If anyone else is a lazy bastard like me that wants easy mode with cheats, you can go to
You must be registered to see the links
, upload your save file from game folder /save and edit the items so you can have as much stuff as you want. You just have to figure out which item# is what you want to increase and you also need at least 1 of the said item, so that it will appear in the list for you to click and edit.
Here's what I found out so far
item#1 - scrap metal
item#2 - scrap wood
item#3 - food (vegetable)
item#4 - water
item#5 - medicinal herb
item#7 - ammunition (pistol)
item#9 - z-cola
item#11 - wine
item#21 - electric fuse
item#30 - ammunition (crossbow)
After you edit whatever you want, download the file and replace it with the one in your game folder /save, start the game and load it.
