A trailer for a new Gundam game titled SD Gundam G Generation Cross Rays was published on the Bandai Namco YouTube channel but was then quickly removed. As its title states, Cross Rays looks to be another game in the long line of G Generation games, appearing to show a variety of Gundams up to Iron Blooded Orphans. It can only be assumed that it will contain a large collection of Mobile Suits from all the various Gundam games/series before it, like previous G Generation games have.
Currently the platform it will be released for is unknown, but more info will be announced on Famitsu at 1:00 pm JST on January 22nd.
