NieR: Automata made its presence known this past weekend at Tokyo Game Show 2016, namely with a 24-minute action-heavy gameplay demo, but Publisher Square Enix also announced that the game will be getting a playable demo sometime this year, though it has not been confirmed if it will make its way to the West (but it would be smart to do).
On top of that, Square Enix also showcased the game's Collector's Edition, known officially as the "Box Edition", which comes with a special box, a figurine of the character 2B, a novel, an art book, a soundtrack, and some sort of bonus download code.
NieR: Automata will release on February 23rd, 2017 on PS4 and Steam.
