"We're wholly focused on Rise being an Xbox One title without limitation, without even thinking of the Xbox 360 version," Gallagher said.
So why bring Rise of the Tomb Raider to Xbox 360 at all? Gallagher said the platform is still very robust--and with over 84 million consoles sold, there is a clear business opportunity there.
"At the same time, the Xbox 360's ecosystem is still super strong," he said. "There are millions of players out there who have an Xbox 360 and those console translations take time. So we did a test. Nixxes put together a tech demo of Rise of the Raider content running on Xbox 360, and we were totally blown away by what they achieved. But the existence of that game isn't limiting our work on the Xbox One version."
