2K Marin Developing an Xbox 360 Exclusive

Despite not having the same number of first party studios as Sony or Nintendo, Microsoft has generally managed to keep up with their rivals when it comes to exclusive titles. However, with more and more developers moving on to Kinect, or going multiplatform, the 360's core exclusive lineup is looking rather weak. Fret not 360 fans, Bioshock 2 developers 2K Marin are working a 360 exclusive.
