Some players have sunk thousands of hours into DayZ. It's just that kind of game, harkening back to its humble days as an Arma 3 mod, that draws players in and keeps them enthralled with addictive, challenging gameplay. PvP fans as well as those looking for a cooperative game will find themselves at home with DayZ, and like a lot of zombie titles, it's great to see threats beyond the undead, like the environment, starvation, and of course humans, keep the player on their toes.
