Insanity is a condition any of the family members can get if the Sanity stat for family members is lowered far enough.
Many different events have effects on the characters' sanity. Generally, more negative acts for events have sanity-lowering effects, but there are several events and acts that can drop the Sanity stat swiftly, ushering in a character gaining an Insane status. Those include: family members dying or failing to return from expeditions, being the only character remaining in the shelter, or attacking one's neighbors. Likewise, several events will boost one's sanity, but the major ones are: getting Pancake in the shelter (100% sanity); the friendly scavengers looking for food, water, or medical supplies (100% sanity); or not attacking one's neighbors (heavy Sanity increase).
Much like Injury or Illness, once a family member becomes Insane, they are on a countdown to being removed from the game. However, the only cure is to raise the character's Sanity. Once Insane, the character can stay in the game for before 20-35 days before they run away. About halfway through this countdown, the Insane character will destroy an item. Every item can be destroyed by an insane family member except the Ammunition and Bug Spray. Each character has a list of items that they will destroy, depending upon what items are present in the shelter; if the first item is not present, the character will destroy the next in the list:
- Ted: Map, Gas mask
- Dolores: Cards, Radio
- Timmy: Boy Scout Handbook, Medkit
- Mary Jane: Axe, Flashlight
Finally, if the character's Sanity is not raised above Insane, that character will be removed from the game by running away. Dolores will try to "find her father", Ted will live a new life with his sock puppet, Mary Jane will leave for what she thinks is her weekly tuba lesson, and Timmy will become a wasteland superhero and run away.
When insane, Timmy will wear a soup can for a hat and hold a teddy bear head (he will also try to puncture one of the teddy bear head's eye, but he will try to puncture the other one when injured, in which the teddy head will have a bandage, and will not puncture any eye if tired). Mary Jane will pose like a chicken and sometimes stand on her seat as well. Ted will look straight at the player creepily and gain a sock puppet (It will have a stitch if Ted is also fatigued and bandages if Ted is injured too). Dolores will just idly pose in a zombie-like position. She is also the most resistant to insanity.
Birthdays Requirements: Bug spray, the Boy Scout Handbook, the Checkers Board, The Medkit, or the Playing Cards.
Summary: It's Timmy/ Mary Jane's birthday. The player should give them one of the gifts mentioned above. Doing so will increase their sanity.
People are at your door asking for items. Required: Food, Water, or a Medkit. If the player doesn't give anything, in addition to the individual event's consequences, all the characters will lose sanity. If the player gives something, to the rewards, all the characters will gain sanity. They may get angry and raid the fallout shelter for everything besides the characters and broken items.
Great Uncle Terry Requirements: Boy Scout Handbook
Summary: The family members wish they had a photo of their great uncle named Terry. If the player uses the Boy Scout Handbook, they find a photo of him, and it helps keep up their sanity. If the player doesn't use the Boy Scout Handbook, It lowers their sanity.
Auntie Ada Requirements: Boy Scout Handbook
Summary: See Great Uncle Terry above.
Timmy, the wild one (unofficial title) Requirements: None
Summary: The family members are worried, that keeping Timmy too long in the shelter might be bad for his sanity. The player can choose to allow him to go outside for a "little" walk or keep him in in the fallout shelter. (Yes / No) Keeping him in the shelter will lower his sanity heavily. Letting him go out May have a chance of Timmy getting sick when he returns, and he also has a chance of getting items.
Bored events Requirements: Rifle, Radio, Checkers, Deck of Cards
Summary: The family is bored and fear to snap because of it, they want to do something against it, If they choose to play Checkers, Mary Jane might snap and become insane or her sanity drops heavily. (needs confirmation)
The neighbors downstairs
Requirements: Flashlight, Axe
Summary: The family hears noises from below the floor, so they decide to go into the manhole near the corner, in which the player can choose to bring the flashlight, axe, or nothing.
"What the hell! We barely made it out alive! It was a giant, mutated crocodile! Or an alligator! Or something else with a giant mouth and plenty of teeth! Anyone hurt?"
Flashlight: See axe, inflicts injuries to one member (needs confirmation).
We found treasure down there! Pills, bottles and other medical supplies were stacked on a few shelves down in a narrow room. Just enough to stock our first aid kit. Good for us. We didn't find the source of the noise (+1 MedKit).
Nothing: "Going into a tight, dark tunnel is not a good idea, especially with those weird noises coming from it. They are giving us the creeps, even up here..." - inflicts insanity to every member. (needs confirmation)
Summary: If Pancake disappears, all the character's sanity decreases. If the player haves Pancake, it can turn all the characters sane again.
Summary: The kids want to play tag. If the player don't let them, their sanity decreases. If the player lets them, their sanity increases but they will destroy some items/provisions.
- There is an achievement that the player gets by making all characters insane. Its name is "Cuckoo's nest" and its icon is the sock puppet that Ted has when insane.Everyone also gains Viking helmets
