Quests
At the moment, there are no quests available within Project Zomboid ever since the removal of the Baldspot & Kate tutorial. Quests will be added as development continues. However, the people, items and circumstances involved with quests may be different each time a new game is started.
Future possibilities include: the player encountering random NPCs that need Items, player may have lost relatives, player may be able to trade information for a stash of goods, and more.
