Just like clockwork, Bandai Namco have followed up their Gundam RG XARX-ZERO trailer with details of the game that shares the same universe, albeit 100 years after the anime.
The game reiterates that it's a "high-mobility" action game that links to the anime. Most notably, the game's description expands on the storyline:
In GUNDAM ROGUE ORBIT, players will become a Gundam pilot in an original story set beyond the events of the anime. In this story, three revelations were delivered by the Autonomous Interstellar Object from another galaxy ushered in an age of unprecedented prosperity, allowing humanity to expand across the entire solar system. Gravity Control. FTL Communication. Cognitive Materialization. Yet less than ten years after its discovery, the Object that had delivered these three revelations suddenly ran rampant, spawning an aggressive, self-proliferating ecosystem. Humanity came to see this unknown ecosystem as the Apocalypse. For three months, humanity fought the Apocalypse to a standstill in orbit above Earth. Forced to abandon the planet, humanity marked that year as A.A. 1—the first year After Apocalypse.
By A.A. 45, children born on the Moon and in space colonies have never known life without the Apocalypse. And on the lunar surface, a boy named Ray Azumi awakens.
And here's the trailer! Shades of Pacific Rim in the music when the Helix enters.
The Bandai Namco podcast also had some details:
The press pack also has some lovely mecha designs:

Apocalypse
There was also some renders of the upcoming Helix Gunpla:

Finally, we have some screenshots from the game in the gallery below. It certainly looks interesting and we like a good Gundam game (especially the arcade Vs series) so fingers crossed the game is worthy of the world that Kenji Kamiyama and Toh Endoe have created for it.
