Is Za a mod day?ĭayZ is a multiplayer open world survival third-person shooter modification designed by Dean Hall for the 2009 tactical shooter video game ARMA 2 and its 2010 expansion pack, ARMA 2: Operation Arrowhead. The company reiterated this in a tweet via the game’s official account, which clarified ” DayZ development isn’t closed.” DayZ will apparently continue to receive updates throughout the year “with longer games between them,” as laid out in a roadmap published to the game’s website back in January.
