to get the Master Excavator
achievement the most easiest/fastest way then follow this solution!
The following settings is what you want to choose. -
Bots - You will want to Disabled
them and you can only do this if you have a second controller.
Game mode - Capture the Flag
Time - 1:30 - But if you're having problems understanding the controls then put it on 2mins. But 1:30 is more than enough time.
Map - Make sure you pick Runed Palace
Okay now when you start the match go straight for an Bow and arrow
symbol. After collecting one go to another one. After that keep pressing
and move around to destroy all the walls.
The reason why we're using the Bow and Arrow is because once you upgrade it it's arrows explode when touching something so a bunch of wall will go at once.
If you watch the clip below you will understand.
This achievement doesn't take long at all with this method.
