What is the obsession of this game? Looks like a carbon copy of Dayz/Arma.
I've heard it described as "entry level Arma," in which the mechanics are simplified, faster, and more fluid while taking the better aspects of it and making a tense tactical shooter out of it. I don't know where you got DayZ from, but the main appeal is that it's making a type of FPS gameplay more accessible for a lot of people for the first time and it's proven to be pretty popular.
