An Evil Biome is a naturally spreading, hazardous biome that has generally negative effects on entities inside or around it. The Corruption or The Crimson will always spawn in a world. A generated world will only contain one of the two biomes, each with a 50/50 chance. A player can choose whether they want Corruption or Crimson to generate in their world or they can leave it up to the 50/50 setting. However, on the 主机版 a player has a choice only if Hardmode has been entered in at least one world.

It is possible to create an artificial Corruption/Crimson, seeding an area with the "wrong" evil. This is traditionally done with materials brought over from another world, but 1.4 provides a new option: If the Dryad is housed in a Graveyard during Hardmode, she will sell the other evil's Seeds during a Blood Moon.
Note: The type of Biome Key / 生物群落钥匙模具 dropped by enemies is dependent on the biome the enemy is killed in, regardless of whether it is a "natural" biome or "artificial" biome. This will not however provide a Dungeon chest to go with the key.
The following items are considered counterparts to each other. It should be noted that counterparts do not necessarily share the same stats or behaviors.

The Corruption presents a purple "corrupted" theme, with purple grass, trees and stone. Thorny Bushes and unique enemies (beginning with Eaters of Souls and Devourers) make the area dangerous and potentially deadly for newer players. The Eater of Worlds can only be summoned in the corruption. The Corruption contains deep vertical chasms (which can easily result in death from fall damage), with cross tunnels well below ground. Shadow Orbs appear deep underground, usually at or near the bottom of chasms. Destroying a world's first shadow orb will always drop a Musket and some Musket Balls, which automatically fulfills the criteria for the Arms Dealer to arrive. Destroying 3 shadow orbs will result in the spawning of the Eater of Worlds.
These music tracks play while the player is in the Corruption or Underground Corruption. Like most other tracks, they can be recorded with Music Boxes. On the 电脑版, when Otherworldly music is enabled, tracks from Terraria: Otherworld will play instead.
|Its melody somewhat resembles the Overworld Day track but altered and slowed to sound much darker and more menacing.|
|Underground Corruption||Music Box
|This track is a combination of Corruption and Underground tracks, with a depressing and dark tone.|
|Corruption (Otherworldly)||Otherworldly Music Box
|It's a dark, undulating track which features downtempo rock music.|
|Underground Corruption (Otherworldly)||Otherworldly Music Box
|Resembles its Otherworld surface counterpart, but is somewhat more aggressive.|
In contrast to the Corruption, the Crimson presents more of a red, gory theme, with red grass, stone, and foliage. Unique enemies that only appear on a crimson world include Blood Crawlers, Face Monsters and Crimeras. The Brain of Cthulhu, the alternative to the Eater of Worlds, can only be summoned in the crimson. Crimson-infected stone is called crimstone, and like its corruption counterpart, can only be mined with a Nightmare Pickaxe/Deathbringer Pickaxe or better. Like the corruption, the crimson contains deep chasms, but these are differently shaped: A winding tunnel from the surface leads to a large cavern, with secondary tunnels spreading downward from the cavern.These tunnels look quite like hands. While long falls are less of a hazard here, the area is still quite dangerous. Instead of Shadow Orbs, the Crimson contains Crimson Hearts, placed at or beyond the end of the secondary tunnels. Destroying a world's first crimson heart will drop The Undertaker with some Musket Balls, which, like their Corruption counterparts will fulfill the criteria for the Arms Dealer to arrive. Destroying 3 Crimson Hearts will result in the spawning of the Brain of Cthulhu.

|An unnerving, dark, and unsettling theme with a faster pace than that of the Corruption. Its main melody comes near the end of the track.|
|Underground Crimson||Music Box
|A grim mix of the Underground and Crimson tracks.|
|Crimson (Otherworldly)||Otherworldly Music Box
|A dark, ambient track which seems to feature some type of contrabass brass instrument for a 'gloomy' feeling and eventually becomes almost psychedelic-sounding.|
|Underground Crimson (Otherworldly)||Music Box
(Otherworldly Underground Crimson)
|A brooding and increasingly frantic track.|
Both the Corruption and the Crimson will spread themselves, similar to the Hallow. This means that they slowly convert certain susceptible tiles that are in the vicinity of existing Corrupt/Crimson blocks. While their spreading capabilities are very limited during pre-Hardmode, they spread much faster and more aggressively after defeating the Wall of Flesh. Defeating Plantera for the first time reduces the overall spread speed of all three biomes by 1/2 (50%).
The evil biomes can overlap deserts, and in Hardmode, can spread through them, creating Corrupted and Crimson deserts. In the Corruption, sand is replaced with Ebonsand, and in the Crimson, sand is replaced with Crimsand. Unique enemies not found in the normal Corruption and Crimson can be found in the biome's desert variant.
In Hardmode, the Corruption or Crimson (like the Hallow) can spread out of control; without player efforts, the evil biome and Hallow will together take over the entire world.
In Pre-Hardmode, players can use Purification Powder to purify small portions of the corruption/crimson, and Sunflowers to block spread of infected grass. However, it is not until Hardmode that the spreading biomes become a major issue.
In Hardmode, a good strategy is to dig 3 tile wide tunnels around the corruption/crimson, containing it. However, near the surface Thorny Bushes can spread the corruption up to 6 blocks, so the tunnels there need to be 6 tiles wide or lined with non-corruptible blocks.
Removing the Corruption or Crimson wholesale, or reversing its spread in Hardmode, effectively requires the Clentaminator. This can be purchased for
2000000*2 (one of the most expensive items in the game) from the Steampunker, who arrives after at least one mechanical boss has been defeated. Using the Clentaminator with Green Solution (also purchased from the Steampunker) can purify large sections of the evil biomes. However, most players will want to keep some well-contained pockets of the biome, as the enemies there have unique drops (some of which are recommended to advance in the game).
The evil biomes are also blocked by the presence of the Hallow, and vice versa; even before obtaining the Clentaminator, seeding the Hallow is an alternate strategy to limit the spread of Corruption or Crimson. However, this may mean eventually having to deal with an out of control Hallow in the future.
- 在 1.3中，世界生成的进度条有一半是绿的，另一半则是紫色或红色，取决于世界拥有的是腐化还是猩红。在世界生成过程中，生成猩红之地那一步会显示“正在使世界变得血腥”，而生成腐化之地时这一步显示的是“正在使世界变得邪恶”。另外，在世界选择界面上，世界名称旁边的树也有一面是绿色/正常的，而另一面是紫色/红色（分别代表腐化/猩红）。在困难模式中，树会有一部分是黄色，代表神圣。
