Denshattack! Reveals Its First Boss Battle, and Yes, It Is a Train Mecha Duel

Undercoders has shared a deeper look at Denshattack! ahead of its July 15, 2026 launch on PlayStation 5, and the spotlight is on one of the game’s strangest and most memorable ideas: a boss fight between a stunt-performing train and a giant magical-girl-style mecha. The PlayStation Blog post was written by David Jaumandreu, Studio and Game Director at Undercoders, and introduces Yoshie, the first boss players will face in the game.

Denshattack! is described as a fast, trick-based action game where players kickflip, grind, ollie, race, and complete objectives as a train. The studio says the game draws inspiration from extreme sports series like Tony Hawk’s Pro Skater and SSX, while also leaning into colorful Y2K cel-shaded energy associated with arcade-style games and Japanese pop culture influences.

The game’s world has a sharper edge beneath the bright style. Denshattack! takes place in a future Japan shaped by climate disaster, where wealthy citizens live inside protected air-purifying domes while everyone outside survives in abandoned, undomed regions. The Denshattack movement reclaims old railway lines and turns them into battlegrounds for underground duels built around speed, tricks, and technique. The main character, Emi, is a young ramen delivery girl who gets pulled into that world after meeting a journalist, then travels across Japan from Kyushu to Hokkaido while learning new skills and challenging regional gang leaders.

That structure gives the game its boss battles. Undercoders says each region is controlled by a gang with its own identity, music, fashion, and leader. The goal is to make each chapter end like a big shonen anime showdown, where the player has to apply everything they learned in the preceding levels. That design approach is important because it turns boss fights into skill exams rather than isolated spectacle. The player is not just watching a wild set piece; they are expected to use tricks, movement, timing, and combat mechanics under pressure.

Yoshie leads the Dashing Queens and comes from Fukuoka. Undercoders presents her as an influencer whose popularity becomes so powerful that the government sees her as a threat. Her design is built around gyaru fashion and attitude, with a loud, confident visual identity that extends from her character design to her train. During the battle, Yoshie’s train combines with her soldiers and transforms into a huge magical-girl-inspired mecha filled with bows, stars, hearts, and sentai-style flair.

Mechanically, Yoshie’s fight follows a multi-phase boss structure. Players first use tricks and combos to reach the main battle, then rely on quick rail changes to avoid attacks. Once the fight escalates, Emi can use grinds and ground pounds to damage the mecha. According to Undercoders, the fight is built around techniques introduced during the first chapter, making Yoshie both a personality showcase and the first major test of the player’s control over the game’s train movement systems.

The boss music also gets its own identity. Yoshie’s battle theme is a collaboration between composer Sean Bialo, Vocaloid producer Yunosuke, and pop singer and real-life gyaru idol Alice Peralta. That matters because Denshattack! is clearly treating music, fashion, and regional identity as part of the game’s worldbuilding, not just background decoration.

What is not confirmed in this post is the full number of bosses, total game length, pricing, or whether Denshattack! will come to platforms beyond PS5. For now, the confirmed detail is that Denshattack! launches on PS5 on July 15, with Yoshie serving as the first major boss battle.
