For resources, there are several methods to obtain them currently: harvesting*, searching in the houses in ruins*, looting the bags of the dead survivors in zero danger regions and equipping a survivor to go gather them (you haven't found her yet, Isabelle). I still need to add 2 or 3 special regions, one for harvesting rare resources and one (or two) for resource trading.
* The further you are from the base, the more resources you get from its methods.
If you like Anne's content and want more zombie girls, go check near the bed in the basement, there should be a green question mark that unlocks the quest to find Amelie (Anne's sister). I still need to add Anne's 2 daughters (4 zombie girls).
Sorry if I'm not progressing fast enough in creating the animations for the human NPCs, but I'm busy working on new NPCs that you will have to fight and if you win, you will be able to have fun with her. Sexual content without quest.
Otherwise, all the women in the base can be spied on in the shower and it is possible to have fun with Jeanne. She will make you cum in different ways
