ArmA 2 is a great game without the zombies but even know you need combined operations for the DayZ mod, the DayZ standalone will be coming out sometime around december. Basically what that is, is you buy DayZ just like you buy WarZ it has its own launcher, which means you don't need to buy ArmA 2 CO, to play it. For now i'd just wait till DayZ standalone, but you could always get WarZ and get DayZ later on.
