Creating these since it has been requested by multiple people. These videos will have to be broken in 2 parts since it is not possible to complete all missions in 1 clear. These are very late, but I still hope they prove useful to those who have not yet cleared them.
The strategy for this quest is to generally camp on the bottom right of the map and have the enemies make their way to you as they spawn. This will ensure that the incoming damage is manageable.
This is a dark clear that focuses on the mission to clear with 4 units. This video does not cover the chaining missions. Please see the earth clear for the chaining missions. Although it would've possible to cover the chaining missions as well if I had used Ranell instead of Tytas, I decided not to do so because my Ranell is 140 as well and I did not want to use too many 140 units for the clear.
