Human stretch goal Chris Avellone, formerly of Obsidian Entertainment and one of the creators of Icewind Dale, Planescape Torment, and Fallout: New Vegas, is working at Arkane Studios on the new Prey. Since leaving Obsidian last year Avellone has been appearing on the credits of a growing list of games from developers around the world, most recently Divinity: Original Sin 2, where his involvement was unlocked as a stretch goal on the Kickstarter.
Avellone hasn't officially joined Arkane so this is likely a freelance gig. He confirmed his involvement with this subtle tweet:
