Yes this game has events from volumes 22-27 of the manga and a side story by Kentaro Muira. The DC Berserk game was all an original side story by Muira, it was nice but I think fans wanted events from the manga in that game. If anyone is interested in reading the manga and doesn't want to wait so long for Dark Horse to bring em out, then I suggest getting Japanese volumes like I did. If you can read Japanese, then good but I used translations from skullknight.net
The best place to get the Japanese volumes is at a Japanese book store or

Shipping can get expensive but the manga is always $5-7. I own volumes 1-20, but ive read up to 28 so I was well ready for this game. Oh and I beat the game today. Expect a review sometime...im lazy.
