The Creation Engine 2 is an upcoming engine used to power The Elder Scrolls VI. It is a successor to Creation Engine.
On 29 June 2021, in an interview with The Telegraph, Todd Howard stated:
"The technology, Creation Engine 2, is sort of built for both [Starfield and TES VI]. It's like a new tech base. The vast majority of our development work is on Starfield right now but everybody works on everything so the projects kind of intertwine. It's good to think of The Elder Scrolls 6 as still being in a design [phase]… but we're checking the tech: 'Is this going to handle the things we want to do in that game?' Every game will have some new suites of technology so Elder Scrolls 6 will have some additions on to Creation Engine 2 that that game is going to require."[1]
