Tekken Tag Tournament 2 is the next currently planned iteration of the Tekken series of fighting games. The game is the second game in the series to have a focus on tag battles rather than one-on-one bouts. It was announced on September 18, 2010 at the Tougeki event. So far Asuka Kazama, Jin Kazama, Kazuya Mishima, and Leo have been revealed as playable characters along with Heihachi Mishima and Lili appearing in the trailer in non-gameplay situations. The gameplay engine and style are closely based on Tekken 6, and expands on the tag mechanics featured in the first Tekken Tag, allowing for extended tag combos and combined moves. It will be released in Japanese arcades in Summer 2011, whilst release dates for other regions, as well as console versions, have yet to be announced.
