Multiple Nintendo Switch game prototypes have leaked online, including prototypes of an unreleased Ridge Racer game and a canceled RPG that was in the works by Metroid Prime series’ developer Retro Studios.
According to multiple online reports, the prototypes leaked online after they were found in a devkit, and include old Splatoon 2 debug builds, the Nintendo Switch version of RiME, an unreleased Lego Civilization game, an ARMS debug build and prototypes of a new entry in the Ridge Racer series and of Retro Studios’ canceled Project Harmony music RPG which was reportedly in development after the studio released Donkey Kong Country Tropical Freeze and Metroid Prime Remastered. Footage of the latter two games was also shared online and can be found here for Project Harmony and below for the Ridge Racer prototype.
An early build of the cancelled Ridge Racer game developed by Bandai Namco Studios Singapore has been leaked online, built on Unreal Engine 4! This dates back to January 6th, 2017.

Given Bandai Namco’s strong relationship with Nintendo, it is not surprising to see that the collaboration between the two companies was leading to the return of the Ridge Racer series on Nintendo Switch. While the game has been canceled, the collaboration between the two companies still continues to this day, as Bandai Namco is working with Smash Bros. series creator Masahiro Sakurai on Kirby Air Riders, which is launching this year on Nintendo Switch 2. A collaboration that is hardly surprising, considering Sakurai-san teamed up with Bandai Namco for the development of Super Smash Bros. for Wii U & 3DS and Ultimate.
