Go And Get My Gears
I planned to create an outer ring of shields surrounding the deeper zone. For a first, this would create a buffer zone to stop any incoming locusts. I didn't want these mad dogs to find their way here to my scrap gathering army.
And a second, I'd protect my forces against any incoming attack from my shield offensive skill.
As I did this, I returned back to the frontline again and started working over the places I left behind.
The shield offensive attack was strong enough to kill all the locusts there. However when I returned, it was expected to see lots more of them there.
This wouldn't end. And the enemy would keep throwing them like they were nothing in return for stopping me from getting more gears.
So this time I left those locusts to my warriors inside the shields and started to move towards zones I didn't cover before.
I copied what I did before, covered the entire land with bubbles of my shields with warriors without any stat points inside to lure the locusts around.
