Isomer E1-C3: Beyond the Border III

Possible Drops:


 Mission and Clear Conditions:

Mission: Hold Supply Line for 3 Turns

Clear Guide:

Team Recommendations: 

  •  3 Combat Echelons Level 30 3x at least. 
    • AR/SMG Recommended, or Hybrid Backlines if unable to deal with Armor with ARs alone. M14 is sufficient for this task for newer players. 
  • 1 Dummy Echelons

Clear Steps

A Supply Line control Mission, this map does not offer too much by way of challenge. There are a few Typhons scattered about, but these are a far cry from those familiar to players from Singularity and portions of Continuum Turbulence, as their attacks are perfectly avoidable due to their positioning. The Deathstack Hydra’s on the map even manage to be non-threatening thanks to Patrol AI.

Turn 1


Deploy three Combat Echelons, on the Command Post, and the two flanking Heliports. Deploy a Dummy Echelon on the Bottom Heliport. 


Move the Combat Echelon on the Command Post up one node, up-left one node and up one node. 


Move the Dummy Echelon up two nodes, and left one node. 


Move both remaining Combat Echelons up one node and end your Turn. 

Turn 2


Move the bottom two Combat Echelons down one node each.


Move the upper Combat Echelon up one node onto the Supply Point.


Move the Dummy Echelon up two nodes, swapping with the Combat one.

End your Turn

Turn 3


Move the Central-left Combat Echelon down one node to the Heliport. End your Turn. 

Turn 4


Move the left-bottom Combat Echelon to the right, and down one node each. 


Move the left-bottom Combat Echelon to the right, and down one node each.

The Hydra Deathstacks don’t appear the smartest. While they should, by all rights, capture your Command Post, they appear to be more interested in chasing the Combat Echelons, so the map will clear just fine. Patrol AI is very good, I promise.

Imagine being blind, lmao.
