Alnam no Tsubasa is a sequel to Alnam no Kiba. Like its predecessor, it is a Japanese-style role-playing game with a character-driven story, linear advancement, and simple leveling-up. Combat is turn based, with up to four player-controlled characters forming a party. Characters can attack physically, cast spells, or execute special attacks that take up a part of a corresponding gauge. Magic is learned by receiving magic points for winning battles and using them to create various spells. The game features 3D background graphics with 2D sprites representing characters.
Treasure Isle is rumored to hide a vast bounty of gold said to be guarded by the legendary beast "Yamawara", which Kindaichi and other treasure hunters gather to search for. But the host is killed before the group even arrives, and a bloody slaying takes place during a time in which none of the people on the island could have done it. Will the island's mythical monster-guardian claim more victims?
