Division 9

A canceled co-op zombie game that was in development from Irrational Games.

In 2005, Division 9 initially started development as SWAT 5 for Vivendi Games before the team decided to incorporate "The Infected" game concept that had been in the works.

Development ended when Irrational Games was acquired by Take-Two in 2006 and focus went to the development of Bioshock.
