the story

first part:

The end of the world has happened and you are a twenty year old man looking after your little sister. The main point of the first part is to show you how to start your town, go out looking for surprise and build it up e.g. walls, new houses, clean, water, food and weapons when the time comes. Just as you get a good thing going in the town new people turn up looking to settle with you. you  hear of a rare item, which is a type of terraforma, so you set out with two others that you choose to look for this. but your little sister follows you. you been unaware of this get to the base and find it but one problem. a sand storm starts up and just as you find out your little sister is following you, you get split up and fall down some rocks and black out.

the middle :

you awake in your bed back in the town after your two friends carry you back to safety. but as you start to get your memory back it hits you that your little sister is out there still lost in the waste. so you have to go out and track her down. starting at where you last saw her, and then going through town and places doing bits and bobs to get some quest to her where abouts, in this you will come across new people and companies that can aid you in your quest. but  at the same time rebuild the town after the storm hit cursing damage. after chasing clue after clue going some leading to dead ends you finally found her in a small town mile from the home, the people there have been looking after.in this part you must rebuild up your skills and this will determine the ending of the story and also getting high skills on one or more areas can have a add story to it to.

PlOT TWIST 2! they have help her track down the terraforma but someone has got to it first. on your way to for the second time you hear planes and helicopters overhead, it turns out the army got to it first.

End

this is where you must choose what you can do do use the skills you should have learned over your travels;

sneak in and take it without them knowing or killing anyone,

take it by force killing and shooting everything that moves. e.g. the usa way

trade for it money/weapons rare thing they won't.

share, join them and them help you with the town and you help them with somewhere to put a base.

open ended ending. what ever you choose could carry over to the next game. the end is just you and your sister walking off into the waste holding hands (fall out style)
