Kane & Lynch 2: Dog Days is out in a few months time, and IO Interactive have announced that they will be supporting the title with downloadable content, just as they did with the original title.
Speaking with Karsten Lund of IO at E3, he stated "Yes [DLC will be coming], but we can't announce anything about the details of that at the moment." The DLC that supported the first title came free of charge and consisted of some new maps for the multiplayer modes. Perhaps the DLC for the second title will be more substantial?
The sequel is due out on PS3, Xbox 360 and PC in the final week of August.
