Terrain Regions
Current build first pass referring to logs list:
- Craters
- Hills
- Ground level This is similar related to Terrain
Biome/Layer System
The major biomes/layers will consist of soil/regolith, crust, mantle.
Different regions have different materials:
- Highland centers: Southern hemisphere, surface + exposed bedrock
- → Boulders, fragmented rocks
- → Ancient lake beds, segments at the bottom of highland craters
- → Clays and in bedrock at the rim
- → Sulfates, carbonates
Northern lowland centers: Northern hemisphere, younger, smoother flatter material → Dirt & sand plains → more soil
Polar ice caps: (at the poles) → soil, thick layers of ice + dust mixed together, joins games for materials
Canyons: → Exposed cliff faces, ore & raw minerals can be found
Plains/Lowlands: → Soil + fine dust cover → Undergrowth water ice at the subsurface (just for spawning) user does care [for] large scale snowfalls collector
CO2 clouds form primarily in the higher latitude areas & canyons, where the players will be spawning
Spiders from grosmith on the Southern hemisphere

Sketches
Two terrain view sketches showing:
- Crater terrain - ice at bottom, crater form view with boulders, elevated rim (labels: “Crater,” “Ice at bottom”)
- Plains/flat terrain - surface to default plains with track/path, zoomed-out isometric view
Mechanics Notes
→ Surface & default plains → Craters, spiders, etc will have dedicated + terrain + form configurations for each arena
(Cont over)
Different biomes will have different weather, uvs, etc
