The Hong Kong edition was released in Taiwan with an age rating sticker on the front and a sticker from the distributor on the back. The cover insert is dual-sided with the English title on one side and the Japanese title on the other. It contained a manual and a sheet with a DLC code.
There is also a barcode sticker on the front of the Japanese side, where multiple number variants have been observed. However, all copies sold in Taiwan start with 6, while copies sold in Hong Kong start with 3.
1. Front (Japanese title)
