize apartment buildings. She abstracts (simplifies, generalizes) these buildings as windowless blocks because she's not interested in little details, she's thinking about the overall shape, massing, and composition, to classify different types of residential buildings.
Typologies are useful for:
classifying different types of level design
open world / battle royale type projects, since a variety of typologies will usually lead to a variety of game content
shared design language, aids collaboration and teamwork
Elements
Beyond walls, floors, and ceilings, there's also some common gameplay elements frequently found in most levels:
Cover. Half cover vs. full cover, hard cover vs. soft cover.
Gates. Hard gate vs. soft gate, lock and key, forward gating vs. backward gating.
Room typologies
Room typologies are generalized patterns for a single area / "chunk" of the level.
Corridor
Straight-on linear progression through the space, like a hallway, river, or canyon. Anything with a one-way trajectory through a predictable sequence of spaces could be considered a corridor.
High degree of authorship, control, and certainty. You know where the player must go and how much time the player will likely take.
To speed it up, add downward slopes, one-way drops, and bright lighting
To slow it down, add side areas, alcoves, and spotty lighting
Corridor example: house in P.T
The first person horror game P.T. (2014) made players walk down the same hallways over and over, with a looping mechanic that teleports the player back to the start once they open the door at the end. It is a powerful use of the corridor, and would've suffered with a more open layout.
Note the strong control of sightlines, forcing the player to stare through a window at the corner, or to detour into the bathroom to notice the mirror and sink. Horror tropes and ominous alcoves discourage players from moving too quickly, while linearity and familiarity culminate in a sense of foreboding, dread, and doom. All we can do is go deeper, and there is no escape.
Switchback / Hairpin
A dead-end corridor with a visible exit when you backtrack.
Similar to corridor, offers a lot of control and authorship
Obscuring the exit encourages the player to explore the dead-end first
Brief confusion, mild sense of exploration and navigation
Switchback example: cave in Dear Esther
Ring Around The Rosie / Combat Bowl
Small open area with cover in the middle, usually full cover like a pillar or column, resulting in a spinning / rotating flow. Especially common in fast-paced combat games, where players can "dance" / circle-strafe around the central cover while blocking enemy attacks.
Add a one-way drop to force a specific flow, and/or introduce some verticality
Arena / Point of Interest (POI)
An arena is an open area with several lanes of circulation and some cover in the middle.
open world and battle royale designers use points of interest (POIs), big arenas anchored by a large landmark with multiple entrances and exits
in single player, arenas usually need gating; gate players from leaving the arena early, but also gate the entrance to prevent players from pulling all the enemies into a chokepoint
Example: Dead Simple in Doom 2
(TODO: draw Dead Simple floorplan and critical path)
Level typologies
Level typologies are generalized layout patterns for multiple rooms / entire levels.
Hub-and-spoke
A larger multi-area pattern with a central area (hub) and several smaller areas / passages extending off of it (spokes). To explore different spokes, the player must return to the hub.
Gives unifying identity to different spokes, conveys logic to the structure
Needs lots of work to update the hub with each visit, or else it'll feel like backtracking
Can be a useful pacing tool, returning to a hub can feel like a relaxing reward
Gated hubs block off most spokes at the start, the player gradually unlocks shortcuts
Example: Medical Pavilion in BioShock 1
BioShock 1 features multiple hub-and-spokes. In the beginning Medical Pavilion chapter 1
Loopback
(TODO: diagram)
A linear progression that loops back on itself, most common in open world dungeons.
Similar to Corridor: lots of control and certainty with less player indecision
Helps an area feel structurally non-linear and plausible, even if progression is initially linear
Subtle loopbacks feel like closing the loop of a natural inevitable circuit
Overly convenient loopbacks can feel like contrived shortcuts that plead for the player's gratitude, and thus feel artificial or implausible
Example: (some dungeon) in Skyrim
(example: skyrim layout and screenshot)
The open world fantasy RPG Skyrim features many dungeons where the player must return to the overworld after completing the dungeon. However, backtracking often feels monotonous or rote after an area has been cleared out... (TODO: finish)
Branching chokepoints / string of pearls
Pass-through
Time cave
Multiplayer typologies
Multiplayer layouts tend to be more nonlinear, circuitous, and bidirectional, emphasizing high replay value with reusable areas. Many team-based games feature bases / spawn rooms where players can safely join the game, as well as capture points for the teams to attack and defend.
Base / spawn room
No man's land
Sniper nest / sniper alley
Figure 8
most common in classic CTF maps, Blood Gulch, etc
Connector / Pivot
In multiplayer team games with bases and routes toward capture points
Example: CS:GO
Three lane
Example: League of Legends, DOTA, Call of Duty: Modern Warfare... also common in CS:GO (1 lane for each bomb site, and middle connector lane)
Against typology?
Once you classify something, you're potentially trapping yourself within the limits of those classifications. Sometimes it may be more helpful to ignore typologies and refuse categorization.
To review...
A typology is a way to classify different categories of level layouts. These words and labels help us talk and think about layout.
Room typologies are patterns for designing single areas, like corridors, switchbacks, ring-around-the-rosies / combat bowls, and arenas / POIs.
Level typologies are patterns arranging multiple rooms in sequence, like loopback, pass-through, branch and bottleneck, hub-and-spoke, and time cave.

"On the ‘Three Typologies’" (2017) by architect Luke Jones is a wonderful essay about how architects still aren't quite sure how to classify architecture.
