3 crucial elements are required to maintain the Camp.

1. Water
Although water can be acquired from the Water Well within the Camp, it may not be enough for survival. Insufficient amount must be satisfied by exploring the Riverside, Open Field or Shopping Center.

2. Food
A small quantity of Food can be acquired from the Farm in the Camp at a certain rate everyday.
Insufficient amount must be satisfied by exploring the Farm, Open Field or Shopping Center.

3. Survivors
The number of zombies trying to run over the Camp increases as the days pass.

To nullify the threat, regular increase in the number of Survivors is required.
Additional Survivors can be found either by searching or by rescuing those in danger.

However, as the number of Survivors grows, the amount of Food and Water consumption increases, so be sure to have a good balance between both.
