4 corner exit map

This is my little hand drawing of the 4 corner map ... I will keep this simple
the lines are the single spots and the shaded parts are the boxes aka areas for grouping totower
On this map u need to build either:
top left & right or bottom left and right.
this map requires 2 people building maze 1 shadow and 1 mount.
the dots I put on the map are possible spots for shadow and mount buff ttowers.
the highlight lines are the maze spots.
the bottom large box should be left alone when building bottom.
The 2 smaller boxes top right or bottom right need maze with buffs.
this map is about building alot of lv 3 maze on both sides with strong buffs and good stun's.
wave 9 has fast moving mob and building properly on twist and turns will slow them down
