Ken Levine has made a surprise blog post, revealing that after 17 years, he is closing Bioshock developer Irrational Games.

Irrational is today best known for their time under 2K games making Bioshock. They made their name in earlier years with System Shock 2 and the independently published Freedom Force.

Levine cites interest in going in a new direction, and plans for a more entrepeneurial position at Take-Two. He has effectively laid off all but fifteen members of Irrational, although he vouches he will take care of his former employees.
