Cosmic Fantasy 4: Ginga Shounen Densetsu - Totsunyuuhen: Densetsu he no Prelude — About this game
The first half of Cosmic Fantasy 4 introduces a new stage in the series' galaxy-spanning role-playing story. Exploration, conversations and party battles alternate with animated scenes, allowing the cast's individual situations to establish the larger conflict. Pay attention to the immediate objective in each chapter, because the world opens through the events and people the party meets. Equipment and recovery supplies support the journey between safe areas, while a new companion can change the group's strongest battle choices. This Totsunyuu chapter begins the fourth adventure and is a separate release from its Gekitou continuation.
