 Mission and Clear Conditions:

Mission: Kill All Enemies


Hidden Achievement: Capture all Nodes (Silver Medal)

Clear Guide:

Team Recommendations: 

  •  3 Combat Echelon Level 90 5x Linked
    • RF/HG Echelons are generally recommended to be able to handle the various Uhlans and Doppelsoldners, but ARs can suffice with enough buffs. 
  • 1 HOC BGM-71, level 60 assumed
  • ​​​​​​​1 Dummy Echelon

Overview & Step-by-Step Guide

EX Difficulty starts out pulling no punches, throwing shielded enemies backed by Artillery Installments at the Commander without any hesitation. HOC usage is important here, mostly to destroy the enemy Artillery, although HOC support will make some of the shielded enemies easier. Aside from that, infinitely-spawning reinforcements are the only major threat present to a prepared Commander. While you can get the Hidden Achievement now, there is no reason not to do so on Normal, where fewer and weaker enemies simplify the process. 

Turn 1


Deploy 2 Combat Echelons and a HOC on the Heavy Heliport. BGM-71 is recommended, and her deployment will be assumed for the purposes of this guide.


Move the Combat Echelon on the regular Heliport down three nodes, swapping with BGM on the way.


Deploy a third Combat Echelon on the regular Heliport. Swap them with this HOC. 


Swap the HOC onto the Command Post and blow up the Artillery under the Doppelsoldner.


Swap a Combat Echelon with the HOC. Move the Combat Echelon now on the Command Post to the left one node, down one node, and to the right one node. 

Turn 2


Deploy a Dummy Echelon on the Command Post. 


Move the central Combat Echelon to the left one node, up one node, and swap them onto the Command Post to resupply. 


Swap back to the left with the Dummy Echelon, then move up two nodes.


Move the third Combat Echelon to the right one node.


Move the HOC up one node. End your turn.

Turn 3

This turn will depend on what movement RNG luck you have had. The route shown will account for the worst-case scenario.


Resupply and move the leftmost Combat Echelon to the right two nodes and diagonally upwards one node to clear out any enemies on the way. 


Move the HOC up one node, swap with the Combat Echelon, and bombard the Artillery Installment. 


Swap with the HOC and move the Combat Echelon right three nodes, then move to kill the remaining enemy to finish the map.
