This guide gives tips specific to this world and it's quests.
You are a group of survivors from a camp called Newhaven that got over-run one night and everyone ran off to escape. The Campaign starts with you and 2 other survivors meeting up on the edge of a forest near the coast.
I would suggest greeting the two survivors initially as this will to get their names, which will allow you to add them to the party by clicking on their names.
Its fine to use the map to explore and say got to location XYZ. Sidney will be giving you maps for quests, so this is all player available information.
You can start by searching the barricade location, and the Survivors Camp location, before going to see Sidney in the Supply Tent. Sidney will give you most of the possible quests when you are at the Supply Tent location. Pixi also has some quests which are given at the Survivors camp location.
As a survival game, you need to search location, collect supplies, and deposit them in camp. TO assist with this, Franz will (should) only create items such as weapons and armour. General supplies are stored as a Memory. When you are at the supply tent, if you 'Drop Supplies' or 'Give Sidney supplies', Franz will transfer the items to the camp and delete the memory (awarding XP). This should help prevent you becoming overloaded. Franz is not 100% at this, so do go into the inventory of your main character and drop anything it has given you in error.
