: A hidden immunity stat determines your resistance to diseases like Cholera (from dirty water) or Salmonellosis (from raw meat). Maintaining high energy and hydration levels boosts this immunity, potentially allowing you to consume "risky" food or water without getting sick.

: Loot is not static. Events like Helicopter Crashes and Military Convoys spawn randomly across the map, providing high-tier weapons and armor that cannot be found in standard buildings.

: The world lacks a mini-map. Players must use physical cues like white town signs, sun position, and topographical maps found in-game to navigate.

: Every character is assigned a specific blood type (A, B, AB, O, and Rhesus factors + or -). Giving a player the wrong blood type can cause a fatal hemolytic reaction, making blood testing kits and compatibility charts essential for group play.

DayZ Standalone features several deep, informative mechanics that distinguish it as a simulation-heavy survival game. These systems require players to monitor various complex biological and environmental factors to survive.

: Carry weight and clothing type affect the noise you make. Moving slowly behind a zombie with a light load allows for a "silent takedown" with a knife, which is often safer than using loud firearms.
