arrowhead or arma two

[Mewtwo 1]

Do i HAVE to download the combined operations set or is there a way i can run dayz with either arma 2 or operation arrowhead?

Arma2 & Arma2 OA or Arma2 Combined operations (combined operations is just Arma2 & Arma2 OA together)

You need to download BOTH. Which means you have to install Arma 2 & Arma 2 OP

You can buy ArmA2: OA and get the ArmA2 free version but then the graphics will not be that good.

This.

You can also get the British & Private Military DLC's for Arma, and some skins in DayZ will look even better.

A slight change in appearance never hurts.

Completely optional but if you want little extra out of DayZ go for it.
