2B from the stellar action RPG, Nier Automata, was revealed to be the first DLC character (as well as second guest character) in the game, about a month after Soul Calibur VI's release. There was a trailer, dlc pack specifics, and a gameplay demonstration for her but still no release date given. This was allegedly due to some technical issues that Project Soul was having with the character, that they wanted to fix before her arrival. Judging from how long the gaps between DLC characters released for Tekken 7 were (both major Bandai Namco fighting games), it seemed she may not be releasing for months. Thankfully Bandai Namco just confirmed via tweet, that she would be coming next week on December 18th.
2B is set to come with new music, accessories, weapons, a new stage featured from Nier Automata, and an alternate outfit for both herself and character customization. Not only will her style be able to be used by created characters, but she will also be the first guest character who is fully customizeable.
