This map is used from the manual in the game's files. Cheers to the devs for making the map!

Ahhh. The yellow dstrict. Home sweet home. This is where you would be able to find your food, Gender Swappers, and go to sleep. If you get lost at places, don't worry! Just follow the yellow arrows, they lead directly to your house! No seriously. They do. You can trade some of your cheaper items (like scrap metal) in the yellow district right outside your apartment. (LocalCaitortot)

I am not really sure what to call this one by, as it has a similiar colour to the yellow district. This is a place to trade wizardry stuff to old men that have butterfly wings on their back. They also sell potion ingredients.

This is the Green District. This place allows you to trade salvage, junk, common to rare items and the lot. You can also trade salvaged tech, if you have any. I don't really find any use in this area, but hey, that's just me.

The Red District, but as I know it, the adventurer district. This is where you can buy weapons and such. There isn't really much to do there, but it has a pretty nice view! There isn't food, and not much to do there, so I would recommend not to go there.

This is the place if you want to go to the bank. Each week I think you can get free money, but not much. It is the smallest sector by far.

Thanks for reading! If you have any tips and such, additions to the districts and facts, or if I just got something wrong, please comment below!
Cheers!
