This may be the most obvious thing ever. But I see all of these people on Youtube and TwitchTV playing DayZ and I see them playing the map "Wasteland" I am unsure if this is the original map, and just has a nickname, or if it's a map that is downloadable but isn't yet on DayZ Commander. I would really like to figure out if this is an entirely new map, and help would be appreciated. ~Trip
