On Sept. 14, the account tweeted its first update since June, in which the team promised to "announce an announcement" later in the week.

The Witness is designed by Jonathan Blow, whose previous game was indie hit Braid. The Witness was first announced in 2009, and is a first-person 3D puzzle game for iOS, PlayStation 4, and Windows PC.
Earlier this year, Blow shared on Twitter that The Witness was "10 [times] as big as Braid," as well as live-tweeted a speed-run through the game.
While it missed E3 this year, we had a chance to go hands-on with the game, as well as speak to Blow, at last year's conference.
