DayZ does not feature a traditional linear 'main story' or 'campaign' with quests and boss fights in the conventional sense. Instead, the 'walkthrough' is a guide to progressing through the game's inherent survival loop, from fresh spawn to established survivor, and eventually, to base building or PvP mastery. This section outlines a general progression path and key objectives you'll naturally pursue.
Your 'mission' in DayZ is self-defined: survive, thrive, and perhaps interact with other players. This guide will break down the typical stages of a survivor's journey.
