Following the reveal of NieR: Automata‘s cover art, today Square Enix showcased via press release the pre-order bonus that will be available for the game on the Japanese PlayStation Store.
The bonus is a skin for the pod named “game machine,” which is an obvious callback to the original PlayStation. You can see it below.
Incidentally, some store-specific bonuses also imitate the colors of the old Super Famicom and Sega Master System, you can see those here.
The game will be released in Japan on February 23rd, 2017 for PS4. A western release and a launch on Steam have also been announced, but have no date for now.
