Outer Wilds developer Mobius has officially confirmed Echoes of the Eye, the game's "first and only expansion" which will arrive on 28th September for PC, PlayStation and Xbox.
The story of this new chapter, revealed as part of tonight's Annapurna Interactive showcase, remains largely a mystery.
"It's going to weave directly into the existing world and narrative," creative director Alex Beachum teased. "Now, if you've played the game, you might be wondering how. And also why. And those are very good questions."
