Before anyone says anything, I'm going to say this: This is not what I want on Day one, and should not be incorporated until development of Stand Alone and the Chernarus map is complete! I actually understand game development having worked in the industry myself
But yeh, at some point, I think it would be very cool to see Atlis (the Arma 3 map) put into DayZ SA. Im not sure how they'd do it, whether as a free or paid DLC, but it would be very cool to have Atlis turned into another infected DayZ world.
Having just watched a heli tour of the island (http://www.youtube.c...h?v=Ck_xHGqZ4Vg) and seeing the detail in the landscape and size of the cities, I think it would be an awesome experience. I do however think that the map would need some work first though for DayZ. With more towns, villages and cities incorporated into it as there is a lot of rolling hills and empty rural areas at the moment. And thats why it shouldn't be done until SA itself is complete as it would take an awful lot of work.
Hopefully others will agree with me on this after they've seen the video because.....well, just look at it, it's some of the most gorgeous believable scenery I've seen in a video game.
