Required items: bullets, food / water.
Event 1: during your apocalyptic adventure you will have the opportunity to meet the mutants who in exchange for food or water will offer you their protection against the bandits, accept their request and give them something!
Event 2: You will meet doctors, but beware stay away from those who "look like doctors";
they will ask you for hydrogen peroxide to refill their med kits, sacrifice a bottle of water and they will soon be back with med kits or bullets!
Event 3: At the door of the shelter a woman will arrive with a firing weapon, she looks very dangerous but she is just asking you for bullets to hunt spiders. Give her those damned bullets and after a few days she will come back with some food!

In this section here is the list of achievements with a special or hidden interaction based on the choices you have made during the apocalypse.

This is the end
You must let yourself be captured by bandits, for success it would be better for you not to have weapons or objects with which to defend yourself.

Rescue time!
Required items: Gas mask, Radio, Axe, Map, Flashlight, Scout book and the Gun.
As you play you will receive a radio option "We can't be the only ones out here ... maybe we can get in touch with someone"
This will start the military ending. Continue to play normally and carry out the various requests that the military will ask you to make and wait for their arrival, when you will hear the door knocking repeatedly or violently and you will have the option to open the door or not - you agree to open the door and you will be saved by the military.

Bughunter
When they ask you to kill the cockroaches with different weapons or objects you refuse and go to the next day, keep playing until they tell you it is time to kill them (after 2-3 times you refuse to deal with them) at that point it is time to use the insecticide against cockroaches and you will unlock the achievement. If you do not unlock the achievemet you have done something wrong; you may have used the insecticide too soon or if someone in the family gets sick from the cockroach infestation it is too late to use it.

Friend in need
Required items: Medkit, Axe, Map, Flashlight, Soup.
When the game gives you the option to exit but it's too dark to do it use the flashlight, when Pancake comes back at the door give him a can of soup and the next time he shows up asking you to follow him use the map or the axe; at that point the next time he shows up you should have a medical kit for him and if you cure him he will be a new member of the family! Don't skip a single option or you'll never see Pancakes again!

Lumbersexual
You will need an axe to cut Ted's beard when the game gives you the option to do so, but be warned this goal is more complicated than it looks; very often Ted will suffer from stab wounds and you will have to restart the game several times before unlocking this one .

Miracle
Required items: Radio.
Follow the instructions step by step, if you don't unlock theachievemet, restart the game as you can only unlock this achievemet in the first week of survival!
On day 3 tap the radio once and you should hear a static sound, wait for the sound to end then click on the radio again and hear a banjo sound, wait for the sound to end and click on the radio again to hear people talk strangely at that point go on until day 7.
On day 7 click on the radio and listen to the static sound and when the sound ends repeat this step another 2-3 times until you hear the voices at that point you should have achievemet unlocked!

New order
Required items: Timmy, Gas mask.
At the beginning of the game at the earliest opportunity you should send timmy on an exploration with the gas mask until he returns to tell that he met the police at the police station. This achievemet is only unlockable in the first 25 days, if you pass these days and you haven't unlocked the achievemet yet, restart the game, to make it easier to unlock it play on Little Boy difficulty.

A New Hope
Required items: Axe, Scout book, Checkerboard, Map, Medical kit.
When you hear the phone ring send someone to answer so you will activate this ending, passing the days someone will come knocking on your door looking for help (you will have to help the stranger to save his twin) They could also contact you via a note telling you to send someone without weapons since they have already observed you and know that you are good people, in this case you will not have to save any twin but send someone to the meeting.
When you will be contacted by the twins or by the inhabitants of the wasteland continue to comply with their requests until you hear someone knocking on your door insistently or violently at which point you open the door and you should be safe and unlock the achievemet!

Unbreakable
Required items: Axe, Gun, Lock, Insecticide.
Defeat three bandit attacks in one game.

No stone unturned
Required items: Axe, Map, Flashlight, Medkit (optional).
During your survival game you will find a door and you will have to inspect the room with a flashlight, later in the game you will hear some strange noises coming from the floor and finding a hatch you will have to use the axe at which point you can get injured and if you can / want use the medical kit to treat the wounded, a few days later the map will detach from the wall revealing a safe, there could be a treasure inside, what do you do with it? OPEN THAT SAFE! Skipping even one of these options will not allow you to unlock the achievemet.

Disco Roach
Required items: Harmonica.
If you are in possession of a harmonica this random event could happen to you, your characters will want to sound like in fairy tales and be surrounded by mutant and radioactive animals, make them play and enjoy the show, no one will get sick, you will be invaded from the cockroaches that will never leave until you play the harmonica a second time and unlock the achievemet, you will also earn a bottle of water and a soup!

In this section you will find achievements with a special or hidden interaction, but you can rest assured that it will not be a walk in the park as the developers have lowered the percentage of events but don't worry, when you have them don't waste the opportunity!

Enigma
If you have Dolores in the shelter this random event could be activated where she will ask you to crack a code, accept and Dolores will immediately get to work; she after a few days she will solve the riddle and she will have to go alone in the described place when she comes back you will have unlocked the achievement!

