The Tundra Expanse

Lore & Background

In the world of Planet Zoo, the Tundra Expanse is presented as a vast, open biome defined by its extreme cold and minimal vegetation. Unlike the lush rainforests or the golden savannas, the tundra palette is dominated by whites, pale blues, and muted earth tones broken by the dark basalt of outcropping rock. Snow covers the ground in seasonal drifts, small frozen pools and streams thread through the terrain, and the horizon stretches wide and unbroken—a deliberate design choice that gives the biome a sense of isolation and scale.

The animals that call this region home reflect that harshness. Polar bears patrol the icy shorelines, their massive frames built for hunting seals at the water's edge. Smaller creatures like the Arctic fox and Arctic hare rely on seasonal camouflage, their fur shifting between white and brown as the tundra cycles through its brief growing season. Above it all, the snowy owl glides in silent arcs, a ghost against the overcast sky.

For the player, the Tundra Expanse is as much a design challenge as a visual one. Keeping these animals warm, providing appropriate enrichment, and ensuring their enclosures feel like a natural extension of the frozen landscape rather than a glass box is central to the game's welfare system. The biome rewards players who understand that cold-climate animals need open space, shelter from wind, and access to water that doesn't freeze solid—details that make the tundra one of the more thoughtful and atmospheric biomes to build within.

Reader's Guide

The Tundra Expanse is a cold-climate biome in Planet Zoo that players can select when designing their zoo's layout. It features a snow-and-ice terrain palette, sparse tundra vegetation, glacial rock assets, and frozen water features that give it a stark, open atmosphere distinct from the game's warmer biomes.

When building in the tundra, the available animal roster shifts to cold-adapted species. Key residents include the polar bear, musk ox, Arctic fox, Arctic hare, snowy owl, walrus, and narwhal. Each has specific enclosure requirements: the polar bear needs access to water and space for swimming, the musk ox benefits from sheltered areas and social grouping, and the smaller mammals need hiding spots and appropriate ground cover.

Terrain tools in the tundra biome include snow-covered ground textures, ice patches, frozen ponds, and rocky outcroppings. Decorative assets lean into the cold aesthetic—bare stumps, driftwood, and low tundra shrubs. Players should pay attention to the animal welfare system, as cold-climate species have specific needs around temperature, enrichment, and enclosure size that differ from tropical or savanna animals.

The tundra works well as a visually distinct section of a larger zoo, creating a natural transition zone between warmer biomes. Its open, pale palette contrasts sharply with the dense greens of a rainforest or the golds of a savanna, giving players a strong visual anchor for their layout.
