During an investor call, Take Two announced it will release a sequel of its widely-acclaimed game, Bioshock.

The Take Two execs said that the new game, which for the moment was introduced as Bioshock 2, will be developed by 2K Marin, but they confirmed that Ken Levine will be involved in the development of the new game.

The launch date is still uncertain, but Take Two said that the game is scheduled for Q2 2009, which means that it is possible that the game will be released sometimes during August-October period.

In Bioshock, which was released in August last year, players enter the game as a castaway in Rapture, an underwater utopia torn apart by civil war.
Caught between powerful forces and hunted down by genetically modified "splicers" and deadly security systems, players have to come to grips with a dangerous and mysterious world filled with powerful technology and fascinating characters. With multiple avenues for surmounting challenges on both a moral and tactical level, no encounter ever plays out the same. The game sold 2 million units since its release across both the PC and Xbox 360 platforms

Take Two also hinted about a new Max Payne title, especially since the movie is on its way and it seems like a new sequel of Grand Theft Auto will be released in Q4 2009.
