Chet Faliszek has joined up with Worlds Adrift and Surgeon Simulator dev Bossa Studios as the director of a yet-unannounced project.

The new gig comes only months after Faliszek left his longtime post at Valve. His 12 years at the company saw him deeply involved with the stories for the Half-Life, Left 4 Dead, and Portal games as well as the most recent Counter-Strike title.

Outside of his writing work Faliszek also functioned as the studio’s VR liaison, a role that saw him working with game devs on Valve's behalf to further their VR development efforts.

Falizek’s new role, however, won’t see him working directly in virtual reality. The longtime writer and developer shared on Twitter that he would be coming to Bossa to direct an unannounced co-op action game, noting that the project would be using AI to do “something new in the narrative space.”

Meanwhile, Bossa Studios just recently secured an additional $10 million investment to fuel the ongoing development of its MMO sandbox title Worlds Adrift. Though nearing its public release, Worlds Adrift has been in the works since at least 2014 and was notably the first project to use Improbable’s SpatialOS cloud-processing tech.

At the time of the investment, Bossa Studios noted that the funds would help it both recruit "top talent" and further its work in AI. With Chet Faliszek now on board, the studio is seemingly making good on both of those promises.
