Project X Zone 2 is due for release in Japan a week today, and will be released in both a regular edition and a second edition which includes extra features.
With the second edition comes a download code for Adventure of Valkyrie: Legend of the Key of Time with Xiamou – which is a special edition of the game with Xiamou as a playable character. The second edition will also come with a special 3DS theme and a Namco X Capcom 10th Anniversary Resource package.
To give a teaser of the Adventure of Valkyrie: Legend of the Key of Time with Xiamou download, Bandai-Namco has uploaded a gameplay video. You can check it out below:
Project X Zone 2 is also due for release in North America and Europe in February 2016, but it is unclear yet whether or not the download code will come as a pre-order bonus in the West.
