pegasus (DayZ)

Thank you for the responses, I think I'll just buy it on Steam ($29.99) Another question though... I have been watching many videos on youtube of DayZ, some have great graphics and others don't. I know this depends on the players computer rig, but are there graphic patches to boost performance?

I want to start playing this game, it looks like a lot of fun. I'm looking online to buy ArmA 2 : combined ops, and my question is, do I need to buy a brand new copy of the game or can I still play online with a used copy? Thank you
