BlazBlue: Cross Tag Battle

BlazBlue: Cross Tag Battle is a game in the BlazBlue series planned for release sometime in 2018 for PlayStation 4, Nintendo Switch, and Steam. It will be published by Arc System Works in Japan and by Arc System Works America in North America. The game combines four franchises: Arc System Works' BlazBlue, Atlus' Persona 4 Arena, French Bread's  Under Night In-Birth, and Rooster Teeth's  RWBY.

It was revealed at the main stage of Evo 2017.

Information
BlazBlue: Cross Tag Battle does not take place in the main BlazBlue storyline, but is said to be a possibility. The main story will focus on the crossover of the four series, and Guilty Gear characters will not be present. Futhermore, there will be no arcade version, and it will be a straight release to consoles. Mechanically, it will be different from BlazBlue.

Development
At the time of the game's announcement, the "expected" or obvious characters had already been decided for the roster. The game was announced relatively early in its development cycle due to the developers wanting to hear the players' requests for characters.

A playable build was first exhibited in October 2017 at four events worldwide: New York Comic Con (NYCC) in New York (Oct 5 -8), South East Asia Major @ GameStart 2017 in Singapore (Oct 14-15), RTX London in London (Oct 14-15), and Arc Revolution Cup 2017 (Arc Revo) at Toushinsai in Tokyo (Oct 21). Arc Revo's playable demo featured an updated build referred to as the "Toushinsai build" in the gameplay manual, which included the third introduction trailer's characters as playable except for Weiss. Following these events, Arc System Works put out a survey on BlazBlue: Cross Tag Battle's official website in both English and Japanese requesting feedback from participants of any of the four events. It was available until Nov 8, 2017 at 8 am PST.

Cross Tag Battle's first gameplay video was released during New York Comic Con, on Oct 6. Character trailers and additional gameplay videos are shown during the monthly Arc System Works Official Livestream, aka ArcNama. ArcNama is streamed on the third Friday of every month at 8 pm JST simultaneously on Twitch and NicoNico, and its first episode was streamed August 2017. Arc System Works also published an article with updated screenshots of gameplay for the newly-announced characters Weiss and Hazama during RTX London. An additional character trailer (Character Introduction Trailer #2) was revealed at RTX London 2017.

A "Special Promotional Trailer" was broadcast during Arc System Work's Fighting Game Awards at the end of the BlazBlue portion of the tournament, prominently featuring and introducing all twenty characters that had revealed up until then, as well as revealing the Japanese release date, Blake, and the final character count of forty characters, twenty of which (including Blake) would be DLC. This was followed up with further details about the release, including the North America release date, prices for physical and downloadable versions, and details about the limited edition. Furthermore, it was announced that Arc System Works would appear at EVO Japan with a new demo featuring twenty playable characters.
