Family

Family buildings consist of 4 unique buildings that are only accessible once a shut down ending was chosen. They were added in update v1.0 to The Forest.

Gameplay
The family seems to be a consolation prize if you choose the game ending in which you did not save Timmy. This ending means you are not going to kill other people or bring them into this nightmare to save your son.

This may be a result of the main character realizing that he will not be able to rescue his son ( by escaping the island ) - and succumbing to loneliness and/or insanity.
