UK games developer Sumo Digital is restructuring ahead of expansion plans.

The Sheffield-headquartered firm has moved into larger offices in both the Steel City and its other UK base, Nottingham.

Sumo is behind hit titles such as Forza Motorsport, LittleBigPlanet 3 and Dead Island 2.

Co-founder Paul Porter is now the managing director while David Wilton has joined as chief financial officer and Gary Dunn is the new portfolio director.

Dunn worked closely with the studio in his time at Sega, as Sumo developed titles such as Outrun 2, Outrun Coast 2 Coast and Sonic & Sega All-Stars Racing.

“Having worked with Sumo for over a decade, it was an easy decision to join the team as it prepares for explosive growth across their studios in the UK and India,” said Dunn.

The firm, which employs 400 staff in Sheffield, Nottingham and Pune, India, has also named Jim Woods as senior development director, Scott Kirkland as a development director and Martin Connor as studio design director.

The company employs more than 400 staff across its three studios in Sheffield & Nottingham, UK and Pune, India.

Sumo was bought by private investment firm Perwyn last year after a period of huge growth following a 2014 management buyout assisted by NorthEdge Capital.

It had previously been bought by US firm Foundation 9 Entertainment in 2007.

Earlier this year Sumo acquired art and design studio Atomhawk, which worked on Marvel Studios’ silver screen blockbuster Guardians of the Galaxy as well as leading console games.

The studio is reportedly preparing for an initial public offering worth up to £150 million.
