Find Nakayama's lost audio diaries
XP and money
Know thy enemies, minion. If you are going to take down Professor Nakayama, you'll do well to learn everything you can about him. I think the tool lost some of his audio diaries. Go find them.
Nice job finding those echoes, minion. Come on back when you are done.
You've learned a little something about Nakayama. Nothing that will actually help you kill him, of course, but still - something.
Follow the waypoints on your minimap and collect all of Professor Nakayama's Data Recorders.
Use a Fan Boat to help you navigate to your destinations, but watch out for Enemy Fanboats. The data recordings are located around Scylla's Grove in The Sun Swamps, The Ardorton Docks, and Grifter's Reach
