Still unsure about customization atm since judging from the Reina one, unless most of the content is locked and not visible in the menu until you unlock it in super ghost battle or something, stuff is limited since the generic stuff isn't all that, but it does look like hair will be universal since starting off Reina could equip Lee, and even Leo's hair from the start and Jane's hair is selectable too which makes me think there's going to he a scene with her and Jack 8 in it.
Idc about hair much since Lili already has the best hair in the game so I'll likely just mod and recolor it, but the clothes are disappointing atm. I did see that Jin could wear Hwoarang's clothes so I'm hoping that means everyone can wear each other's stuff and it won't just be relegated to rivals like Asuka and Lili since I really want to have Lili wear Nina and Reina's gear. The music is Also hands down the best in the series so far imo, it's like they took what DOA6 did with their DOA stage tracks and put that more dark vibe into the stage and music production
