The final mode featured in the game is your traditional online
though its really anything but traditional when you have
robots fighting each other and transforming all over the battlefield.
According to one Redditor the new races are known as Nanites and Frames,
though if you look further into what they're saying it sounds as
though SIVA Nanites from Destiny 1: Rise of Iron have infested Frames,
robots used around The Tower and by Lord Saladin, and that's what we'll be
fighting.
