One of the things that makes zombie survival sim DayZ so difficult is that players start the game without a map. Even later on, getting hold of one can be tough. Without a map, you can't see where you are, and if you don't know where you are, you have trouble finding other survivors.
Sure, you can get around this by just downloading a map, but that's hardly as authentic an experience as buying a large, $15, real-world map to have sitting next to you, is it?
These were first printed up last year, but given DayZ's popularity - and its lack of map - ArmA II developers Bohemia Interactive have decided to start selling the things.
Other recommendations for a more authentic experience: drink a can of pepsi every hour, shoot the first person who knocks on your front door and don't go climbing ladders with your pistol drawn. Even in the real world.Chernarus Map Collection + 8 Bonus Postcards Via Bohemia InteractiveKotaku
