BioShock 2 developer 2K Marin, has left the company. His departure should have no effect on the studio's current project, The Bureau: XCOM Declassified, which he moved away from in early 2012, he tells GI.biz.
Thomas makes his exit from the company to go indie with an unnamed partner and work on his own projects. He came to the decision after helping Irrational Games finish work on BioShock Infinite. "It cemented for me that while BioShock spoke to me, it'll never be for me what it is for Ken. I've expanded that legacy here and there, but I could never have created it from scratch. I need to build something that is, to me, what BioShock is to Ken. No matter how long it takes, I have to start now."
Thomas already has a game in mind, of course: He wants to take some of the ideals found in Thief and BioShock and apply them "with a radically different focus." If it's well-received, Thomas says "we might expand the vision and explore further dimensions of the same theme with more content producers. But we'd love to keep it as lean as possible for now, in the hopes that we're not writing checks our asses can't cash. Indie ambition is its greatest strength and its greatest weakness."
