"The day to day operations of Defiance will be moved to our Redwood City studio where it can be managed alongside Rift and our other in development titles including ArcheAge and End of Nations," a company spokesperson said.
The closure is part of "a new strategy at Trion," according to new CEO Scott Hartsman. Hartsman, who worked on Rift, left Trion earlier this year, saying game development is "fundamentally broken." However, effective immediately, he will head his former employer.
"We're going to rapidly be laying the groundwork for a new strategy at Trion--one that's closer to the foundation of how we've had our wins so far, and then extending that base into the enduring success this company can, and will, be," he told Gamasutra.
