Yayo’s Planet Mod

Yayo’s Planet Mod Mod introduces recurring, extreme seasonal catastrophes that strike every in-game year during the 4th quarter, forcing your colony to prepare for three quarters and then survive brutal global conditions before the climate returns to normal.

Yayo’s Planet Mod Features

Yayo’s Planet Mod Mod restructures the planet’s climate into a predictable but deadly cycle of yearly disasters, creating long-term planning challenges and high-stakes survival moments.

Yearly disaster cycle

• Every in-game year, the first three quarters are relatively normal and serve as preparation time.
• During the 4th quarter, a major global disaster event strikes the planet.
• At the end of the 4th quarter, temperature and weather return to normal until the next disaster year.
• When a new game starts, you can immediately see which type of disaster will hit in the 4th quarter.

Disaster types

• Ice Age: Extremely cold global temperatures, demanding heavy insulation, heating and stockpiled food.
• Inferno: Extremely hot global temperatures, turning cooling and fire prevention into top priorities.
• Sandstorm: Numerous tornadoes that cannot cross walls and cannot damage anything indoors, rewarding solid base construction.
• Despite seeming impossible at first glance, all disasters are designed to be survivable with good planning.

Difficulty settings and temperature control

• Disaster intensity and temperature impact can be adjusted through the mod options.
• Allows you to tune the challenge level to match your preferred difficulty.
• Tip from the author: standard air conditioners become ineffective in very high temperatures, so use a wooden air conditioner in extreme heat.

Recommended mods

• Dubs Bad Hygiene Mod: Adds more items and systems related to temperature control and environment management.
• Yayo’s Nature Mod: Changes the biome every 60 days, combining biome shifts with seasonal disasters for a more dynamic planet.
