The person to take:
First of all, about the person to take, I think it doesn't matter, some people say, to take the daughter, because the daughter can be mutated, but I would like to say that even if the daughter in the shooting of spiders mutated, but also only increased to allow you to take a few more times! The time of supplies, difficult mode unexpectedly a lot, more supplies does not mean you can pass
Opening must:
The following is the opening must, food and water, at least the same 2 bottles, preferably 3 bottles.
Then the most important, the radio (a must have item to trigger the army mission, don't try to pass without it).
How to get through:
Next are the 5 items you need when the army rescue opens, which are a flashlight, playing cards, map, axe and gun.
If you don't have a gun with you at the start, it won't trigger the army to ask you to throw it, but if you don't have an axe, it will still trigger the army to ask you to cut down a tree, and there's also an army event that asks you to go to the town to gather.
But the bottom line is that as long as you have these items, up front, and trigger these two quests and complete them, then you're ready to pass the level.
After completing these two episodes, you'll want to collect as much food and water as you can, and then just stay at home and never go out, because as long as there's someone out picking up stuff, it's absolutely impossible to trigger an army rescue, remember, so get enough stuff ready for you to eat, and then start getting ready for the rescue at home.
After the two episodes of the army rescue, the people in the house did not go out to pick up things, and then triggered the event of someone knocking on the door, it is definitely the rescue of the army, which is confirmed by my personal game.
The fastest I've ever gotten through it was 36 days on hard mode, and it's usually 40-60 days in that time.
Necessary props:
The book
The artifact, repair all items, need not I say more, can prevent the first cockroach infection.
Insecticide
Can make medical kits, and the pre-bath episode will definitely be used, this is the most dangerous episode in the whole game, without a bath, all of the people in the house will all get sick.
There's also one that says you can't sleep and your biological clock is messed up, use the medkit, be sure to use it, don't be greedy or it will lead to an all exhaustion debuff or even insanity.
Radio
The radio triggers picking up the traveler's items, but make sure not to touch him when prompted to adjust the radio.
Axe
Don't use the axe if you can, it's easy to get hurt.
Guns
Also, after 40 days, if you didn't wait for the army episode, then you must have a gun, after 40 days all sorts of people, robbers, firemen, square dancers, will come to rob you, so make sure to have a gun
Throughout the game:
All in all, the plot triggers, and bring enough food and medical supplies, and the game is really not that hard.
Appear to remind you to eat or drink water, all every other day to give supplies, so you can save a lot of resources, don't more than 3 days, more than 3 days of small children will definitely run.
Wish you all pass soon, this game I have passed, a file from the beginning of the items can be seen to pass, if in 40 days or so there is no radio, or the second task can not be done, it can be combined with the state of the family and supplies, to determine whether the file can pass, and, remember one thing, the purpose of this game is, do not make death.
