A biome is a particular section of the world with a specific climate, home to particular mobs and containing particular resources. There are currently five biomes in starve.io: the forest, the winter, the ocean, the lava biome and the desert. The forest biome was the inaugural biome, the place where you spawn at the beginning of the game. Afterwards, the winter was added in the "WINTER IS FINALLY HERE" update, located next to the forest. The next biome, known as the ocean, is a large body of water, which contains small islands, the only places where treasure chests can be found. The ocean biome is located all around the islands, and was added in the "VAMOS A LA PLAYA" update. The lava biome is located on the another island, and was added in the "It smells like burning!" update. The new desert biome was added in the "Desert" update.
Players start out in the forest biome, and generally move to biomes that are more dangerous but contain better loot (such as the winter, ocean, lava and desert biomes) as they progress. Mobs spawning and cold/heat are based on the biome they are in.
The Forest is the original biome that encompassed all of the map when the game came out. Currently, it covers about 1/5 of the map and takes up half of the bottom section, accompanied by the ocean. The forest is the basis for survival, as it has a much warmer climate than other biomes, as well as less powerful mobs. All players spawn in the forest, and work their way towards the winter and/or the ocean.
The forest is advantageous for players because of its warmer climate. It also provides players with basic resources and food required for survival. The forest is the only biome that allows players to plant berries, wheat, pumpkin, wheat, and garlic without first placing down a plant plot and/or bridge (excluding islands in the ocean). Players are also able to move faster in the forest then in the winter and ocean. Ground / soil can be exclusively gathered in the forest, using a shovel.
The forest can be disadvantageous for players mainly due to the number of players there. There is competition for resources and points. For example, players may take berries or gather gold right when you were going to, leaving nothing for you. Also, aggressive players would attack, chase, and possibly kill you so that they can have resources all to themselves, or simply because they want your points so they can get in the leaderboard or want to get items from your box after you die. If you want to avoid that, try going on servers with fewer people. Be careful though, you may lag a lot and still be chased. Also, the forest does not give the higher tier resources of diamonds, amethysts, dragon hearts, and winter fur, etc. Not to mention it is fairly hard to get water without going to Lakes, which are usually camped by other players.
Winter is a biome that was added in the "WINTER IS FINALLY HERE" update. It covers 1/5 of the map and is above the forest. The winter has 2 tree borders, one facing the eastern ocean with a small break for you to get to Lava faster; and one border covers the western border. The winter is the coldest biome in starve.io. It is almost impossible to stay alive without using any warming items such as Chapkas or Fires. The winter is the higher stage for advanced players to obtain high tier resources, such as Diamond, Amethyst, Dragon Heart and Mammoth Fur.
Fun Fact: the nametag turns dark blue when a player goes into the winter.
The advantage of the winter is that there are fewer players and bases than the forest, and players can focus on survival. Also, the winter contains more powerful resources which increase the player's power. You can get resources more easily there due to how large the biome is, and because of the lack of players. You will also be able to obtain resources where you cannot find anywhere else, such as diamond, amethyst, winter fur, and dragon hearts. (Amethyst and diamonds can be found in the Arctic biome's cave, dragon hearts can be obtained by killing the dragons that live in the cave, and diamonds can also be found). If you wear a mammoth fur coat, you lose about 9% of you're temperature as a human.
The winter is extremely cold and has mobs that are challenging to kill without the right technique and equipment. Also there is no naturally spawning plants so a player would have to bring one over along with a plant plot in order to be able to plant anything. Since it is very cold it is very hard to survive without a coat and you will have to put down many campfires to keep warm and survive, as well as have a large amount of food in your inventory.
The player movement speed is reduced by 20% here, due to the snow and so it would be hard to kill animals in the winter biome.
The cave is located in the top left edge of the winter biome. The cave is guarded by over 5 dragons. Amethyst and Dragon Heart resources can be obtained in the cave.The player would have to avoid being killed by the dragons in the cave. Most players block off the dragons by using walls and hit the dragons through the wall by using a spear. When they don't intend to kill any dragons, they use an explorer's hat to get to the amethyst (dragons can still attack if you hit them though).
