Portal writer Chet Faliszek joins ex-Riot dev to make an AI-driven co-op game

The new studio is Stray Bombay, and will aim to revolutionise co-op gaming and emergent stories

Chet Faliszek and Dr Kimberly Voll have set up a new studio named Stray Bombay, which will focus on making co-op games. The pair are veteran game developers; in his 12 years at Valve Faliszek helped write both Portal games, both Half-Life episodes, and both Left 4 Deads, while Voll has been principal technical designer at League of Legends studio Riot since January 2016, and has a background straddling human-centric game design, cognitive science, and artificial intelligence.

Last we heard, Faliszek had left Valve for Bossa Studios, where he was directing a co-op action game that would use AI to “push the boundaries of emergent narratives.” His joint announcement with Voll today doesn’t mention Bossa or his game there, but it sounds like his interests haven’t changed: in language reminiscent of Ken Levine’s mysterious new project, it sounds like he’s having another tilt at revolutionising game storytelling.

Faliszek says Stray Bombay will use AI to drive “not just the enemies” but “the entire experience” of its games, which will “tell stories knowing you are going to come back again and again” and “change each time you play them without feeling completely random”.

The announcement comes just as the Game Developers’ Conference 2019 is kicking off in San Francisco and Stray Bombay are looking to hire (resumes to [email protected]). The new studio has financial backing from Upfront Ventures and from Voll’s own former employer, Riot Games, who says “Kim is a brilliant game designer and her passion for helping players collaborate in positive, productive ways is a surefire recipe for memorable experiences.”

Despite this funding, it’ll be a while before players hear anything more from Stray Bombay. The studio says it is “going to go dark for a little bit as we start laying the foundation of our new world.”
