Bethesda has revealed a new IP during its E3 2018 media briefing. Starfield is a next generation, single-player game. It is its first new franchise in 25 years.
Only a brief teaser trailer for Starfield was shown during the presentation. We see a planet first. Then, it pans down to some kind of satellite orbiting it. A rift opens, blowing the manmade object away.
Starfield is currently in development.
