You just need all DDs to get the southern route in 3-2. You can use ANY DD for that, but it is recommended to use the ships that have good stats. I finished it with 6 DDs on Kai and FULLY MODERNIZED Firepower, Torpedo and Armor. Preferable equipped with the night battle Double-Attack setups,

It might take a while to finish the map because the pre-boss node and its compass can be shit sometimes, but with persistence, it can be done.
