Kingdom Hearts IV Chooses Depth Over Quantity: Fewer Worlds, More Detail

KH4 will have fewer, more detailed worlds than previous entries, beginning with Coco as the showcased world; new mechanics include guitar-style combat and expanded traversal. The story expands with Quadratum and Union χ lore, the script is roughly double KH3’s size, and English VO is about 60-70% complete while Japanese VO has finished as development progresses toward release.
