The founders of Until Dawn maker Supermassive Games are departing the company after 15 years.

In a post on LinkedIn, CEO Pete Samuels (pictured) revealed that he and commercial director Joe Samuels were leaving the studio. Pete Samuels is being replaced by investor Robert Henrysson, a partner in Nordisk Games and chair of Avalanche Studios. This news comes 17 months after Nordisk bought Supermassive.

"After over 15 years as CEO of Supermassive Games, I have taken the very difficult decision to step down from my role and leave the business," Pete Samuels wrote.

"My decision is entirely on health grounds and hasn't been taken lightly. I am, and always will be, proud of what Joe Samuels and I founded all those years ago and filled with admiration for the Supermassive team and the amazing things that they have achieved."

Henrysson added: "I’m exceptionally fired up about working with the management and all the talented people in the studio to continue developing Supermassive Games position as one of the leading studios in the world. We’re just getting started."
