Shadow Hearts: Covenant Secrets and Unlockables (PS2)

Shadow Hearts: Covenant is a console role-playing game developed by Nautilus and published by Midway in 2004. It is a direct continuation of Shadow Hearts and the second official game in the Shadow Hearts series. The game features two DVD-ROM discs instead of the usual one, which provides, according to the publisher, over forty hours of gameplay. The game is also known as Shadow Hearts II. This is the name used within the game itself: the name "Shadow Hearts: Covenant" was used only on the American and European packaging and in advertising.

The story follows six months after the events of Shadow Hearts in the midst of World War I. The heroes are drawn into an intriguing plot involving the demons of demonolatry, the chief advisor of the tsar of Russia and a man from main character Yuri's past. The release of Shadow Hearts: Covenant generated much more fanfare than its predecessor. As such, the series gained a much wider following in the United States. (Wikipedia)
