This is a full playthrough of the first 64 rounds of Dead Ops Arcade II: Cyber’s Avengening, found in Call of Duty: Black Ops III (2015) under the “Bonus” menu. I completed this particular run "flawlessly," or without taking a single death. In order to achieve that, I used my equipment very liberally, which is something I would typically advise against for less experienced players. Nonetheless, I believe there are several useful strategies that can be gleaned from this gameplay for both beginners and intermediate level players.

Note: Due to an issue with my capture device, there are a few instances in this video where the gameplay skips ahead a couple of seconds, though the issue is quite infrequent.

► What happens after round 64?
After defeating the Cyber Silverback on round 64, the game loops over, as you are sent back to the Island arena and have the option to continue playing. While there are no new arenas, the difficulty is ramped up, as the zombies become both stronger and faster as the game progresses, along with the rounds taking longer time to complete.
