Tundra Biome

Tundra Biome is a cold, breathable-surface biome that commonly contains large deposits of ice, snow, and cold-friendly flora. It appears in at least two variants: the Base Version, which ranges from approximately -183 °C to -16.15 °C, and the Swampy Asteroid variant, which ranges from roughly -30 °C to -16.15 °C. The extreme cold can allow liquid carbon dioxide to appear naturally where temperatures are low enough.

The biome is notable for abundant ice and snow tiles; melting these tiles rather than mining them yields twice the water compared to mining the ice and then melting it. Because of the extensive ice, the Tundra makes an effective early heat sink: channeling excess heat into the biome can delay overheating problems during industrial expansion. Care must be taken, however, since raising local temperatures or venting waste heat into the biome will disrupt Sleet Wheat and other cold-dependent plants.

Sleet Wheat is a common and valuable plant in the Tundra Biome. It serves as an excellent late-game food source when cultivated properly. Wheezeworts also occur here and provide passive cooling; they are an effective, low-power alternative to an Aquatuner + Steam Turbine setup for many early- and mid-game refrigeration needs. According to in-game observations, Wheezeworts in this biome also produce a significant amount of radiation and can be exploited as a relatively simple early source for Applied Sciences research.

Points of interest and typical resources found in the Tundra Biome include:

• Anti Entropy Thermo-Nullifier structures located in some maps.
• Various Ruins that can contain loot or hazards.
• Two random buried cold geysers in many seeds, providing renewable cold and potential liquid emissions depending on the geyser type.
• Large expanses of ice and snow that can be harvested or melted for water.

Practical notes for using the Tundra Biome:

• Use direct melting of ice/snow patches to maximize water yield and reduce resource waste.
• Employ Wheezeworts for localized, low-technology cooling; they reduce the demand for power-hungry cooling systems early on.
• Treat the biome as a heat sink for excess industrial heat, but avoid permanently warming key Sleet Wheat farms if you intend to harvest them long-term.
• Watch for localized pockets of liquid CO2 in the coldest spots; they can be both a hazard and a resource depending on your setup.
• Explore ruins and thermo-nullifier sites cautiously; they can contain useful items but also environmental dangers typical of ruined structures.

The Tundra Biome is balanced between utility and fragility: it grants easy access to water and passive cooling while demanding careful thermal management to preserve its crop and plant-based advantages.
