In the newest Black Ops 3 Cybercore: Control video, it mentions that the Augumentation Breakdown Core is used to “turn an exo-suit against its user”.
This is the first time a reference to an exo-suit has been made in Call of Duty: Black Ops 3. Treyarch has been trying throughout the year to separate their new DNI (the new way your mind is attached to the technology) from Sledgehammer Games’ Exo Suit mechanics, but it seems that there is some sort of an exo-suit in the campaign mode for Black Ops 3.
As a side-note, Cybercores are only available in the campaign mode, so if there are any exo-suits, this will be limited to the campaign mode. As already revealed, Treyarch’s multiplayer has their new, separate chain-based movement system, which fans got to try out in the beta in August. The new movement system in Black Ops 3 is very different and more limited than Advanced Warfare’s movement system.
