Irrational Games is reborn as a Ghost Story, is at work on a new game
The study is again captained by Ken Levine, and includes many veterans from Irrational; the team aims to create immersive games and strongly based on the story. And while the boys believe their titles will have a strong appeal against fans of the series BioShock, they also want to create experiences that, in addition to having good stories, are very challenging even in terms of gameplay.
Ghost Story Games is currently working on their first title, for which are not yet ready to release the details, nor did he know if they've acquired from any publisher. It's likely that we'll know more before E3.
