Lost RPG From Metal Slug Team Finally Surfaces
Decades-Old Game Boy Advance Title Set for Switch Release
A unique role-playing game, conceived by the creators of the iconic Metal Slug series, is poised for release after being shelved for over two decades. Navinosuke: The Yo-Kai Buster, originally developed for the Game Boy Advance, was hampered by the lack of a compatible GPS accessory and is now being revived by Kohachi Studio.
A Pioneering Concept
The game’s development predates the widespread adoption of location-based gaming. Akio, a designer on Metal Slug, penned the script for Navinosuke and shared his thoughts on its potential. In retrospect, if development continues as planned, the concept of ‘turning into a game’ might have been formed 15 years before Pokémon GO.
he posted on social media.
実は、ゲームボーイアドバンス時代に、GPSを使ったRPGを開発していた事がありました。
主人公は、陰陽師を目指す少女。日本列島を旅して、妖怪を封印したり、友達になったり、世界の秩序を取り戻す物語。
残念ながら、GPSの周辺機器が発売されなかったため、日の目を見ることはありませんでした。
しかし、今、このゲームが日の目を見る日が来そうです!https://t.co/wJqJq9wJ9q— AKIO (@akio_1963) February 15, 2024
The game centers around a young woman aspiring to become an Onmyoji—a traditional Japanese spiritualist—who journeys across the Japanese archipelago, sealing monsters and forging friendships to restore balance to the world.
The Rise of Location-Based Gaming
The resurgence of Navinosuke highlights the growing popularity of location-based gaming. In 2023, the global augmented reality (AR) gaming market was valued at approximately $17.9 billion and is projected to reach $84.9 billion by 2032, according to a report by Grand View Research (Grand View Research).
A Long-Lost Project Resurrected
Kohachi Studio, comprised of developers who previously worked on Metal Slug and R-Type, successfully secured the rights to the game and is preparing it for release on the Nintendo Switch next year. Akio further described the game’s core premise:
“…A Japanese fantasy role-playing game, a puppet that dreams of becoming an Onmyoji (spiritualist) girl who travels through the Japanese archipelago, seals monsters, becomes friends with them, and restores order to the world.”
—Akio
