Hey all, I'm new to the community. I saw some dayz footage on youtube randomly and it looks pretty fun so I thought I'd buy it. Some friends and I are thinking about buying this and I guess I just realized you need to buy Arma 2 to play it. Can I just buy normal Arma2 (which is like $15) and play DayZ? Or do I need to buy one of the expansions? Also, are bandits NPC's? Or once you start killing other people do you become classified as a bandit. Thanks ahead of time
