'Gate of Thunder' was also a pack-in game for the TurboDuo in North America. The player controls the spaceship Hunting Dog, piloted by a space cop named Hawk. Along with ally Esty and her ship the Wild Cat, Hawk must stop General Don Jingi and his Obellon army from taking a powerful energy source called "Starlight" from the planet of Aries. 'Gate of Thunder' is considered to be one of the PC Engine's most well regarded games, with the quality of the game's Red Book CD audio music soundtrack continuing to be highly praised to this day.[
