Overworld biomes

The ◯Overworld on Sunday Market has roughly 3x as many biomes as vanilla. Some are vanilla biomes with denser vegetation or richer textures. Many are entirely new — biomes you've never seen before, with custom blocks, mobs, and atmosphere.

Walking in any direction from spawn for an hour will take you through 5–10 distinct biome types. The terrain is more dramatic than vanilla — taller mountains, deeper valleys, more dramatic cliffs.

What's there

Vanilla biomes (deepened)

Forests, deserts, plains, mountains, swamps, jungles, taigas, savannas, oceans, beaches — all present. Many are more vegetated, more varied, or more dramatic than vanilla:

• Forests are denser, with more shrub variety
• Deserts have more terrain variation (canyons, oases, dunes)
• Mountains are taller and more dramatic, often with new biome variants at altitude
• Oceans have varied seabeds and tidal-like surface effects
• Swamps are denser and feel genuinely overgrown

New overworld biomes

Many biomes are new entirely. Highlights you'll find while exploring:

• Mediterranean-style scrub and olive groves
• Bog and fen wetlands with thick mist
• Highland steppes at elevation
• Bamboo forests beyond the vanilla bamboo jungle
• Cherry groves in spring-themed pink-petal biomes
• Eucalyptus forests with new wood types
• Volcanic and lavafield biomes
• Crystal caverns within mountain interiors
• Towering pines taller than vanilla spruce
• Coral coast themed beaches
• Salt flats and alkali deserts
• Glacial and arctic biomes
• Sandstone canyons with deep-cut river systems
• And dozens more — discovery is the point

Reworked terrain

Beyond biomes, the terrain itself is reshaped by a tectonic-style generator:

• Mountains can be 3–4x taller than vanilla, with proper rocky peaks
• Valleys are deeper and more pronounced
• Cliffs and overhangs are more common
• Rivers carve through terrain dynamically
• Islands in oceans are more varied and frequent

The result feels like a real continent, not flat-with-occasional-hills.

What hasn't changed

• Spawn rates for vanilla mobs are roughly vanilla
• Vanilla structures (villages, dungeons, ocean monuments, etc.) still spawn (alongside the new ones)
• Block IDs are vanilla-compatible — bedrock is bedrock, dirt is dirt
• Biome dimensions still respect vanilla rules (X/Z, no per-Y biomes outside vanilla cave biomes)

Common destinations worth seeking

For builders

• Cherry groves and pink-petal biomes — pink wood and pretty terrain for themed builds
• Mediterranean scrub — olive-tree decor and warm color palette
• Highland mountains — elevation drama for fortress builds
• Coral coast — turquoise water for beach builds

For explorers

• Volcanic biomes — visually striking, often near rare ore
• Crystal caverns — interior of certain mountain biomes
• Glacial biomes — for the contrast and the rare ice-themed loot

For resource gatherers

• Bamboo forests — for bamboo building blocks
• Towering pines — wood by the truckload
• Mediterranean scrub — olive wood, scrub planting

How to explore efficiently

Walk first, build later

Don't commit to a base in the first 500 blocks from spawn. Walk for 10–20 minutes in a direction. Check 3–4 biomes. Then decide.

Bring a map

Vanilla maps work; you can also use the in-game /profile and exploration tracking to see what you've discovered. Maps fill in as you walk.

Pearl arc for terrain scanning

Throw a pearl at high arc to land 50+ blocks away. Lets you "scout" terrain before walking through.

Bedrock has full overworld biome support

Both Java and Bedrock players see the same biomes. The custom biomes render natively in both editions.

Underground

Cave generation is also custom — caves are larger, deeper, and more varied than vanilla. Underground biomes (lush caves, dripstone, deep dark) are present, sometimes more elaborate than vanilla. Underground rivers and lakes are common.

Mining straight down still works as a strategy, but exploring caves is rewarded — they connect to surprising places.
