As previously announced, Bandai Namco elaborated further on its Project LayereD and its associated mobile game LayereD Stories 0. At Tokyo Game Show 2017, pre-registration for the game was officially announced.
To recap, the game has a rather interesting setting where the boundaries between Anime and Game are crossed. What this actually means at this point is unknown, but during Tokyo Game Show 2016 where the game was first announced, Bandai Namco stated that this would be a game made for everyone. Just about every asset in LayereD Stories 0, from its character design, illustration, voiceover work and even the theme song are contributed entirely by teams of volunteers.