Men in Black
This is one of the easier endings. The first thing you need to do is take the cat from the bum, a few days later the cat will play with a thread mistaking it for a ball, examine the thread.
Wait for the agents who will come to give explanations and listen to them, at this point follow the instructions of the agents and when you have completed all the objectives provided by them you will hear a knock on your door with insistence, open up don't worry!

Soup Can into Space
To get this ending you must first take the cat from the bum, when the game will give you the option to visit the address on the cat's collar - refuse, if the cat plays with the wire - refuse to follow the cord, nobody cares to know where bring that damn thread, after a few days the cat could go away from the shelter secretly sometimes and will ask you to find out where it wanders, refuse this time again, finally the mad scientist should arrive who will show you the way to the stars do everything he asks you and when he tells you to send someone for an experiment you know that someone will die so send Timmy or Mary Jane and don't use the medical kits with them so they won't be needed; at this point wait for the scientist to knock on the door insistently and open it, put on the space helmet and go to infinity and beyond!

A gift
Random event where a suitcase will appear, you should try to open it but it will not be easy to have the achievement, often opening the suitcase you will incur illness but do not give up sooner or later you will have this gift, unfortunately it happens 1 time for each game and only if you do not have a suitcase do not waste the opportunity!

Liberation
To unlock this achievement you will need gun and at least 2 family members, when the bandits arrive do not use anything against them so they will kidnap a family member, after a few days the game will tell you that he is fed up with the camp of the bandits and that something must be done, use the weapon that shoots and become a hero!

Take that, Brundlefly!
Have you noticed that fly that sometimes appears in the shelter? CRUSH IT, IT IS TOO ANNOYING!

New species
Requirements: Mary Jane.
There are 2 events that have a VERY low chance of turning Mary Jane into a mutant so don't waste your chance!
Event 1: Spiders will invade your shelter DO NOT USE ANYTHING so the family will attack them with their hands and feet; if MJ gets bitten by one of them she will transform the next day.
Event 2: A green liquid dripping from the tube do not use anything to stop the leak and hope that MJ will transform the next day!
This achievement is very difficult as the chances of a transformation are only 0.5% and sometimes 2%!

Danger zone
Required items: Medical kit, Gas mask, Gun, Radio, Map and Flashlight.
You have to use and break all these objects in a single game to unlock the achievement, I recommend you do it in Tsar Bomb difficulty so you will increase the chances of success.

Konrad style!
Survive for 111 days, I recommend you do it in Little Boy difficulty.


Naysayer
Win by always saying NO to family requests, I recommend the Little Boy difficulty.


Yes Man
Win by always saying YES to family requests, I recommend the Little Boy difficulty.


Cuckoo's nest
Make the whole family go crazy in a single game without anyone dying, being kidnapped or leaving the shelter, I advise you to use the Fat Man difficulty and not to use the harmonica, the cards, the checkerboard, the suitcase and above all when the kids ask you to play or go out to refuse their requests, if the game wants you to talk to a family member just ignore it, no animals are allowed, don't help anyone in the wasteland; the only thing you can do is get supplies from the neighbor / kindergarten / home for the elderly.

Raining Cats and Dogs
First of all you have to get Pancake in the shelter, then you will have to wait for the bum to arrive to offer you the bag where the cat is inside (the chances of this happening are very low when you have the dog), I recommend using the difficulty Little Boy.

Dawkins Residence
Requirements: Dolores, Radio.
A random event could happen by telling you, "We heard what sounded like a female voice ... should we tinker with the radio?" accept, when the game warns you of this: "We heard on the radio a girl who had a horrible ending .... she lives in our country! Should we go to her house?" accept and you will unlock the achievement.

Not Alone
Required items: Harmonica.
Choose to tinker with the radio when the game warns you of a strange radio signal giving you the option to activate a mysterious broadcast, a 2nd event will follow which will allow you to investigate by visiting the woman's house, do not investigate!
A 3rd event will trigger for you to use the harmonica, use it and you'll unlock the achievement!

Tora! Tora! Tora!
Hit 1337 obstacles in the house, I advise you to hit as many objects as possible in the kitchen, in Timmy's room and in the living room, they are the areas with the most objects, it cumulates over time but I have included it in this section for the timing since 60 seconds is not even enough to collect the useful items, you should focus only on this goal.

In this section i included the newest achievements to unlock.





Cat Lady & Feline Domination
You will unlock these two trophies together
Just focus on this ending to unlock it!
Must say no to agent events (investigate wire)
Must deny scientist requests (soup/water)
You will need Sharikov (the cat) and lots and lots and lots of soup! is essential for this ending.
Wait for these options:
"Sharikov was playing and we saw a thread, should we follow him?" "YES"
"We need to talk to the FBI agents" No "
"We found an address on the collar, should we go?" "NO!"
"Sharikov came out of a small hole should we follow him?" "NO"
"We found a fridge outside should we take it to the shelter?" "YES"

Now you just have to keep playing and every time a new cat appears click on it to read the name (Don't forget to read all names, including Sharikov's) and you will finally unlock these two trophies!
