DayZ has a ridiculously large map. The more I think about it, the more I appreciate server loads and computing. There is a lot going on in this game compared to most others.
Don’t believe me? I almost had a hard time believing that the DayZ map was so much larger than some other games maps such as Battlefield 4 and Call of Duty. The following pictures put it all in perspective.

Its just awesome, play DayZ now, if you have no problems with alpha version bugs.
Lots of fun guaranteed.
I am addicted :X
