Decayed is a primary biome characterized by its burnt, post-apocalyptic look and urban garbage. It has dry weather, warm temperatures, little or no trees, and no other plant life. Decayed planets are notable by having ruined cities in the background suggesting that the planets were once populated and may still have some inhabitants. Decayed planets are a 'inconceivable' threat level, geared towards tier 6 in progression.

Scorched biomes (similar to Decayed biomes but without the city in the background) can be created and expanded using a Scorched Terraformer, and a planet will convert to a Decayed planet once half of the planet's surface has been terraformed into Scorched biome.

Decayed planets can only be found orbiting fiery (red) star types. Unless players have a Cooling EPP Upgrade equipped they'll take increasing damage while on the surface from deadly heat.

Navigation Console

Decayed planets can be identified by the keyword scorched in their navigation console description.

  • The landing location is a scorched wasteland. The atmospheric temperature is dangerously high. It is impressively brave of you to consider this destination.
  • The beam site is scorched and desolate. Little is capable of surviving here as the temperature is fatally high. People live in the area, but I cannot fathom why.
  • The landing site is scorched by the intense heat of the planet's surface. Only a few hardy individuals remain, possibly out of pure habit.


The surface layer of decayed planets is primarily made up of Dry Sand, Dry Dirt, Cobblestone, Stone Rubble, and Junk Pile.

All late-game ores are found in decayed biomes, with coal and copper available near the surface.

The surface of the ground is mostly covered in dirt and junk, and the topography is often hilly with small subterranean caves.

Sub Biomes

Decayed is a planetary biome with dry conditions and abundant Wooden Telephone Poles and Wooden Utility Poles. Volcanic and Midnight biomes have a chance to appear as smaller biomes on decayed planets. Watch out for the landmines and explosive barrels that litter the surface.

Decayed biomes can be found as a sub-biome on Tundra and Volcanic planets.

Mini Biomes

Decayed biomes do not have any mini-biomes of their own, but decayed planets can have sub-biomes of Volcanic and Midnight which in turn can provide their own mini-biomes.


Decayed planets stick to the standards for planetary layer composition.

  • Space: Asteroids
  • Atmosphere: Atmosphere
  • Surface: Decayed (Primary Biome); Volcanic, Midnight (Secondary Biomes)
  • Subsurface: Underground 0a, Underground 0b, Underground 1a, or Underground 1b
  • Shallow Underground: Tarpit, Mushrooms, Wilderness, Mini Village, Underground 0a, Underground 0b, Underground 1a, or Underground 1b
  • Mid Underground: Luminous Caves, Stone Caves, Bone Caves, Ice Caves, Underground 0c, Underground 1c, Underground 1d, Underground 3a, Underground 3b, Underground 3c, or Underground 3d
  • Deep Underground: Cell Caves, Flesh Caves, Slime Caves, Underground 0d, Underground 5a, Underground 5b, Underground 5c, or Underground 5d
  • Core: Blaststone Core Layer, Magmarock Core Layer, or Obsidian Core Layer


Weather on decayed planets is mostly a perpetual storm of dust and loose junk with a chance of either sandstorms or a combination of meteor showers and large meteors. Each decayed planet has one of these two pools of weather, and it will not change. Decayed planets without a meteorite shower chance will never have meteor shower weather.

Weather happens for each planet based on the weights given to the weather types (probability is calculated by dividing a single weight by the sum of all weights); the probability for weather types on decayed planets is as follows:

Type 1
Junkstorm 0.98 (98%)
Sandstorm1.png Sandstorm 0.02 (2%)
Type 2
Junkstorm 0.86 (~95.6%)
Smallmeteorstorm.png Meteor Shower 0.03 (~3.3%)
Meteorstorm.png Large Meteor 0.01 (~1.1%)

Wild Crops

The only crop native to decayed biomes is Wartweed. These can be harvested by interacting with them or by digging them up. They'll drop produce and have a chance to drop a seed which can be replanted.


In addition to procedurally generated creatures, there are a variety of unique monsters, bugs and critters found in decayed biomes. Some of these are also found in other biomes, while others are unique only to decayed biomes. While these unique creatures have a chance to appear on decayed planets, they will not all appear on each one. In addition to unique creatures, each biome has multiple types of both procedural ground and flying creatures.

Unique monsters each have combat attacks, and they must first be weakened before capture. Once weakened players can attempt to capture using a capture pod. If successful they can then be released to battle alongside and follow the player.

Critters are smaller non-combat unique creatures which are not capturable using capture pods. They can be captured without weakening them first by using a relocator gun. After releasing a critter from the relocator it will stay in the area it was released into.

Bugs are very small unique creatures which can be captured using a bug net, and are then stored inside placeable jars. Bugs which are captured using a relocator will fly after release instead of being kept inside a jar.

Unique Drops

There are a variety of items which are specific to chests found in decayed biomes. Some of these may have a chance of being found in other places throughout the universe, but they've all been specifically allocated to chests within decayed biomes.

Decayed Chest is unique to this biome, and has a number of unique drops allocated to it.

Decayed biomes have a chance to have most settlement types appear. There aren't any settlement types which are more likely to be found on decayed planets.



  • A group of electric poles with a cluster of storage containers and explosive barrels nearby
  • Scorched city ruins consisting of 1 to 2 towers roughly 2 to 3 floors in height
  • Underground shelters filled with crates and storage lockers. Some shelters are buried and contain chests. However, these buried shelters are often booby-trapped with explosives
  • The remnants of an old road system. Digging underneath the road may sometimes reveal chests
  • The scorched and burnt remains of shops or other single story buildings
  • The burnt-out and partially destroyed remains of city towers. Watch out for explosive barrels and wall-mounted explosives. If you find a building filled with junk blocks look for a chest nearby or dig through the junk to find it
  • Observation towers containing 1 to 2 enemy NPCs
  • Underground tunnels with a treasure chest at the end. The tunnels are booby-trapped with explosives but the chest contains valuable treasure
  • Elevated platforms with storage containers. Beware of land mines
