After the recent defense of the Nanairo system from the Krawl swarm, Rallen, a young and hardheaded planetary police officer, and Jeena, his sensible and technologically adept partner, enjoy several months of peace. However their peace is disrupted when their friend Aldous, a mysterious man from a distant star system, is kidnapped by a Krawl superior known as Maja, one of the High Krawl. Even worse, a series of mysterious portals are opening up around the Nanairo system allowing Rallen and Jeena access to different star systems - and the Krawl access to the Nanairo system. Now, with the help of brand new Spectrobes and a vicious breed of Dark Spectrobes, Rallen and Jeena must venture across the universe to rescue Aldous and defeat the four High Krawl.
Gameplay in Beyond the Portals functions similarly to that of its predecessor. Players predominantly control Rallen in the field, although from time to time, they will be able to control Jeena to solve puzzles. Five planets of the Nanairo Star System, from the first game are accessible once more. At certain points in the game, portals will open that will allow the player to travel to different star systems. There are a total of ten planets and three portals spread out over four star systems. During normal gameplay, the player is given the option to play a mini-game, flying the Patrol Cruiser, whilst dodging asteroids, in order to travel through a portal that links to another star system.
