Overview
The concept of skating across a moving train track might sound absurd, but Undercoders’ Denshattack! has successfully transformed that premise into a genuinely unique gaming experience. While the core gameplay loop—launching, tricking, and grinding along a track—is not new territory, the vehicle itself provides a fresh, high-stakes twist that sets it apart. The game’s initial reveal at the recent Indie World showcase generated immediate buzz, signaling a potential return to the joyful, over-the-top spirit of classic rhythm and action titles.
The project’s genesis, according to the development team, was remarkably simple: a Japanese toy train model. This seemingly childish object sparked a line of inquiry, leading the developers to ask how a game could be built around the mechanics of skating, balance, and movement, but executed on the rails of a locomotive. This foundational concept proved sticky, evolving from a whimsical thought experiment into a fully realized prototype that the team found unexpectedly compelling.
This transformation from a simple toy to a complex, arcade-style title speaks to the power of constraints. The physical limitations and unique momentum of a train track forced the developers to innovate the gameplay mechanics, resulting in a title that manages to feel both deeply nostalgic and refreshingly novel.
The Origin Story: From Japanese Toy to Arcade Action

The Origin Story: From Japanese Toy to Arcade Action
The initial spark for Denshattack! was not a grand technological vision, but rather a play session involving a Japanese toy train model. Studio Director David Jaumandreu described the process as starting in a "very childish way," suggesting that the idea of combining the fluidity of skateboarding with the rigid structure of rail travel was purely spontaneous. This initial silliness, however, proved to be the project's greatest asset.
The core challenge was translating the freeform movement of a skateboard into the confined, linear environment of a train track. The team realized that the challenge wasn't just about movement, but about maintaining balance and executing tricks while under the constant, rhythmic motion of the train. This shift in perspective—from simulating a skater to simulating a skater on a train—is the key mechanical breakthrough.
Lead Producer Àngel Beltran noted that the initial concept made the development process surprisingly fun, allowing the team to continually build and inject "crazy stuff" into the project. This suggests that the project structure was highly iterative. Instead of adhering to a rigid plan, the developers used the initial toy concept as a flexible jumping-off point, allowing the game to organically grow into something robust enough to sustain a full arcade experience.

Aesthetic Inspiration and Setting the Scene
While the initial concept was driven by a toy, the aesthetic and setting of Denshattack! draw heavily from the rich culture and infrastructure of Japan. The developers’ deep appreciation for Japanese railways, particularly the aesthetics and variety of locomotives, provided the thematic backbone for the game.
David Jaumandreu has expressed a long-standing fascination with Japanese trains, citing his early visit to Japan in the late 1990s. The experience of observing the railway system—the different models, the high-speed lines, and the overall efficiency—cemented his interest. This admiration quickly evolved into a passion for the subject, turning him into a dedicated enthusiast of rail transport.
The narrative scope of the game is set across Japan, specifically focusing on the rural and less populated areas. This choice is critical, as these regions often feature the kind of older, more romantic train lines that still serve active passenger routes. This setting provides a perfect blend of industrial grit and pastoral beauty, offering a visually rich backdrop that contrasts the high-energy action of the gameplay.
The Mechanical Echoes of Classic Gaming
The mechanical DNA of Denshattack! is clearly indebted to classic titles like Jet Set Radio. The game taps into a specific vein of platforming and rhythm action that defined early 2000s gaming. The emphasis on grinding, jumping, and performing tricks aligns perfectly with the ethos of the genre, where style and flair are as important as the objective.
However, the train element acts as a powerful differentiator. Unlike previous titles that featured skaters on urban streets, Denshattack! introduces the unique physics of rail travel. The momentum of the train, the specific surfaces available for grinding, and the necessity of timing tricks to the rhythm of the rails create a mechanical puzzle layer that elevates the gameplay beyond simple platforming.
The development team’s ability to draw inspiration from a niche interest—Japanese trains—and merge it with a highly established, high-energy genre demonstrates a sophisticated understanding of both passion projects and marketable mechanics. It is a fusion that respects the history of the genre while simultaneously pushing the boundaries of what the platform can be.
