Invincible Iron Man Gagaga-In
Main game
Invincible Iron Man Gagaga-In is a cancelled “80’s giant robot fighting action game” for the Virtual Boy, that had been in development by Hudson Soft and the planning and contract development group Eighting. It was planned to release in Japan roughly a year after the system launch.
The game has never been officially announced, but images of a design document and an EP-ROM cartridge containing a sample build have been shared in 2018 by a former Hudson employee.
