About This Demo

Change the landscape. See what follows.

Raise mountains, lower terrain, and shape ridges and valleys in Terra Logic, a planetary terrain and environment sandbox. Watch water, climate and vegetation respond as simulation time advances. This demo includes modern Earth and two selected experiments.

Your part of the Earth

Terrain editing is available between Gibraltar and the Himalaya: 5°–50°N, 12°W–100°E. You can observe the rest of Earth, but cannot edit it in this demo. Both included experiments are inside the editable region.

One Stroke for Everest

Lower Mount Everest below the target elevation, learn the terrain tools, and follow the effects of changing a mountain. Plan your strokes within the experiment's engineering allowance.

Qattara: A Desert Coastline

Connect the Mediterranean to the Qattara Depression while keeping high ground near Alexandria dry. Where you dig, how much material you move, and whether water can reach the basin all matter.

Keep experimenting

Continue shaping the permitted region in the modern Earth sandbox. Save, load, undo and retry freely, with no overall play-time limit. Each experiment retains its own objectives, engineering allowance and simulated-time scoring. The sandbox has no engineering-volume cap.

What this demo includes

Modern Earth and the two experiments are playable. Other scenario and campaign entries are previews. Other playable worlds and eras, blank planets, flat canvases, heightmap import, Minecraft Java export, the scenario editor and Steam Workshop belong to the full game and are not included in this demo. The interface supports English, Simplified and Traditional Chinese, Japanese, Korean, French and German.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

During development, AI tools helped create achievement icons and portions of the in-game text, translations, and store descriptions. Whisper displays short on-screen text without voice acting. It selects and combines bundled text locally in response to simulation events, geography, and historical references. Whisper does not require an internet connection, API key, or model download. The game does not use generative AI services or local large language models during gameplay.
