Shadow Hearts (シャドウハーツ Shadōhātsu?) is a series of role-playing video games for the PlayStation 2. The Shadow Hearts series was developed by Sacnoth (renamed Nautilus for the later games in the series) and released by Aruze in Japan and Midway in North America and Europe. However, Shadow Hearts: From the New World was published by XSEED Games in North America and Ghostlight in Europe. Not to be confused with the Kingdom Hearts games which, while featuring shadows, are not related to this series.
