If you want to get your zombie apocalypse survival on but lack the patience to wait for the DayZ standalone, coming later this year (hopefully soon), I might suggest getting the mod on Steam. If you own Arma 2 and its expansion Arma 2: Operation Arrowhead — or the Arma 2: Combined Operations bundle — than nothing is stopping you from getting the mod. It’s free, so there isn’t much risk involved. If you haven’t purchased Arma 2 yet then you won’t have to wait long. In a recent Reddit AMA, DayZ creator Dean Hall said he expects the standalone to release before April.
