Irrational Games, one of the largest and most successful video game studios in Massachusetts, said Tuesday it is closing shop and turning over control of the popular “BioShock” franchise to a sister company so that cofounder Ken Levine can open a smaller house that fits with the state’s growing indie development scene.
Levine announced the move on his Quincy studio’s website, saying that he planned to launch a leaner venture focused on narrative gaming. He will retain about 15 employees for the new project but lay off most of the more than 100 people who work at Irrational.
“While I’m deeply proud of what we’ve accomplished together, my passion has turned to making a different kind of game than we’ve done before,” Levine wrote. Full story for BostonGlobe.com subscribers.
