This article is about the constructable building only. For natural and smoothed walls, see Structure.

Walls are impassable structures primarily used to create rooms.

Acquisition

Walls are built and repaired by colonists assigned to construct. Walls are constructed with 5 Stuff (Metallic/Woody/Stony, 50 for SMVs) and take 135 ticks (2.25 secs) to build.

Wall construction may sometimes fail and waste the materials, more often with lower construction skill.

Summary

Walls are impassible objects, blocking both movement and line of fire. Pawns can't move through diagonal gaps of walls or other terrain. An area enclosed by impassible objects, including doors, is considered a room. Walls can also support roofing, up to 6 tiles away in all directions. If walls, columns, and other supporting objects are removed, then the roof will fall and injure any pawn below it.

Power conduits can be constructed below a wall, negating the conduit's beauty penalty.

Walls also provide excellent cover from projectile attacks, blocking 75% of shots. Pawns will "peek" from a wall and fire to its side.

Special

Certain damage types are designed to deal more damage to impassible terrain, and to walls specifically:

Walls take 8x damage from Bomb type damage; 4x from being an impassable, and 2x for being a wall
Walls take 30x damage from Thump type damage; 15x from being an impassable, and 2x for being a wall
Walls take 7.5x damage from Breach type damage; 10x from being impassable, but 0.75x for being a wall

Meditation

Ascetics can meditate at a wall for a Meditation Focus Strength of 22%.

Analysis

Walls, or natural rock, are practically essential to create rooms and defensive structures. It's certainly possible to create a room of doors or coolers, but that is just more expensive. As impassible structures, they are important when controling enemy flow and creating killboxes. Sapper and breach raids will explicitly try and break them, but other raiders will path around if it would be faster.

=Material choice

Wall materials each have their own advantages and disadvantages:

Wood Wood is easily obtainable in a vast majority of biomes, and are the fastest wall to create. They are very helpful when first starting a Crashlanded scenario, and nearly essential for Lost Tribe and Naked Brutality starts. However, wood is flammable. Other than raiders lighting it on fire, a bad dry thunderstorm or conduit explosion could end up engulfing your entire base in flames. Especially by the time you get to using Electricity, you should replace wood with another material.

Stone Stone is very plentiful, but very time consuming. In addition to actually creating the wall, cutting up stone blocks takes quite a bit of work. However, stone is a fairly hardy material, and is completely fire-proof. Strategically placed sections of stone walls will act as a "fire break" to limit the spread of a fire while your colonists fight it.

Granite is the most durable wall material. Limestone is the 2nd most durable. Limestone and slate have no redeeming qualities as walls over granite, unless your biome happens to lack the harder stone.
Marble walls give +1 beauty to a room and colonists looking at it. They are otherwise the least durable stone wall.
Sandstone walls are the quickest stone wall to build, which can save a lot of time for large bases.

Metal Steel isn't as durable as stone, but is much quicker to make. Steel may be a necessity in wood-scare biomes like the ice sheet. Steel walls are also flammable, unlike concrete and the actual steel item. Overall, it's useful as a quick installation when creating defensive fortifications.

Plasteel and Uranium are even bulkier than stone, but these materials shouldn't be wasted except on the most important of wall sections, like the entrance of a killbox.

Gold and Jade walls are more beautiful than regular walls, but are inferior to sculptures when increasing room stats.

Version history

0.7.581 - Wood wall and metal wall merged into wall with the introduction of the stuff system.
1.1.0 - Terrain requirements now depends on what they’re built from. This means stone walls can’t be built on bridges any more.
1.1.2654 - Increase psyfocus gain of wall from 11 to 22.
1.3.3200 - thump damage multiplier versus walls reduced from 4x to 2x.
