Biome

Game Worlds

## Description

A **Biome** is a part of the world of *7 Days to Die* with certain characteristics, such as climate, resources and types of zombies. There are five Biomes in 7 Days to Die, which differ vastly from each other. Some *Point of Interest* buildings are specific to a biome, whether many can appear on any type of "soil". This also extends to *City* areas which group together a number of *Point of Interest* buildings.

When a survivor is looking for a place to build a home/fort/base, they should consider the pros and cons of each biome, as these will determine the difficulty by zombie spawns and available resources. From *Alpha 17* it is also important to look out for clothing which can help alleviate negative effects of overheating in hot areas, as well as freezing in cold areas.

Different Biomes also affect the Player's Loot Stage differently, therefore tougher biomes tend to contain higher tier and quality loot. The exact numbers can be found in biomes.xml.

## Biome Types

There are currently five Biomes in Navezgane and four in Random World Generation. Burnt Forest is not present in Random World Generation.

Descriptions in square brackets show the first method (in many cases the best) of obtaining resources from the objects:

* punch - object can be punched and destroyed on hit, getting resources
* stone axe - punching requires a few hits and don't give resources with each hit, whether using stone axe destroys it on one hit, getting resources or allows gathering them from the object at a steady pace per 1-2 hits (for example trees or boulders)
* pickup - object can be picked up
* loot - object is a container and can be looted
* wrench - object can be wrenched for additional resources
* shovel - using a shovel allows fast gathering of the block, compared to stone axe or punching

**UNDERGROUND ORES:** As of Alpha 17 indication of underground ores have changed. Some are mostly abundant in specific biomes, although digging gravel patches gives a little of the same resource that is underground (breaking Boulders should also indicate similarly). Each biome can have any of the 4 ores indicated by the dug up gravel patch: Iron Ore, Lead Ore, Nitrate Powder, Lump of Coal. Snowy Forest is an exception with only Iron Ore and Lead Ore found, and Desert which lacks Lump of Coal, and instead has Oil Shale, which cannot be obtained from any other biome. An explanation to this can be (yet to be confirmed) that gravel patches show the dominant ore that is underground, where Boulders show all in their proportions (which constitutes from giving more resources when mined).

## Biome Guide Map

**Navezgane A16 and A17 Maps**

* A17 Map taken from: https://steamcommunity.com/sharedfiles/filedetails/?id=1569904615

**Map Legend**

As new players will be wondering which color represents each zone on the map until they encounter that zone, below is a list of coresponding colors to biome. The map on the left shows all these zone, the one on the right is A-17 as comparison for removed zones.

* White = Snow Biome
* Yellow = Desert Biome
* Lime = Wasteland Biome
* Green = Forest Biome
* *Brown = Burnt Forest Biome (unavailable in Random maps)*
* *Tan = Plains Biome [removed as zone]*
* *Red = Radiation Biome (removed as zone)*

## History

* As of Alpha 17 the number of biomes was reduced to five and not occurring will be marked accordingly. Radiation zones have been differentiated from biomes, making them not visible on the map. Additionally small radiation zones can be encountered inside the play area, not only closer to the map borders.
* As of Alpha 19, but possibly earlier, there are no pockets of radiation inside the play area.
* As of 20 the radiation zone is not a biome, rather a zone that simply extends from the edge of the map. The biome is one of the previously mentioned.
* As of Alpha 20 the Burnt Forest no longer generates as a part of Random gen maps. It is still present in Navezgane as of Alpha 20.2.
