BioShock is the sort of game that the mere mention of it is enough to warrant a look. The phrase "from the creators of BioShock" simply oozes weight. And today comes the announcement of a new studio, Ghost Story, founded by a bunch of ex-Irrational developers including creative director Ken Levine, art director Shawn Robertson, and executive producer Don Roy.

So then, what are they up to? Well, we don't know for sure but as per the new official Ghost Story site, they're hard at work on "Story-driven games for people who love games that ask something of them. While we believe our new games will have strong appeal to fans of BioShock, our new focus allows us to craft experiences where the gameplay is as challenging as the stories."

Sounds pretty great, and we'll let you know as soon as anything is formally announced.
