Planet Biome & Environment Effects Guide - How Worlds Change Your Play

Your first planet pick determines whether you thrive or struggle through the first 20 hours.

Want the short version? Prioritize temperate worlds for new players, desert planets when you have reliable solar, and avoid lava or toxic biomes until you have reactor cooling and life support researched. Ice worlds are a trap unless you know exactly what you are signing up for.

Biome Priority Quick List

If you are rushing the tech tree, a temperate start into a gas giant moon colony is the smoothest mid-game transition. Read the Mid-Game Expansion Strategy guide for timings.

Environment Effects Breakdown

Temperature

Every biome has a baseline ambient temperature. Your reactor and industrial buildings generate heat on top of that. If ambient temp pushes the combined total past your cooler’s capacity, production slows or buildings take damage.

Temperate and desert worlds are forgiving here. Ice worlds require pre-heated coolant loops before reactors even start. Lava worlds demand mk3 coolers or liquid coolant piped from off-world – expect a major power tax.

Gravity

Gravity directly multiplies the fuel cost of every cargo launch. A gas giant moon at 0.4g means your rockets cost less than half what they do on a standard temperate world. This matters enormously when you are shipping refined materials between colonies.

The corollary: high-gravity worlds like lava (1.3g) are terrible places to export from. Build refineries there, process locally, and only ship out the high-value finished goods.

Solar Efficiency

This is the stat most players underestimate. Solar panels produce power proportional to the biome’s solar efficiency percentage. On a desert world (140%), one panel does the work of almost one and a half. On toxic (5%) or lava (25%), solar is a waste of materials.

This is where I made my biggest mistake. I built my second colony on a lava world thinking the abundance of volcanic minerals would offset the power cost. My solar farm produced 25% of expected output. I had to ship in fuel cells by rocket for 10 hours before I unlocked geothermal. Do not skip the solar check.

Life Support Requirements

Biomes dictate what your colonists need to survive, which translates directly to production chains and power overhead.

Temperate and Desert: Standard atmosphere processors, basic water recyclers. Nothing special. These biomes forgive mistakes.

Toxic: Every hab module must be sealed. Unsealed airlocks cause atmosphere contamination. You need double the filtration capacity. This adds about 40% to early colony power draw.

Ice: Oxygen is plentiful from ice cracking, but heating every hab module drains power. Budget 30% extra power for hab thermal management.

Lava: Cooling, not heating, is the problem. Hab cooling loops require advanced coolant or frequent maintenance. Expect to replace coolant pumps twice as often.

Gas Giant Moons: Thin atmosphere means lower pressure habs are acceptable, but radiation shielding becomes a concern. Research atmosphere capture early – it pays for the colony itself.

When to Expand

The research tree gates the biome you can settle next. The Deep-Space Gas Giant Mining guide covers the exact tech requirements for moon colonies, but here is the rough roadmap:

• Early game (first 2 planets): Temperate only. Do not try desert until you have mk2 solar.
• Mid game (3-5 planets): Desert and gas giant moons. Unlock geothermal before lava.
• Late game (6+ planets): Everything is viable if you have the right modules researched.
