I recently started playing WCPSO again, but I've hit a brick wall with the "Friends in Need" mission (after you come out of a jump you have to defend the Shy Meadows, Kyoto Rose, and the Cheryis Song). I can't remember how I beat it last time, but I've been trying to take out the Stingrays and Devil Rays in that order and worry about the Mantas later but the Rose and Song keep biting it during the second wave... Any tactical suggestions?
