While Let It Die is a free-to-play title, because it was rated CERO Z in Japan, they need to charge 108 yen (approx. $1 USD) to make sure that users who download the game are able to use a credit card. The 108 yen will be given back via in-game items.
A physical version of Let It Die will also be released for 6,900 yen on March 9. It includes an otherwise unobtainable decal and more than 10,000 yen worth of in-game items.
Let It Die launched in North America and Europe on December 3.
