Mystery of the Soulriders follows four girls as they combat evil forces in their town through the power of friendship; both with each other, and with their magical talking horses. The game opens with Lisa, on her first day of school, helping the horse Starshine ride again. But who is the old man Mr. Sands, and why does Starshine feel pain whenever he is near?
Gameplay is third-person adventure, and levels are in full 3D. Walk around and talk to people, collect and use items. There is, of course, horseback riding, which controls similarly. There are golden stars hidden in out-of-the-way places in each level, so keep your eyes open.
