Bug
This achievement is bugged so tutorial is really stupid (but works!)
Here’s how…
Map : Oxfordshire
Boulder : Normal
Difficulty level : Normal
Troops: ONLY BULL OF HEAVEN !!!!
This worked for me
Do not use lightining (cable)
You can use USB – C
End.
Hope that will help you to get 101% of this game
