Tetsuya Takahashi, the director of Xenoblade Chronicles X took to twitter again today, this time to discuss the games plot. The folk at Siliconera have translated the tweets allowing us the gleam some new information about the game.
Firstly it was revealed the main script writer of Xenoblade Chornicles, Yuchiro Takeda, is returning for the sequel.
Takahashi then went on to say:
“After the ‘basic’ fantasy story for [Xenoblade], we’re having him write a deep sci-fi story this time around”
Takahashi went on to reiterate that Hiroyuki Sawano (who worked on Attack on Titan) is in charge off the sound direction & Kunihiko Tanaka (who has worked on a number of Xeno games) is in charge of character designs and Takahashi chose Tanaka in order to "bring out the Xeno-ness in the art".
