Tundra is a planetary biome, signified by a cold, frozen plains. Not to be confused with the less dangerous Snow Planetary Biome, the surface of the biome proper is dotted with trees holding orbs of ice with their branches.
Tundra biomes can be created and expanded using an Icy Terraformer, and a planet will convert to a Tundra planet once half of the planet's surface has been terraformed into Tundra biome.
Tundra has quite a few similarities to the now-defunct Ice Mini Biome - it even uses Ice's Treasure pool rather than having its own Tundra treasure pool.
Snowmen and Fancy Snowmen can be found on the surface.
Tundra planets are most frequently found orbiting Frozen stars, though they can also be found orbiting Fiery stars as well. Natively-generated Tundra planets have an Extreme threat level and a planetary Tier of 5. Tundra planets are the favorite habitat of the Apex, and Apex villages and dungeons.
- Temperatures at the beam site are dangerously low. The area is frozen, and inhabited only by flora and fauna that are extremely resistant to the cold
- A frozen place, formed of ice - the permafrost runs deep here. Snow storms are common and temperatures are dangerously low.
- This dangerously cold landing site is frozen solid. High likelihood of accidental self-cryopreservation. Protect yourself from the cold.
Tundra biomes use the Day Tracks plus both Arctic Exploration tracks during the day and the Night Tracks during the night.

Tundra planets stick to the standards for planetary layer composition.
- Space: Asteroids
- Atmosphere: Atmosphere
- Surface: Tundra (Primary Biome); Garden, Forest, Snow, Midnight, Decayed (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 in tundra biomes is either snow, blizzard or clear. 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 tundra planets is as follows:
There are a variety of harvestable crops found in each biome. 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 tundra biomes. Some of these are also found in other biomes, while others are unique only to tundra biomes. While these unique creatures have a chance to appear on tundra 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.
Tundra planets are most likely to have Apex themed dungeons and villages.
