The Fall of Nakayama is the final mission of the DLC Hammerlock's Hunt in Borderlands 2.

Summary

In this mission, you must head to the peak of Candlerakk's Cove, fighting Savages and other enemies along the way. Once you make it to the top, you board the H.S.S Terminus and go up against the final boss of the DLC: Jackenstein, a huge Bullymong with two electric generators stuck on its back and a robotic Handsome Jack head in a hole in its chest. Once you defeat him, you go face-to-face with Professor Nakyama, who promptly falls down a flight of stairs and dies, leaving you to a huge room full of loot, and concluding the DLC's main story.
