Objective: Meet up with Nele

Failure Conditions: Don't fight any enemies on the two closed Heliports, don't let them be captured either, and SP9 or J retreats. 

This is one of those maps with some random enemy spawn locations, so you'll have to adjust your strategy depending on where the starting enemies are. Thankfully I'm pretty sure it's just the first few enemies that spawn in near you, so you shouldn't need to make any huge adjustments.

As the...probable failure condition states, we need to make sure nothing is in the immediate area we start in. Our first turn will be mostly dealing with that. To start with, we want to take out the enemy that starts closest to us. It can spawn on any one of the red nodes that connect to our starting closed Heliports. Use SP-9 to take him out. Next, we want to position SP-9 to intercept the enemy that starts on one of the Heliports around our closed Heliports. Just leave her on the node that connects to the enemy Heliport. Now, we can move J to get him going in the right direction. 

Move out of the closed Heliport area to the right. We want to take the path that goes up here, so move J up one node. End the turn.

On turn two, move J to the left two nodes, then down one node. We end the turn here, as the target is on the hidden pathway to our left. On turn three, we can move to the left twice, then down one node to end the map.
