Sony Online Entertainment, based in Sorrento Valley and the maker of massively multiplayer online games such as EverQuest, said it laid off an undisclosed number of employees in a restructuring it announced a few weeks ago.

The cuts were made at SOE’s head office in San Diego and in Austin, Texas, but a spokeswoman declined to reveal details.

“The reductions were part of a strategic decision to reduce costs and streamline our workforce to align our development resources with our current portfolio of games,” said SOE’s Michele Cagle.

“I would like to point out that this strategic decision will have no impact on the development of our upcoming games, including EverQuest Next Landmark or EverQuest Next,” she said.

According to a notice SOE filed with the state, complying with the Worker Adjustment and Retraining Notification Act, the company is reducing its local workforce by 70 positions effective Oct.28.

SOE, which is part of Sony Corp., said in 2010 it had about 500 employees in San Diego.
