The new studio headed by BioShock creator Ken Levine has finally been revealed - it's named Ghost Story.
Based in Boston and staffed by former members of BioShock developer Irrational Games, Ghost Story has actually been in business for some time - it was formed from the ashes of Irrational after it formally shut down in 2014.
Levine and friends have been quietly working on their next project for a couple of years and are now hiring a couple more key positions, including a senior designer and senior level builder.
But what will their first game be?
Ghost Story's official FAQ describes the project as a "new immersive sci-fi game with RPG elements" which is still in the "early stages of production".
One things for certain, though - Ghost Story is "not working on a BioShock game".
Here's more, in Ghost Story own words:
"As a new studio we are excited to be working on our maiden game! However, individually our team members have been involved in the development and release of many games, including but not limited to System Shock 2, BioShock and BioShock Infinite, which were directed by Ken Levine under our former moniker Irrational Games.
"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.
"We are not yet ready to share any more on our new game, but we invite you to join us and take part in our community."
Levine has previously spoken about how he wants his next project to make use of "narrative Lego" - so that a game can offer a different, non-linear story experience each time people play. Back in 2015 he described it as having a "small open world".
As for BioShock, publisher 2K recieved the rights to develop new games in the franchise when parent company Take-Two dissolved Irrational.
Ken Levine is due to give the keynote speech at EGX Rezzed, the London-based games show run by Eurogamer's parent company Gamer Network, in just a few weeks. We're likely to hear more about Ghost Story then.
