Sony has announced that Guerilla Games co-founder and managing director Hermen Hulst is now Head of Worldwide Studios (WWS).

In his new role Hulst will manage and lead game development across the 14 developers that make up WWS.

Guerilla Games is best known for the Killzone franchise that has been on PlayStation consoles since 2004, and more recently the celebrated Horizon Zero Dawn.

The studio's proprietary engine, Decima, was also utilised in Hideo Kojima's Death Stranding.

"Hermen is one of the most effective and well-respected leaders in the video game industry," said Sony Intertactive Entertainment president and CEO Jim Ryan. "He is a passionate advocate for the teams he leads and understands how to empower creative talent to build great experiences."

"Worldwide Studios is a critical part of the future success of the company, and we must deliver on the promise we have made to gamers to create imaginative and exciting content that is truly unique to PlayStation. I have no doubt Hermen can lead our teams to deliver compelling and diverse experiences at a steady cadence."

Sony also announced that Shuhei Yoshida is stepping down as president of Worldwide Studios to lead a newly-formed initiative tasked with "nurturing external independent creators." He will report directly to Jim Ryan.

This change in personnel comes after the unexpected departure of Shawn Layden last month.
