Ken Levine, co-founder of Irrational Games and famous for being the Bioshock series creator, writer and director, has taken to Twitter to reveal some early details about his first game since the studio was shut down last year.

He revealed that the project will likely be first person and it will be a "small open worldish (but not necessarily outdoors) RPG" with a "quest structure" that comes from what he calls a "passion system". The setting is said to be "something sci fi. Or sci-fi ish."

Levine also stated that it would be narrative driven, like his previous games, and focus on smaller interactions with the story, rather than the impactful ones seen in Bioshock and follow-up Bioshock Infinite.

The development process is now focusing on gameplay and narrative systems. Levine also explained what had been worked on up until his impromptu Q&A yesterday.

One fan also questioned Levine about the AI in the game, and whether it would be smarter than Bioshock Infinite companion Elizabeth, to which he said his team were taking a "very different approach than Liz" but that he does miss her.

Asked about his long term aims for the game, Levine said he wanted to create "A game with replayable narrative that can be added in-to like a [Civilisation] expansion pack, versus say a [Bioshock Infinite] Burial at Sea."

The game is currently being developed for PC and in a little reference to Infinite, Levine promised there wouldn't be a lighthouse in this game. He also revealed he'd be at PAX East in March where it's likely we'll hear more about the project in its early days.

When Irrational Games was shut down Levine left to form his own new studio which would be developing digital download games for Take Two with a strong focus on "narrative-driven games for the core gamer that are highly replayable."
