Yoko Taro continues on his quest to make sure 2B is in every videogame franchise imaginable and announced at the Sony State of Play, Stellar Blade and NieR: Automata will be collaborating in the future. It's not clear just yet what the collaboration will feature but my guess would be a 2B outfit for the main character in Stellar Blade.
Also included in the update is a brand new photo mode and the soundtrack to Stellar Blade with over 130 tracks will be on various streaming platforms.
The Stellar Blade x NieR: Automata collaboration will release later this year.
