Rock Bottom biomes are the eight unique layers that stack from the surface down to the title layer at Rock Bottom. The full release ships all eight; the free demo that is live on Steam today covers three (Sunken Canopy, Spore-Light Caverns, Static Peaks). Dev Blog #1 previews a fourth post-release biome called Crystal Caverns, with pink and purple amethyst-inspired visuals and a new crystal ore.

How Many Rock Bottom Biomes Are in the Game?

The Steam store page for Rock Bottom (AppID 4297840) describes a full release that descends through eight unique layers. Each layer is its own biome: a procedurally generated cave system with its own ore types, hazards, and visual identity. As of 2026-07-14, the developer has named three of those biomes explicitly inside the live demo, plus a fourth that is previewed in Dev Blog #1 as the next post-release stop on the player's journey.

  • Demo biomes (three, playable today on Steam): Sunken Canopy, Spore-Light Caverns, Static Peaks.
  • Post-release preview (one, not in the demo): Crystal Caverns.
  • Remaining biomes (four): Not announced by name as of 2026-07-14.

Players who clear the three demo biomes have reached the current edge of the playable list. The remaining four layers and the Crystal Caverns update will land on or after the planned July 14, 2026 release.

The Three Biomes in the Demo

Sunken Canopy

Sunken Canopy is the first designed layer in Rock Bottom and the gentlest entry point into the biome stack. Dev Blog #1 describes it as the place where players hunt for gold ore among overgrown vines and flowers. The green palette and softer hazards make it the right place to learn the swing-and-smelt rhythm before the game starts punishing missed swings.

Spore-Light Caverns

Spore-Light Caverns is the second demo biome. The Dev Blog describes it as a mystical and dangerous area where neon fungi cast blue light across the cave. The headline resource here is cobalt ore, which feeds the smelter and funds the skill tree alongside the gold that Sunken Canopy already produced. Players who only want to test whether the loop clicks should at least push through this layer.

Static Peaks

Static Peaks is the third demo biome and the hardest of the three. The Dev Blog frames it as a noisy, rainy level filled with gravity wells and static discharge hazards. Static Peaks drops both iron ore and gold ore, which gives players two resource streams to feed the smelter at once. Beating Static Peaks in the demo is the practical "I get the loop" milestone.

Crystal Caverns: The First Post-Release Biome

Crystal Caverns is the first biome previewed after the demo trio. Dev Blog #1 introduces it as the next stop on the player's journey and describes a pink and purple amethyst-inspired tile set filled with stalactites, stalagmites, and a pastel palette. The new resource is crystal ore, which is unique to this biome and will eventually feed the smelter alongside gold, cobalt, and iron.

As of 2026-07-14, Crystal Caverns is not in the day-one demo and is not in the planned July 14, 2026 launch build. It is previewed only in Dev Blog #1. A new Dev Blog post, a release-day patch note, or a Steam store update would change that status, and this page will be refreshed as soon as the developer confirms a date. The dedicated Crystal Caverns page covers that status in more detail.

The Four Unnamed Layers

The Steam store page confirms eight unique layers in the full release. Three are named in the demo, and a fourth (Crystal Caverns) is named in the Dev Blog. That leaves four layers that have not been publicly named as of 2026-07-14. The Dev Blog teases the next biome with the line "things really start heating up," which signals that later layers will introduce tougher hazards and hotter visuals, but no specific biome names or resources have been announced for them.

When the developer names the next layer, this page should be updated with the new theme, ore type, and availability status. Until then, treating the four unnamed layers as "not announced" is the only accurate answer.

What Evidence Would Change This List

  • A new Dev Blog entry that names additional biomes, theme, or ore types.
  • A Steam store update that lists all eight layers in the full game description.
  • A release-day patch note on July 14, 2026 that ships a new biome alongside the unlock.
  • A post-release roadmap that confirms the timing of Crystal Caverns and any later layers.

Until one of those updates lands, the four unnamed layers and the four named biomes stand as the current list.
