Clear Steps

This map is a wonderful, wonderful creation. The Consoles on the map are a puzzle that is far more complicated than it probably needed to be. The rest of the map is fairly straight-forward, with the Isomers suiciding on M4 making the Elimination objective much easier. The difference between the two objectives is fairly small as well. 

Turn 1-2


On Turns 1/2, deploy and move three Dummy Echelons onto the Consoles to the far right of the map as shown. 

For the sake of my sanity, the Dummy Echelons will be referred to as 1 2 3 and the consoles in turn.

Turn 3


Deploy a Combat Echelon at the top left from the now-open heliport.

Use Dummy #2 to open the Gate, then move the Combat Echelon to the right three nodes. 


Use Dummy #3 to open the Gate, then move the Combat Echelon to the right two nodes, down two nodes, and then to the left one node. 

Turn 4


Move to the left, and rescue M4. Use Dummy #2 to open the Gate, and move your Combat Echelon up two nodes, then to the right three nodes. Wait for a few turns to complete the rescue. 

Move your Combat Echelon to the left three nodes. Whether you swap with M4 or rescue her doesn't matter? 

Activate the Console with your Combat Echelon. This is Console Number 4. 


Reset the consoles then activate the Console with Dummy Echelon 2, then Dummy Echelon 1. Activate the Console with your Combat Echelon (Console Number 4) then finally, activate the Console with Dummy Echelon 3. Assuming all has gone well, you may now go to battle once again. 

If you mess up at any point, just use "reset" option at any console and start over.  

Move the Combat Echelon to the right two nodes, down two nodes, and to the right one node to bring the mission to a close. 


RNG may cause you to have to take a slight detour if the wrong Isomer slams into M4. This is fine and the mission will still be completed in the same number of turns.
