Quests can range from killing a certain amount of zombies to looting a house in a specific location. Or you can retrieve them from the Trader NPC. You can find quests in note form from dead zombies, in bags, or by looting. Quests are a reasonably recent addition to the game (in the last few years) and can provide you with valuable rewards. It’s recommended placing a storage chest down to store your items and come back for them when you need them. If you do loot everything, you’ll quickly become encumbered.
