This game, while successful in Japan, still has no US release planned.
BERSERK for PS2 is a 3rd-person hack-and-slash with similar gameplay elements to its Dreamcast predecessor. The plot is taken directly from the manga, from volumes 22 - 27. Improvements to the gameplay include realistic character model dissassembly, which basically means you can slash heads and other body parts clean away from enemies. In addition, there is an action-cutscene system where users can input button commands at key points in battle to unleash large, dramatic attacks, reminicent to those in the manga. Guts' new allies, such as Serpico, Isidro and Schierke can now be called briefly into battle, used as a type of summon. And of course, Guts still has his Berserk meter, which he can unleash once it has filled up, dishing out massive destruction in the process.
While much of the game's story follows the events of the manga, there is one episode that is completely unique to the series, involving an boy named Charles. Charles traps Guts in an illusionary world and summons images of The Band of Hawks, who Guts eventually must battle to escape the dream.
