"We're going to rapidly be laying the groundwork for a new strategy for 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 said, according to a company press release.
Hartsman previously served as chief creative officer on RIFT. He succeeds Lars Buttler, who remains a Trion board member.
[Updated: Trion has also confirmed the closure of its San Diego studio. "We can confirm that the San Diego studio will be closing. 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. As part of this transition, we are working hard to ensure that a number of great people will be making the move from San Diego to the Bay Area and continue their work at Trion," the studio told PC Gamer.
