Depends what you want to play buddy.
If you want to play DayZ, here are the maps to scroll down through and learn and view it. When you spawn in DayZ, you have to keep an eye what the second name is (Chernarus selected):
http://dayzdb.com/map#2.052.080
As far as in Wasteland, you have three teams. Blufor and Opfor, dont friendly fire. Watch the dots And as Imdependant, well make a team / person with you and destroy them all.
I will provide more information soon.
If you have bought the game already, during voting, let it known by this post please.
Cheers!
