Thanks to Game Watch and the German PlayStation Store, we know that the Yuffie content will be separated into chapters, much like the core Final Fantasy 7 Remake experience itself. Specifically, Yuffie’s episode is comprised of two chapters, where as the main game is 18 chapters as you are probably aware.
The mission sees players controlling Yuffie, a material thief hailing from the far-off continent of Wutai, as she teams up with newcomer Sonon to steal the Ultimate Materia from Shinra HQ. From what has been shown so far, it appears you;ll be playing as Yuffie around the same time as Cloud is spending time with Aerith.
Final Fantasy 7 Remake Intergrade is scheduled for release on PS5 on June 10, 2021. The game will feature a number of visual and performance enhancements over the PS4 version, but Square Enix has said that it won’t take full advantage of PS5 – we’ll have to wait until FF7 Remake Part 2 for that.
