Who are the Survivors?
Survivors are the ones who have made it here in search of safety from the bitter cold. Help them out by erecting various buildings to provide food, natural resources, and shelter.

How do I get more Survivors?
You can get more Survivors by adding more beds in the Dorms. A new Survivor will arrive shortly after you add a bed.

Why do my Survivors get hungry, sick, or even die?
It is possible for Survivors to get hungry, sick, or even die. When this occurs, tap the "i" behind the Survivor icon at the top of the home screen to check if the Survivors' three basic needs are met:

- Warmth Needs: Survivors are more likely to get sick when the temperature is low
- Food Needs: When Survivors are hungry, their work efficiency is reduced by 10%
- Rest Needs: When Survivors are exhausted, their work efficiency is reduced by 10%

Why are my Survivors not working?
- They are starting a strike (Strike unlocks once you reach Plain City): Survivors are more likely to start a strike when their Warmth, Food, and Rest Needs are not met
- They are sick: Survivors are more likely to get sick when their Warmth, Food, and Rest Needs are not met (when Survivors are sick, they will go to the Hospital or Dorm to rest)
- There are not enough raw materials: Survivors at specific positions will stop working when you run out of materials
- There are not enough work positions: Level up your heroes to open up more work positions

Can Survivors work at night?
You may ask Survivors to forego sleep in the face of dwindling resources, but keep in mind that this will result in a steep decline in their Rest Needs.
