Retro Replay Review

Gameplay

The transformation is the reason to play Akū Senki Raijin. On the ground, Raijin moves and aims in four directions through connected, single-screen areas. In flight, the game turns into a side-scrolling shooter with a fixed direction of travel. That is a sharp enough change that you cannot coast on one set of habits. The game keeps asking whether you are more comfortable picking through compact combat spaces or handling the directional combat of a scrolling shooter.

The on-foot sections have the more deliberate rhythm. Moving through linked screens gives them a light exploratory feel, and being able to aim separately from movement adds more intent than simply charging ahead. The flight sequences are the cleaner burst of action, built around surviving what comes at you in side-scrolling battle scenes. Neither half is especially exotic on its own, but putting them together gives Raijin a personality that many shooters from its era lack.

Between levels, you can spend on weapons, shields, and ammunition. That gives the game a practical layer of preparation instead of treating every stage as a totally self-contained test. It also means your choices matter before you head back out. Anyone who dislikes managing finite ammunition may find that friction unnecessary, but it suits a game built around a military machine responding to a larger threat.

The drawback is that hybrid design can feel less polished than a game devoted to one style. Switching forms is exciting because the pace changes so dramatically, yet you may prefer one half enough that the other feels like an interruption. Still, the contrast is the point. Raijin is most rewarding when you meet it on its own terms rather than expecting an uninterrupted shoot-’em-up run.

Graphics

The two forms create a clear visual contrast in play: contained single-screen areas frame Raijin’s ground combat, while the spaceship form takes the action into side-scrolling battle scenes. That change of view helps the transformation feel like a real shift in role rather than a cosmetic swap.

Story

The setup is direct sci-fi pulp. The machine form Galem attacks five subspace relay points known as the Field, and the Galactic Union sends Raijin to eliminate the threat. It is a clean excuse to launch a mechanized unit into hostile territory, and the game does not need to overcomplicate it.

What helps is that the premise matches the structure. Raijin is a mechanized mobile unit, so transforming between a ground-capable mech and a spaceship feels like a natural part of its mission. The story gives the changing gameplay modes a basic logic without getting in the way of the action.

Do not come here for layered characters or a sprawling narrative. This is a compact mission framework, closer to the opening of a vintage anime robot adventure than a story-heavy role-playing game. Its value is in giving the combat a little context and making Raijin’s unusual versatility feel purposeful.

Overall Experience

Akū Senki Raijin is a neat oddball: a game that refuses to settle for being only a four-direction action game or only a side-scrolling shooter. Its strongest moments come from that tension between methods. One moment you are navigating connected combat screens with measured movement and aiming; the next, you are flying forward through a scrolling attack sequence.

You should give it a chance if you enjoy digging into early Japanese action games with one strong, unusual idea at the center. The purchasable weapons, shields, and ammunition add enough planning to make the mission feel less disposable, while the transformation keeps the action from becoming monotonous.

It is easier to recommend as a curiosity with real substance than as an all-purpose shooter essential. The hybrid structure will either be the feature that wins you over or the reason it never fully clicks. For the right retro gamer, though, that willingness to splice two distinct action styles together is exactly what makes Raijin memorable.
