If you arrived here from the Normal Mode Guides, you are in fact in the right place. This map requires NO fighting, and thus there is no reason not to clear it on EX for the extra rewards, Crates, and Intel Points!
Please... PLEASE!! DO WHAT HE SAID!
Mission and Clear Conditions:
Mission: Rescue 1 Hostage
- 1 Dummy Echelon
Overview & Step-by-Step Guide:
Isomer’s first map gimmick is a doozy. You can clear the entire map without a single fight, making this a very attractive option for farming both Intel Points and Crates. Given the extremely easy nature of the solution, there isn't much more to say - just make sure the allied Echelon AI is set correctly, or you can brick the clear! This map will reward 10 Crates per clear, so only 6 runs will be needed for your daily Crates.
Move left two nodes, up one node, and swap with the hostage above your Echelon. Move right one more node, swap two nodes to the right with the allied Echelon and the hostage, then swap with the hostage above you. Move left one node, and up one node onto the Heavy Heliport. Manually complete the retrieval to rescue the hostage you picked up on Turn 2, and the map is finished!
