Game Vortex writes: "Spectrobes didn't set the monster-collecting genre on fire, but it was a fun, solid experience. With the sequel, Spectrobes: Beyond the Portals, Disney and Jupiter have gone back and retooled the experience. Though there are some noticeable improvements, there are still a few lingering problems.
Everything is presented in full 3D. Even though 3D isn't one of the system's strengths, it fits the game's stylized art style. There are 185 Spectrobes to collect in the game and all look really good. Each has its own traits, but still manages to retain a look that is consistent with the rest of the world. All of your Spectrobes can evolve into different types and you can even swap out parts, adding a lot of variety to the game. Even more impressive is the lack of major slowdown. The framerate catches a bit of a hitch when there are a lot of monsters on the play field, though this mainly happens when they're unleashing a number of effects-laden attacks."

"What's good about Spectrobes: Beyond The Portals as a game is that it offers hours of challenge for young gamers. What's good about it as a sequel is it represents a big step forward from the first game. If the progress continues, Spectrobes will establish itself as one of the leading game series for children on the DS."
GamesWeasel writes: "Unfortunately, combat's not great. Fighting as Rallen you can use melee attacks or your gun, but locking onto enemies is tricky when the camera's not centred on them. Fighting with your Spectrobes is really boring. By walking into a Vortex, you set your tag team into motion, but combat is no more than walking up to an enemy and pressing A, then pressing B or Y when you're charged up a super move. It's clunky, unresponsive and dull.
Exploration isn't great either. Although they've improved the camera angle to make it less claustrophobic, there's still a lot of back-tracking to do, and if you die, you start back at your ship and have to wander through the barren lands once again".
PALGN writes: "For those that played and enjoyed the first Spectrobes title, you'd be pleased to note that it is a better title than its older sibling, marginally better. For the rest of us, you'll be hard pressed to find much value in Spectrobes: Beyond the Portals, unless you are a complete addict for monster-collecting games - or under the age of ten.
Beyond the Portals sees the return of Rallen, the Nanario Planetary Patrol officer who curtailed an alien invasion at the end of the first Spectrobes tiltle. Obviously, the invading Krawl had other ideas, forcing Rallen and friends to stop the evil alien race all over again."
