Here it is ..Beastcraft's New Map Layout. The Hero can move Left to Right only. Before this change .. Beastcraft was 3-D (Able to move up, down, left, and right) .. But now it is 2-D, which suits the Game better.
The Idea of the BG (Background) came when other Areas were implemented into Beastcraft .. The Area you see above is the Starting Area known as the "Greenland".
(Example: When you reach a Desert, the BG (and Environment) will change to a Desert. This is New along with the next Update.)
