The year is 2035, and Soma Cruz is about to witness the first solar eclipse of the 21st century when he suddenly blacks out—only to awaken inside a mysterious castle. As Soma, you must navigate the castle's labyrinths while confronting perilous monsters at every turn with physical attacks and magical spells. Using the Tactical Soul system, collect souls of enemies to learn their abilities and equip them to activate new powers. But beware—you must escape before evil consumes you! Once you've survived the horrors of the castle, there are four other modes waiting for you to try.
