This page is for the ARMA II mod. For the stand-alone title, see DayZ.

Key points

DayZ is a modification for Arma 2 and requires its expansion Arma 2: Operation Arrowhead.
DayZ Commander is highly recommended as the best one-stop program to install, update and browse DayZ servers - no other programs are required.
DayZ is in early open alpha stage, and is very unfriendly to install and run for new users, while many bugs, gameplay problems and rampant cheating persist.[1]
