Thanks to this, we now know a few more details about the game, launching November 29 in Japan. First, Billion Road will support TV Mode, Handheld Mode, and Tabletop Mode. It’s also compatible with the Nintendo Switch Pro Controller and Save Data Cloud Backup feature.
The game has also reconfirmed support for up to 4 players on the same Nintendo Switch, and it will require 232MB (very tiny!) of space.
Unfortunately, Billion Road is only playable in Japanese. Shouldn’t be surprising as the Momotaro Dentetsu games have never been localized outside Japan.
