The Rock Bottom demo is free on Steam under the same AppID as the full game (4297840). It is currently active and covers three biomes: Sunken Canopy, Spore-Light Caverns, and Static Peaks. Install it from the official Steam store page, not from a third-party link. The full release on July 14, 2026 adds five more biomes and the Foundry alloy system that the demo does not include.

How to Install the Rock Bottom Demo

The install path is the standard Steam flow. There is no separate installer, no third-party launcher, and no purchase required.

  1. Open the Rock Bottom store page on Steam in the Steam client or in a browser.
  2. Find the demo entry. Steam surfaces demos as a separate "Download" or "Play Demo" button on the right rail, distinct from the full-game purchase button.
  3. Click the demo button and confirm the install. The demo downloads into the same Steam library as the full game.
  4. Launch the demo from your library. The first launch uses Steam's default 1080p Windowed Mode after the Jan 31 hotfix, which addressed 4K Fullscreen compatibility on first run.

If the demo entry is not visible, the user is likely on a localized Steam region where the demo is hidden. In that case, check the release status page for the live status.

What the Demo Covers: Three Biomes

The Steam Community Dev Blog lists three named demo biomes, and the in-game UI uses the same labels. Together they cover the swing-to-smelt rhythm, the early skill tree picks, and the first difficulty jump.

  • Sunken Canopy. The first demo biome. Overgrown vines and flowers, a green "breather" area, and a focus on gold ore. This is where the player learns to swing, mine, and start smelting.
  • Spore-Light Caverns. A darker, more dangerous layer lit by neon fungi. The primary ore is cobalt, and the visual contrast is blue light against dark stone.
  • Static Peaks. The hardest demo biome. Rainy, noisy, with gravity wells and static discharge hazards. Ores include iron and gold.

All three biomes feed the same permanent skill tree, so upgrades picked in Sunken Canopy remain in effect when the player pushes into Static Peaks. The demo stops there; the next four layers and Crystal Caverns are post-demo content.

Demo vs Full Release: What Is Missing

The demo is a slice, not a shortcut to the full game. The full release on July 14, 2026 will ship eight layers in total, so the demo only covers three of them. The full release also adds the Foundry, an alloy-crafting system previewed in the Dev Blog that combines two different bars into new resources. Players who finish the demo and want the rest should buy the full game from the Steam buy page on or after the planned release date. The biome reference lists the full eight-layer roadmap, and the homepage hosts the first-week play plan that chains the demo to the full release.

Known Demo Patch Notes

Two official demo patches are on record in the Steam Community Hub:

  • Demo Hotfix (Jan 31). Default launch mode set to 1080p Windowed for better first-run monitor compatibility; fixed fullscreen toggle; fixed a tutorial progression bug.
  • Demo Hotfix 2 (Feb 2). Click-to-select level buttons, hover tooltips for resources, muted dialogue blips, and a jetpack rework that uses its own fuel gauge.
