Sega will cut around 300 jobs as a result of ongoing restructuring at the company.

Up to 300 employees will be approached with offers of "voluntary retirement" as a part of the company's broader efforts to focus on mobile and online PC gaming, reports CNBC.

120 of those employees currently work at Sega of America. The company will move its US headquarters from San Francisco to Southern California.

“We are confident that by relocating to Southern California we will be able to thrive, grow and become a stronger company because of it,” said Sega of America president John Cheng.

“This move was crucial to keep Sega operations moving forward throughout North America and to provide our millions of fans a strong pipeline of content across gaming, TV, merchandising, and more.

“We are sad to say goodbye to some of the best people in the business and are indebted to them for their hard work and dedication through the years.”
