Aero-Cross is a cancelled sequel to Namco’s classic Metro-Cross, a racing-platform game that was released in arcades in 1985. This new chapter planned PlayStation 3 Network and Xbox 360 Live Arcade was announced in 2011 and it would have been released for the “Namco Generations” series, conceived to modernize some of their classic titles, such as Pac-Man Championship Edition DX and Galaga Legions DX.
Aero-Cross would have followed the same gameplay as the original, with players running in linear levels trying to avoid obstacles and collecting items (but this time in a sci-fi setting). In the end the project was officially cancelled in 2012 along with the other missing Namco Generations title: Dancing Eye HD. Luckily in this case a playable demo for Aero-Cross was found by Ganonthegreat on an old PS3 demo-disc, and shared online on Archive.org