Even with a coat, the heat loss is about as much as wearing nothing during the night in the forest. Also, the polar bear and the arctic fox have a lot of HP and are very dangerous, as the biome is in general. Make lots of campfires, full gold tools, and try not to die!
In the winter there are supplies of every deposit that currently exists, except for Reidite. It should be noted that most trees inside of the Winter Biome will only give about 25-40 wood each, so it is a good idea to get as much wood as you can beforehand to make fires instead of relying on trees inside of the winter.
If there is no inventory space prior to entering the winter to hold extra gold for making diamond tools, there are large amounts available inside of the center of the biome to mine.
The only way to obtain food inside of the winter is by killing arctic foxes and polar bears for meat, but this is not recommended for inexperienced players who don't know how to kill them. A good idea to make sure that you have enough food for an expedition is to set up a farm in the forest for berries, and obtain at least 200-300 of them.
The ocean is a biome added in the Vamos a la Playa updates. The ocean occupies around 1/5 of the map. In the ocean, the thirst bar will fill, but the cold bar will decrease faster, and you also lose oxygen. The same effects also occur to the player in the lake and river.
The border between the biomes and the ocean is the beach, the crabs' home and where sand can be gathered infinitely, using any type of shovel.
It's recommended that you bring bridges with you when going in the ocean, because otherwise, you can easily drown, freeze to death or be killed by mobs, which are faster than you in water. Also, most players use the islands to travel across the ocean (unless if they have access to bridges). It is certainly possible to travel in the ocean without advanced equipment, but obtaining some sort of diving gear will help you travel faster in the water, and reduce oxygen loss.
Plus it is also possible to get stone/gold/diamond/amethyst from digging sand in the beach., the chance to dig minerals can increase if you use the higher tier of shovel or wearing a Crown of Luck.
The Lava Biome is the biome introduced in the 'smells like burning' Update. The lava biome is located at the top right, convering roughly 1/5 of the map. In the lava biome your cold bar becomes a heat bar, which if reaches the max heat level, will start draining your health. To keep your heat bar low, you need to eat ice, which brings your heat bar down. It is home to the Lava Monster and the Lava Dragon. If you kill a Lava Dragon within 8 days of spawning you will get the Lava Orb, which can be used to make the Lava Sword/Lava Spear. There also is the second rarest ore currently in the game - Reidite Ore. There are lava pools in which if you go, you will immediately start losing health.
Try eating ice cubes as soon as your heat bar is full, so you waste as little as possible (but if you need to regen then eat more)
Depending on the time you will spend there, its good to get 300-500 ice with you (for water bottles. Also wearing anything that warms you (chapkas, hoods, tunics) will make your bar go up much faster, so don't forget to equip them off
If aggressive players attack you, try going around deposits and blocking them with walls, while gathering ice, then go to the lava biome and try eating as little ice as possible
Lava Monsters are about the same speed as you when not holding weapons. When you hold a weapon they are faster than you, so be careful with killing them
Its much, MUCH easier to get amethyst in the lava biome, since you don't have to fight many dragons to get it (unless you are 'lucky' and find the Lava Dragon)
If you have protection, wear it. It will prevent you from gaining any more heat.
If you want Reidite, you will have to go to the Reidite "cave" in the corner of the map. This cave is slightly smaller than the cave in the arctic. You should place Reidite doors to protect yourself, as Lava Monsters and Lava Dragons can't break reidite structures. Remember to leave the doors open when you leave, everyone hates cave-blockers.
The desert is biome added in the "Desert" update. The Desert is currently in the southeast corner of the map, roughly covering 1/5 of the map. The desert temperature is a big threat to the player 24/7. The day is very hot and the night is very cold, also a random sandstorm may happen. The sandstorm will do damage to players rapidly and can easily kill you. The only way to protect yourself from it is by wearing a Desert Hat (Cap and Turban) or hiding under a Roof.
The desert contains two new enemies; The vulture and sandworm. The vulture is basically like a naturally aggressive hawk and the sandworm is a mob that chases the player underneath the sand and only can be hit when above the ground. The sandworm can also destroy structures.
The desert is hot in the day and cold in the night. Just by this, make sure you have some sort of fire source/chapka/hat and ice/heat protection. Also, a sandstorm may happen at any given time, so make sure you have some roof/turban/cap.
