DayZ attempts to portray a realistic scenario within the gameplay, with the environment having different effects on the player. A character may receive bone fractures from damage to their legs, go into shock from bullet wounds or zombie bites, receive infections from zombies or diseased players, or faint due to low blood pressure. Thirst and hunger must be kept under control by finding sustenance in either cities or the wilderness, with body temperature playing a key part in the character's survival. The game focuses on surviving and the human elements of a zombie apocalypse by forcing the player to acknowledge basic human needs like thirst, hunger and shelter. These mechanics require the player to focus on immediate goals before they can consider long-term strategies.
