Clear Steps

Let’s get this out of the way. Yes, you can in fact, destroy the Rubble with a HOC. However, it has 9,999 HP, and BGM deals Damage equivalent to Peirce. That means that even a level 100 BGM with maxed, or near maxed Chips is going to need over 10 shots to destroy the Rubble. That is at least 1500 Ammo and Rations to kill that rock. For a slightly shorter clear is that price really worth it? 

With that aside, this map is a pretty fun little runaround. The Smasher’s should be avoided, but it’s an easy task, given predictable patrols and amply available AP. Another deactivated Bean provides the cheaper want to open the path to the Command Post and a quick victory.

Turn 1


Deploy a Combat Echelon on the Command Post, and the left Heliport. Deploy a Dummy Echelon the right Heliport


Move both Combat Echelons up three nodes. 

Turn 2


Move the right Combat Echelon up-left two does, up one node, right one node, up one node, right one node, and down one node, to the Console. Activate it, and open the Gate.


Deploy a second Dummy Echelon at the bottom. Location doesn't matter on this one. 

Turn 3


Move the left Combat Echelon left one node, down one node, and up-left three nodes, to the Bean. Pick up the Bean. 


Use the Bean to blow up the Rubble. 


With the path free, move the Combat Echelon right ,and up twice to finish the map.
