Mission and Clear Conditions:
Find the mind map of the hidden M16
- 4 Dummies
Deploy three Dummy Echelons.
Move the Bottom Dummy Echelon left one node, then the middle Dummy Echelon down one node and then move your top Dummy Echelon left two nodes.
Deploy another Dummy Echelon on the Heavy Heliport and move it to the left one node.
There is a small chance that the Game breaks and the M16 shown below doesn't get defeated by the other one, from turn 1 to turn 2. If that happens you sadly have to restart the Mission.
But you told me there is nothing that can break your Chapter 13 Guides...
I happens Chief, it happens.
