A biome is a particular section of the world with a specific climate, home to particular mobs and containing particular resources. There are currently four biomes in starve.io: the forest, the winter/snow, the ocean, and the lava biome. The forest biome was the inaugural biome, and is currently located on the bottom left side of the map. Afterwards, the winter was added in the WINTER IS FINALLY HERE update, located on the top left half of the map. The next biome, known as the ocean, is a large body of water, which contains six small islands, the only places where treasure chests can be found. The ocean biome is located in the bottom right part of the map and was added in the VAMOS A LA PLAYA update. The new lava biome is located in the top right and added in the It smells like burning! 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, and lava biomes) as they progress. Mob spawns 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 1/4 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 amount 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 less 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 a Lake, which is usually camped by other players.
The winter is a biome that was added in the WINTER IS FINALLY HERE update. It covers 1/4 of the map and is larger than the forest and ocean. The winter is much colder than the forest, and it is almost impossible to stay alive without using a chapka or fires. The winter is the stage for advanced players to obtain high tier resources, such as amethyst and the dragon heart.
Fun Fact: the nametag turns 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 increases 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 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).
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.
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 the new biome added in the Vamos a la Playa (Spanish for "Let's go to the beach", and it is also a song) update.
The ocean is a biome added in the Vamos a la Playa update. The ocean occupies the lower right quadrant of the map. In the ocean, the thirst bar will fill, but the cold bar will decrease faster, and also lose oxygen. The same effects also occur to the player in the lake.
The border between the forest and the ocean is a 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. Some players actually use the ocean to easily get to the diamond deposits in the winter, as there is a small opening between it and the ocean.
The Lava Biome is the newest biome introduced in the 'smells like burning' Update. The lava biome is located at the top right, convering roughly a quarter of the world. It is only accessible through a gap in the coastal trees or by going through the arctic.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 red dragon within 8 days of spawning you will get the red dragon orb, which can be used to make the red dragon sword/spear. There also is the 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
Try getting lots of winter mobs near the winter-lava border, go into the lava biome and stay to the border while moving up or down and staying close to the border, this way the mobs wont hurt you and you will finish them fast and get food easily
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 (i wrote how to eat in the 1st tip).
Lava monsters are about as the same speed as you when not holding weapons,when you hold one they are faster than you, so be careful with killing them (as with the winter mobs, get them on the border and kill 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)
diamonds are better to be gathered in winter (around the cave, not inside).
If you have protection, wear it. It will prevent you from gaining any more heat.
If you want reddite, you will have to go through the reddite cave. This is bigger than the amethyst cave in the arctic. You should place gold doors or better to trap the red dragons. Do not stand in the lava.
