[Mobhack]

The game is designed to play left-right only. Artillery arrives from the sides map edge, troops will retreat to thier map edge, and that map edge shall be the right map edge or the left map edge, nothing else.

Naturally a scenario can be designed to be played a bit diagonally, but up-down tends not to work.

Note that I said right, not East, left, not West. The scenario designer decides where North is and can put some text on the map detailing that. The top of the map is the top of the map - not North, necessarily.
