Shelter Upgrades

Your shelter comes equipped with certain facilities that are necessary to your groups survival. These built-in facilities are not removable, but they are upgradeable in order to improve the shelter.

You can click through the links to browse each facilities article, complete with a breakdown of each facility's upgrades, and their tier bonuses and requirements.

The facilities are:

Oxygen Filter -- Provides your survivors with oxygen. The filter can only process so much oxygen at a time, restricting the maximum number of survivors you can have in the shelter at a time.
Water Collector -- Provides the ability to harvest clean rainwater for drinking and crafting purposes.
Water Purifier -- Purifies dirty water from Black Rain or from water recycled within the shelter.
Weather Vane -- Provides weather forecasting so that you can plan based on incoming weather.
